publicityOrigin of Oxygen to Human Impact
The oxygen generated by these living beings slowly accumulated in the atmosphere, which changed its composition and created, around 400 million years ago, the conditions necessary for the formation of an ozone layer. This layer is capable of filtering ultraviolet radiation, thus allowing living beings to colonize terrestrial environments outside of water. The enrichment of the atmosphere with oxygen, produced in photosynthesis, allowed this gas to become available and be used by living beings in cellular respiration, which in turn releases the carbon dioxide consumed in photosynthesis into the atmosphere. The Earth's atmosphere has undergone continuous changes in its composition over geological time, responsible for drastic climate changes and mass extinctions. Currently, it is human activities that produce a growing and global impact on the atmosphere with consequences that are still difficult to predict.
Evolution of the Atmosphere
The Earth was an uninhabitable place with no breathable air for hundreds of millions of years after its formation. Over time, however, it developed an atmosphere that was quite different from the one we know today. The primitive atmosphere was composed of methane, ammonia, hydrogen, nitrogen, carbon dioxide and water vapour, but there was no oxygen. Oxygen only appeared in the atmosphere due to its release by living beings, namely through photosynthesis. The first photosynthetic beings were not plants or algae, as they did not yet exist. The first living beings to carry out photosynthesis and release oxygen into the atmosphere were microorganisms similar to today's bacteria that began to appear in the primitive oceans, more than 3,000 million years ago.
The Importance of the Atmosphere for Life
Atmosphere: The atmosphere plays crucial roles in sustaining life, such as filtering harmful ultraviolet rays through the ozone layer , protecting against meteorite impacts , and regulating the environmental temperature compatible with life through the greenhouse effect . These characteristics help create suitable conditions for life. The existence of the atmosphere is possible due to the size and mass of the Earth, which generate sufficient gravitational attraction to keep this layer of gases attached to its surface. Without this gravitational force, the atmosphere would disperse into space.
publicityEssential Elements for Life on Earth
Geosphere dynamics: The movement of tectonic plates and the rock cycle are processes that shape landscapes, form soils and create new environments, driving the evolution and diversity of species. Water: The abundance of liquid water is essential for life, as it makes up between 70% and 90% of the body weight of living beings and participates in all their vital processes. Natural environments: The variety of habitats on Earth favors the capacity for adaptation and the growth of biodiversity, increasing the chances of survival and continuity of species.
The Influence of the Moon and the Giant Planets
The Moon and the giant planets: The movement of the Moon around the Earth helps to stabilize the axis of rotation, maintaining a constant tilt, which is crucial for the cycle of the seasons . In addition, the gravitational force of the Moon is responsible for the occurrence of tides and ocean currents , which influence the Earth's climate . The gravity of the giant planets, especially Jupiter, attracts asteroids and comets that could collide with the Earth and cause extinctions . Earth's magnetic field: This field acts as a protective shield, deflecting much of the harmful radiation emitted by the Sun.
Essential conditions for life on Earth
Earth is the only planet in the Solar System that has the ideal conditions for life as we know it. Some of the factors that make this possible include: the perfect distance from the Sun, the influence of the Moon and the giant planets, the presence of a magnetic field, the dynamism of the geosphere, the abundance of water, the diversity of natural environments and a protective atmosphere. Distance from the Sun: Earth orbits within the habitable zone of the Solar System, at a distance that allows the presence of liquid water on its surface.
publicityThe Origin of the Conditions for Life
Some important events in Earth's history that created the conditions for the emergence of life over thousands of years include: the formation of the planet with impacts from other bodies in the Solar System; the creation of a solid crust, with continents and oceans; the development of an atmosphere with a greenhouse effect; the movement of tectonic plates and volcanic activity; atmospheric electrical phenomena; the formation of simple organic molecules and macromolecules; the emergence of the first primitive cells; the beginning of photosynthesis and the production of oxygen; the creation of the ozone layer and superglaciations that gave rise to new environments.
Planet Earth
Earth is a unique and extraordinary planet, being the common home of all species, where we still enjoy the best conditions of comfort, sustenance and protection for life. However, it was not always like this. The planet we know today is the result of a complex process of transformations that began about 4.6 billion years ago. With the advancement of science and technology, human intelligence has made our species the most dominant, capable of influencing natural processes, consuming large amounts of resources and, thus, shaping the future of the planet. Now, we have the responsibility to ensure the survival of all the species that share the Earth with us.
Curiosities, games, challenges and quiz about The
The discovery of penicillin: a revolution in medicine. In 1929, by a stroke of luck, Alexander Fleming found the first antibiotic, penicillin. During World War II, its potential was extensively tested, saving countless lives. Noel Rosa and many other artists could have been saved from tuberculosis if this discovery had occurred earlier.
The curious thing is that Fleming, a researcher dedicated to bacteria, left a culture plate forgotten during the summer. By chance, some bread crumbs fell on it, creating fungus. When his colleague Merlin Pryce noticed something strange in the plates about to be discarded, Fleming realized that the fungi had eliminated the bacteria, giving rise to penicillin, a milestone in the history of medicine.
publicityCuriosities, games, challenges and quiz about Rocks
Rocks are natural formations composed of cohesive minerals, resulting from geological processes. Minerals, in turn, are solid inorganic substances, with a crystalline structure and defined chemical composition. Unlike organic components, minerals have an ordered arrangement and can form crystals visible to the naked eye, as in granite.
Curiosities, games, challenges and quiz about Natural Sciences is short for Biology

In this course, students examine and study the elements of nature around them, addressing the environment, the life cycle and interactions between living beings. Other subjects addressed include climate change, biodiversity, ecosystems and human influences on nature.
Curiosities, games, challenges and quiz about Reproduction
Reproduction is the function that allows the continuity of life and is common to all living beings. In humans, reproduction is sexual, as it is possible by the union of two sex cells: one female, the oocyte, and the other male, the sperm. When the human being is born, we can only identify the sex of the baby by observing its genitals. Thus, we call these organs primary sexual characters – the penis and the vagina. As we grow, our body undergoes changes in its external appearance – secondary sexual characteristics – which in adolescence already allow us to distinguish between girls and boys.
publicityCuriosities, games, challenges and quiz about Adolescence
Adolescence begins with puberty - from 8 to 14 years old, in girls, and from 9 to 15 years old, in boys. This is the phase in which not only major physical changes occur, but also psychological and even relational changes. In this phase, the "chemical messengers" - the hormones testosterone, in boys, and estrogen and progesterone, in girls -, which were inhibited in childhood, trigger the appearance of secondary sexual characteristics, giving human beings the physical traits they will have in adult life. Sometimes during adolescence, pimples appear on the face. This inflammation and obstruction of the pores of the skin, called acne, is caused by an increased production of sebum (fat) from the sebaceous glands of the skin, due to intense hormonal activity.
Curiosities, games, challenges and quiz about The
The male reproductive system consists of: the testes, the vas deferens, the seminal vesicles, the prostate and the penis. Starting at puberty, the testes continually produce millions of sperm, the male sex cells. The sperm, together with a fluid from the seminal vesicles and the prostate, form the sperm. The emission of this liquid to the outside of the body is called ejaculation. Seminal vesicles (Produce a viscous fluid); Prostate (Produces the milky and thick liquid that mixes with the seminal fluid, providing the nutritive and transport medium for the sperm); Deferent ducts (carry sperm from the testicles to the penis) Urethra (Channel common to the reproductive and urinary systems); Scrotum (skin pouch that surrounds the testicles); Penis (Organ that conducts sperm to the outside) and Testicles (Located outside the body, inside a bag, the scrotum. They produce sperm).
Curiosities, games, challenges and quiz about The female reproductive system
The female reproductive system is made up of: the ovaries, the fallopian tubes, the uterus, the vagina and the vulva. The ovaries produce the female sex cells called oocytes. The girl has the full amount of oocytes at birth and, as soon as she menstruates, she monthly releases one oocyte from each ovary, alternately. Uterus (muscular organ, hollow, in the shape of an inverted pear and with very elastic walls where the new being will develop. The lower part is called the cervix); Fallopian tubes (Two channels through which the ovaries communicate with the uterus); Ovaries (They are about the size of an almond. Their function is to produce oocytes) and the Vagina (It forms the connection between the uterus and the outside and its walls are elastic and muscular).
publicityCuriosities, games, challenges and quiz about In a flowering plant reproduction
In a flowering plant reproduction is sexual and is carried out by seeds. The flower is the organ responsible for the reproduction of the plant. Its various constituents have different and specific functions that, together, allow the reproduction of the plant, that is, allow the joining of female and male sex cells to give rise to the egg or zygote, the first cell of the new being. Support organs (The receptacle and the peduncle support the entire flower); Protective organs (The corolla - set of petals and the calyx - set of sepals, protect the reproductive organs); Reproductive organs (The carpels - set of female organs and the stamens - set of male organs, are responsible for plant reproduction); the Anthers (they are made up of small sacs full of pollen grains that give rise to male sex cells. The oosphere, the female sex cell, is located in the ovaries).
Curiosities, games, challenges and quiz about The
The transfer of pollen grains from the anthers to the stigma of the same or another flower is called Pollination, which allows the meeting between the male sex cell and the female sex cell. Pollination agents are responsible for transporting pollen grains from the stamens of a flower to the stigma of the same flower, or from one flower to another. Without these, the pollen grains would have difficulty reaching their destination and reproduction might not occur. Insects, wind, some mammals and birds, water and man are examples of pollination agents. Pollination can be direct (by self-pollination) or indirect (by crossing with another flower of the same plant or with flowers of different plants of the same species). Direct pollination (Pollen from a flower lands directly on the stigma of that same flower) and Indirect pollination/9 Pollen from a flower lands on the stigma of another flower on the same plant or on a different plant).
Curiosities, games, challenges and quiz about The process of seed dispersal
The process of seed dispersal is called dissemination. This process is extremely important for the seeds to be taken to other places, often far from the plant that originated them, and thus be able to colonize new environments. Dissemination can be carried out: by animals (including humans), by wind, water and by the plant itself (mechanical dissemination). When it finds a place with adequate temperature, humidity and light conditions, germination takes place, that is, the seed becomes a new plant. In the seed, there are specific structures that will give rise to the various organs of the future plant: the radicle (will give rise to the root of the plant), the caulicle (will become the stem of the plant), the bud or plumule (from which the first leaves of the plant). The cotyledons (contain food reserves, which the embryo needs) and the integument (protects the entire seed).
publicityCuriosities, games, challenges and quiz about Microorganisms
Microorganisms are organisms so small that they are invisible to the naked eye and can only be observed with the help of a microscope. Micro-organisms exist in the most varied habitats: in the air, soil, water, inside our bodies or on the walls of our homes, for example. To develop they need adequate conditions of humidity, temperature, oxygen and nutrients. We can identify several groups of micro-organisms: Protozoa (Trypanosoma brucei - sleeping sickness); Bacteria (Escherichia coli); Viruses(Ebola Virus) and Microscopic Fungi(Mold Fungus). Important micro-organisms for humans: Pathogenic microorganisms (they cause diseases such as flu, pneumonia, athlete's foot and sleeping sickness) and Useful micro-organisms (they are useful in the daily life of human beings, for example, the yeasts that we use to make bread or the bacteria in yogurt).

With the development of societies and technology, new threats to the planet also arise. Thinking he is doing his best, man is destroying his home, the Earth, polluting the soil, air and water. The main causes of air pollution are: the burning of fossil fuels; agriculture and livestock production with the consequent emission of gases such as methane and the burning used in agriculture and forest clearing, which release carbon dioxide. The causes of soil pollution: the excessive use of fertilizers and pesticides in agriculture and livestock; industries that pollute the soil, such as oil refineries, chemical, tanning and textile factories and open-air garbage disposal. The causes of water pollution: waste discharges from the sewage and sanitation system that are not properly treated; the deposit of garbage in rivers, seas and oceans; oil spillage and contamination of underground water with chemical and toxic products.
Curiosities, games, challenges and quiz about Ozone
Ozone is a gas composed of molecules with three atoms of oxygen (O3). This gas is distributed in the troposphere, which concentrates about 10% of all ozone, and in the stratosphere, which accumulates most of this gas, about 90%. Ozone found in the troposphere originates from pollutants released into the lower layer of the atmosphere. Ozone present in the stratosphere plays a fundamental role in maintaining life on planet Earth. Distributed in a thin and unstable layer in the stratosphere, between 25 and 30 kilometers from planet Earth, this gas absorbs more than 95% of the dangerous ultraviolet rays emitted by the sun, protecting the Earth from overexposure to these rays, which could affect the entire environmental dynamics of the planet. This decrease in the concentration of O3 in the atmosphere has caused an increase in the amount of ultraviolet rays that reach the earth's surface, causing various impacts to the environment around the world.

Origin of Oxygen to Human Impact
The oxygen generated by these living beings slowly accumulated in the atmosphere, which changed its composition and created, around 400 million years ago, the conditions necessary for the formation of an ozone layer. This layer is capable of filtering ultraviolet radiation, thus allowing living beings to colonize terrestrial environments outside of water. The enrichment of the atmosphere with oxygen, produced in photosynthesis, allowed this gas to become available and be used by living beings in cellular respiration, which in turn releases the carbon dioxide consumed in photosynthesis into the atmosphere. The Earth's atmosphere has undergone continuous changes in its composition over geological time, responsible for drastic climate changes and mass extinctions. Currently, it is human activities that produce a growing and global impact on the atmosphere with consequences that are still difficult to predict.Evolution of the Atmosphere
The Earth was an uninhabitable place with no breathable air for hundreds of millions of years after its formation. Over time, however, it developed an atmosphere that was quite different from the one we know today. The primitive atmosphere was composed of methane, ammonia, hydrogen, nitrogen, carbon dioxide and water vapour, but there was no oxygen. Oxygen only appeared in the atmosphere due to its release by living beings, namely through photosynthesis. The first photosynthetic beings were not plants or algae, as they did not yet exist. The first living beings to carry out photosynthesis and release oxygen into the atmosphere were microorganisms similar to today's bacteria that began to appear in the primitive oceans, more than 3,000 million years ago.The Importance of the Atmosphere for Life
Atmosphere: The atmosphere plays crucial roles in sustaining life, such as filtering harmful ultraviolet rays through the ozone layer , protecting against meteorite impacts , and regulating the environmental temperature compatible with life through the greenhouse effect . These characteristics help create suitable conditions for life. The existence of the atmosphere is possible due to the size and mass of the Earth, which generate sufficient gravitational attraction to keep this layer of gases attached to its surface. Without this gravitational force, the atmosphere would disperse into space.publicity
Essential Elements for Life on Earth
Geosphere dynamics: The movement of tectonic plates and the rock cycle are processes that shape landscapes, form soils and create new environments, driving the evolution and diversity of species. Water: The abundance of liquid water is essential for life, as it makes up between 70% and 90% of the body weight of living beings and participates in all their vital processes. Natural environments: The variety of habitats on Earth favors the capacity for adaptation and the growth of biodiversity, increasing the chances of survival and continuity of species.The Influence of the Moon and the Giant Planets
The Moon and the giant planets: The movement of the Moon around the Earth helps to stabilize the axis of rotation, maintaining a constant tilt, which is crucial for the cycle of the seasons . In addition, the gravitational force of the Moon is responsible for the occurrence of tides and ocean currents , which influence the Earth's climate . The gravity of the giant planets, especially Jupiter, attracts asteroids and comets that could collide with the Earth and cause extinctions . Earth's magnetic field: This field acts as a protective shield, deflecting much of the harmful radiation emitted by the Sun.Essential conditions for life on Earth
Earth is the only planet in the Solar System that has the ideal conditions for life as we know it. Some of the factors that make this possible include: the perfect distance from the Sun, the influence of the Moon and the giant planets, the presence of a magnetic field, the dynamism of the geosphere, the abundance of water, the diversity of natural environments and a protective atmosphere. Distance from the Sun: Earth orbits within the habitable zone of the Solar System, at a distance that allows the presence of liquid water on its surface.publicity
The Origin of the Conditions for Life
Some important events in Earth's history that created the conditions for the emergence of life over thousands of years include: the formation of the planet with impacts from other bodies in the Solar System; the creation of a solid crust, with continents and oceans; the development of an atmosphere with a greenhouse effect; the movement of tectonic plates and volcanic activity; atmospheric electrical phenomena; the formation of simple organic molecules and macromolecules; the emergence of the first primitive cells; the beginning of photosynthesis and the production of oxygen; the creation of the ozone layer and superglaciations that gave rise to new environments.Planet Earth
Earth is a unique and extraordinary planet, being the common home of all species, where we still enjoy the best conditions of comfort, sustenance and protection for life. However, it was not always like this. The planet we know today is the result of a complex process of transformations that began about 4.6 billion years ago. With the advancement of science and technology, human intelligence has made our species the most dominant, capable of influencing natural processes, consuming large amounts of resources and, thus, shaping the future of the planet. Now, we have the responsibility to ensure the survival of all the species that share the Earth with us.Curiosities, games, challenges and quiz about The
The discovery of penicillin: a revolution in medicine. In 1929, by a stroke of luck, Alexander Fleming found the first antibiotic, penicillin. During World War II, its potential was extensively tested, saving countless lives. Noel Rosa and many other artists could have been saved from tuberculosis if this discovery had occurred earlier.
The curious thing is that Fleming, a researcher dedicated to bacteria, left a culture plate forgotten during the summer. By chance, some bread crumbs fell on it, creating fungus. When his colleague Merlin Pryce noticed something strange in the plates about to be discarded, Fleming realized that the fungi had eliminated the bacteria, giving rise to penicillin, a milestone in the history of medicine.publicity
Curiosities, games, challenges and quiz about Rocks
Rocks are natural formations composed of cohesive minerals, resulting from geological processes. Minerals, in turn, are solid inorganic substances, with a crystalline structure and defined chemical composition. Unlike organic components, minerals have an ordered arrangement and can form crystals visible to the naked eye, as in granite.Curiosities, games, challenges and quiz about Natural Sciences is short for Biology
Natural Sciences is short for Biology, Physics, Chemistry and Geography, and its main areas of study are natural history, fundamental laws of nature, structural analysis of the Earth and the forces that control the interaction between organisms. In this course, students examine and study the elements of nature around them, addressing the environment, the life cycle and interactions between living beings. Other subjects addressed include climate change, biodiversity, ecosystems and human influences on nature.Curiosities, games, challenges and quiz about Reproduction
Reproduction is the function that allows the continuity of life and is common to all living beings. In humans, reproduction is sexual, as it is possible by the union of two sex cells: one female, the oocyte, and the other male, the sperm. When the human being is born, we can only identify the sex of the baby by observing its genitals. Thus, we call these organs primary sexual characters – the penis and the vagina. As we grow, our body undergoes changes in its external appearance – secondary sexual characteristics – which in adolescence already allow us to distinguish between girls and boys.publicity
Curiosities, games, challenges and quiz about Adolescence
Adolescence begins with puberty - from 8 to 14 years old, in girls, and from 9 to 15 years old, in boys. This is the phase in which not only major physical changes occur, but also psychological and even relational changes. In this phase, the "chemical messengers" - the hormones testosterone, in boys, and estrogen and progesterone, in girls -, which were inhibited in childhood, trigger the appearance of secondary sexual characteristics, giving human beings the physical traits they will have in adult life. Sometimes during adolescence, pimples appear on the face. This inflammation and obstruction of the pores of the skin, called acne, is caused by an increased production of sebum (fat) from the sebaceous glands of the skin, due to intense hormonal activity.Curiosities, games, challenges and quiz about The
The male reproductive system consists of: the testes, the vas deferens, the seminal vesicles, the prostate and the penis. Starting at puberty, the testes continually produce millions of sperm, the male sex cells. The sperm, together with a fluid from the seminal vesicles and the prostate, form the sperm. The emission of this liquid to the outside of the body is called ejaculation. Seminal vesicles (Produce a viscous fluid); Prostate (Produces the milky and thick liquid that mixes with the seminal fluid, providing the nutritive and transport medium for the sperm); Deferent ducts (carry sperm from the testicles to the penis) Urethra (Channel common to the reproductive and urinary systems); Scrotum (skin pouch that surrounds the testicles); Penis (Organ that conducts sperm to the outside) and Testicles (Located outside the body, inside a bag, the scrotum. They produce sperm).Curiosities, games, challenges and quiz about The female reproductive system
The female reproductive system is made up of: the ovaries, the fallopian tubes, the uterus, the vagina and the vulva. The ovaries produce the female sex cells called oocytes. The girl has the full amount of oocytes at birth and, as soon as she menstruates, she monthly releases one oocyte from each ovary, alternately. Uterus (muscular organ, hollow, in the shape of an inverted pear and with very elastic walls where the new being will develop. The lower part is called the cervix); Fallopian tubes (Two channels through which the ovaries communicate with the uterus); Ovaries (They are about the size of an almond. Their function is to produce oocytes) and the Vagina (It forms the connection between the uterus and the outside and its walls are elastic and muscular).publicity
Curiosities, games, challenges and quiz about In a flowering plant reproduction
In a flowering plant reproduction is sexual and is carried out by seeds. The flower is the organ responsible for the reproduction of the plant. Its various constituents have different and specific functions that, together, allow the reproduction of the plant, that is, allow the joining of female and male sex cells to give rise to the egg or zygote, the first cell of the new being. Support organs (The receptacle and the peduncle support the entire flower); Protective organs (The corolla - set of petals and the calyx - set of sepals, protect the reproductive organs); Reproductive organs (The carpels - set of female organs and the stamens - set of male organs, are responsible for plant reproduction); the Anthers (they are made up of small sacs full of pollen grains that give rise to male sex cells. The oosphere, the female sex cell, is located in the ovaries).Curiosities, games, challenges and quiz about The
The transfer of pollen grains from the anthers to the stigma of the same or another flower is called Pollination, which allows the meeting between the male sex cell and the female sex cell. Pollination agents are responsible for transporting pollen grains from the stamens of a flower to the stigma of the same flower, or from one flower to another. Without these, the pollen grains would have difficulty reaching their destination and reproduction might not occur. Insects, wind, some mammals and birds, water and man are examples of pollination agents. Pollination can be direct (by self-pollination) or indirect (by crossing with another flower of the same plant or with flowers of different plants of the same species). Direct pollination (Pollen from a flower lands directly on the stigma of that same flower) and Indirect pollination/9 Pollen from a flower lands on the stigma of another flower on the same plant or on a different plant).Curiosities, games, challenges and quiz about The process of seed dispersal
The process of seed dispersal is called dissemination. This process is extremely important for the seeds to be taken to other places, often far from the plant that originated them, and thus be able to colonize new environments. Dissemination can be carried out: by animals (including humans), by wind, water and by the plant itself (mechanical dissemination). When it finds a place with adequate temperature, humidity and light conditions, germination takes place, that is, the seed becomes a new plant. In the seed, there are specific structures that will give rise to the various organs of the future plant: the radicle (will give rise to the root of the plant), the caulicle (will become the stem of the plant), the bud or plumule (from which the first leaves of the plant). The cotyledons (contain food reserves, which the embryo needs) and the integument (protects the entire seed).publicity
Curiosities, games, challenges and quiz about Microorganisms
Microorganisms are organisms so small that they are invisible to the naked eye and can only be observed with the help of a microscope. Micro-organisms exist in the most varied habitats: in the air, soil, water, inside our bodies or on the walls of our homes, for example. To develop they need adequate conditions of humidity, temperature, oxygen and nutrients. We can identify several groups of micro-organisms: Protozoa (Trypanosoma brucei - sleeping sickness); Bacteria (Escherichia coli); Viruses(Ebola Virus) and Microscopic Fungi(Mold Fungus). Important micro-organisms for humans: Pathogenic microorganisms (they cause diseases such as flu, pneumonia, athlete's foot and sleeping sickness) and Useful micro-organisms (they are useful in the daily life of human beings, for example, the yeasts that we use to make bread or the bacteria in yogurt).Curiosities, games, challenges and quiz about Louis Pasteur (1822-1895)

Curiosities, games, challenges and quiz about With
With the development of societies and technology, new threats to the planet also arise. Thinking he is doing his best, man is destroying his home, the Earth, polluting the soil, air and water. The main causes of air pollution are: the burning of fossil fuels; agriculture and livestock production with the consequent emission of gases such as methane and the burning used in agriculture and forest clearing, which release carbon dioxide. The causes of soil pollution: the excessive use of fertilizers and pesticides in agriculture and livestock; industries that pollute the soil, such as oil refineries, chemical, tanning and textile factories and open-air garbage disposal. The causes of water pollution: waste discharges from the sewage and sanitation system that are not properly treated; the deposit of garbage in rivers, seas and oceans; oil spillage and contamination of underground water with chemical and toxic products.Curiosities, games, challenges and quiz about Ozone
Ozone is a gas composed of molecules with three atoms of oxygen (O3). This gas is distributed in the troposphere, which concentrates about 10% of all ozone, and in the stratosphere, which accumulates most of this gas, about 90%. Ozone found in the troposphere originates from pollutants released into the lower layer of the atmosphere. Ozone present in the stratosphere plays a fundamental role in maintaining life on planet Earth. Distributed in a thin and unstable layer in the stratosphere, between 25 and 30 kilometers from planet Earth, this gas absorbs more than 95% of the dangerous ultraviolet rays emitted by the sun, protecting the Earth from overexposure to these rays, which could affect the entire environmental dynamics of the planet. This decrease in the concentration of O3 in the atmosphere has caused an increase in the amount of ultraviolet rays that reach the earth's surface, causing various impacts to the environment around the world.Curiosities, games, challenges and quiz about The digestive system
The digestive system is made up of organs that work together to allow the absorption of as many nutrients as possible from the food ingested. It is formed by the following organs: mouth, pharynx, esophagus, stomach, small intestine, large intestine and anus. In addition, it is connected to glands that release their secretion inside the digestive tract, they are: salivary glands, pancreas, liver and gallbladder.publicity
