The Greenhouse Effect is Earth's way of keeping its temperature constant. The atmosphere is highly transparent to sunlight, but about 35% of the radiation we receive will be reflected back into space, with the remaining 65% trapped on Earth. This is mainly due to the effect on the infrared rays of gases such as carbon dioxide, methane, nitrogen oxides and ozone present in the atmosphere (totaling less than 1% of this), which will retain this radiation on earth, allowing us to watch their calorific effect.
Liquid water occupies oceans, lakes, rivers, dams, etc. Continuously and slowly, at room temperature, evaporation occurs, that is, water changes from liquid to gaseous state. The larger the surface area of water exposure (eg an ocean or tree leaves in a forest), the higher the evaporation level.
It is an inflammation in the liver that can be caused by various types of viruses. The symptoms are similar to those of the flu and there is also jaundice (yellowish discoloration of the skin caused by the deposit of a substance produced by the liver). The person needs to be at rest and follow the medical guidelines.
If the person often goes to the bathroom and the stools come out liquid or very soft, they may have diarrhea. Diarrhea can be caused by microbes acquired from contaminated food or water. Mild diarrhea almost always ends on its own. However, you need to drink fluids to avoid dehydration, which is very dangerous.
The water may contain clay, sand and other impurities. A major danger of water contamination is, for example, the presence of toxic chemicals or microorganisms that make water polluted. There are several sources of pollution, as we will see below. The consequence of the lack of sewage treatment The large number of waste from the populous residential nuclei, discharged into streams, rivers and seas, causes pollution and water contamination.
Genital condyloma is a lesion in the genital region caused by the Human Papillomavirus (HPV). The disease is also known as rooster crest, fig tree or crested horse. HPV causes cauliflower-like warts of varying sizes on the genitals. It may also be related to the appearance of some cancers, especially in the cervix, but also in the penis or anus.
Infectious disease that is characterized by the presence of abundant purulent discharge (discharge) from the urethra in men and vagina and / or urethra in women. This condition is often preceded by itching (itching) in the urethra and burning urination. In some cases, general symptoms such as fever may occur.
The passages between the three physical states (solid, liquid and gaseous) are called physical state changes. Look at the following diagram and then read the explanations of each of these changes. Have you ever seen how on a hot day a piece of ice melts right out of the freezer? In this case, the solid state water quickly changes to the liquid state.
The following table summarizes the main sexually transmitted diseases. The causative agent, symptoms and prevention modes are listed. Diseases Causing Agent Symptoms Prevention Condyloma acuminata (rooster crest) HPV Formation of warts in the anogenital or cervical region Avoid contact with contaminated persons; use a condom.
Oral Combined Hormonal Contraceptive (AHCO) AHCO is the use of progesterone-associated estrogen, preventing conception by inhibiting ovulation by blocking the release of gonadotropins through the pituitary gland. It also modifies cervical mucus making it hostile to sperm, alters endometrial conditions, modifies tube contractility, interfering with ovular transport.
Do you know what those bubbles that appear in soft drinks are made of? Of carbon dioxide. And carbon dioxide is also the bubbles that come off in effervescent tablets. Carbon dioxide makes up only 0.03% of air. It appears in the atmosphere as a result of the breathing of living beings and combustion.
Air pollution is defined as the degradation of air quality as a result of direct or indirect activities that: Impair the health, safety and well-being of the population; create adverse conditions for social and economic activities; unfavorably affect the biota (living organisms); affect the aesthetic or sanitary conditions of the environment; release materials or energy in violation of environmental standards set forth in federal laws (Federal Law No. 6938 of 31 August 1981, governed by Decree 88 351/83).
Radio, television, newspapers and websites daily announce the weather forecast. Within a certain safety margin we know if it will rain, if it will be cold or hot. To facilitate the study of the atmosphere, scientists divide it into several layers. Troposphere The troposphere is the closest layer to the earth's surface.
Air mass is an air mass under certain conditions of temperature, humidity and pressure. The air masses may be hot or cold. Hot ones generally move from tropical regions, and cold ones originate from the polar regions. Air masses can be parked at a particular location for days and even weeks.
The amount of rain is measured by the rain gauge. In this device, rain is collected by a funnel on top of a drum and measured in a graduated cylinder. The amount of rainfall is measured in the rain gauge in millimeters: one millimeter of rain corresponds to 1 liter of water per square meter. When it is said, for example, that yesterday the rainfall, or rainfall, was 5 millimeters in the city of Porto Alegre, it means that if the rainwater had been collected in a swimming pool or any closed container, a layer would have formed. 5 mm high.
Thanks to the greenhouse effect, the temperature of the earth remains on average around 15ºC, which is favorable to life on the planet. Without this warming our planet would be very cold. The name greenhouse comes from glass greenhouses, where certain plants are grown, and sunlight passes through the glass warming the interior of the environment.
In other words, a biome is made up of all living beings in a given region, whose vegetation has much similarity and continuity, with a more or less uniform climate, and a common history in its formation. That is why all their biological diversity is also very similar. Brazil has a huge territorial extension and presents very varied climates and soils.
"Lung of the World," "Planet Water," "Green Hell," are some of the world's buzzwords about the Amazon. It is always in evidence anywhere in the globalized village. It interests everyone. One of the last regions of the planet that still seduces by the exuberance of a primitive nature, today absolutely threatened by its devastation.
Predator is the individual who hunts and devours another, called prey, belonging to a different species. Predators are generally larger and less numerous than their prey, being exemplified by carnivorous animals. Both predatory and prey populations generally do not go extinct or overpopulate, remaining in equilibrium in the ecosystem.
It is the inharmonious intraspecific relationship between individuals of the same species when they compete for the same environmental factors, especially space and food. This relationship determines the density of the populations involved. Cannibalism Cannibalism is the individual who kills and eats another of the same species. Occurs with scorpions, spiders, fish, planarians, rodents, etc.
The biosphere refers to the region of the planet occupied by living things. Life can be found in every region of the planet, however hot or cold it may be. The biosphere concept was created by analogy with other concepts used to designate part of our planet. Thus we can say that the boundaries of the biosphere extend from the high mountains to the depths of the abyssal marine pits.
