Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
Answer:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.

Describe the effect succession has on genetic diversity
Answer:
Dispersal fundamentally influences spatial population dynamics but little is known about dispersal variation in landscapes where spatial heterogeneity is generated predominantly by disturbance and succession. We tested the hypothesis that habitat succession following fire inhibits dispersal, leading to declines over time in genetic diversity in the early successional gecko Nephrurus stellatus.
Explanation:
Answer:
There are five main elements to ecological succession: primary succession, secondary succession, pioneer and niche species, climax communities and sub-climax communities.
Primary Succession. ...
Secondary Succession. ...
Pioneer and Niche Species. ...
Climax Communities. ...
Sub-climax Communities. while Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments.

Why would losing just a few dozen aquatic species lead to the end of life in the ocean as we know it?
I NEED THE ANSWER BEFORE 11:59!!!!
First one gets brainiest
Answer: It would unbalance the ecosystem.
Due to the fact that if some species die off, the other species that rely on those species for food or protection would loose that food/ protection which may lead to their extinction and their extinction would lead to another extinction and so on.

Answer: No
Explanation:
DNA is a molecule that carries genetic materials in all living things. Amino acid on the other hand are the monomers that make up the proteins
Select one of the organisms to go 'extinct' or become 'endangered' from the food web shown in the diagram. Tell how the change or loss of the organism will likely affect other organisms and the environment of the ecosystem.
Please help
Answer and Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes the food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.
In the exposed example, if salmon gets extinct, the krill population will increase because they won´t be eaten by salmon. As the krill population goes up, phytoplankton will decrease, because more krill will be eating these organisms.
As salmon disappears, the cephalopod population will be affected, because salmon was one of its food sources. As cephalopods are also eaten by the puffins, these last animals will also be affected. The decrease in puffins population means that the rats' population will decrease too, as rats feed on the puffin´s eggs of puffins. Finally, foxes will be affected too, because rat´s population went down.
This is only one path affected by the extinction of the salmon. But all the animals in the trophic chain will be affected.
Answer:
Phytoplanktons.
Explanation:
This is the primary producers in this ecosystem.Its extinction will affect photosynthesis, and therefore oxygen and carbon availability for the survival of other organisms in the ecosystem.
Besides this, it is the primary producers for zooplanktons, sandlance, and krills of the food web.Therefore, its extinction affects the survival and the population of these consumers.
Consequently, Salmon, puffin, and Cepahlopods which depended on the above three primary consumers fizzled out of the foodweb.
Eventually,rats,kitiwake,,gull auklet population disappear with consequent reduction in the numbers of Fox.
How does negative feedback control hormone levels? **EXTRA POINTS**
Answer:
Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance. In this way, the concentration of hormones in blood is maintained within a narrow range.

There are developmental differences in the amount of gray matter in children. For example, around the ages of _____, the volume of gray matter in the caudate, a part of the basal ganglia involved in control of movement and muscle tone, peaks.
Answer:
7 in girls and age 10 in boys
Explanation:
Around the ages of 7 in girls and age 10 in boys, the volume of gray matter in the caudate, a part of the basal ganglia involved in control of movement and muscle tone, peaks. This is one of the reasons as to why girls are more athletic and flexible earlier when compared to boys who develop more muscle tone later on in life.
Why is it necessary to convert carbohydrates into sugars? So they can be absorbed by the body Because sugars taste better than carbohydrates The body cannot get sugars from other sources Chemical energy is only found in sugars
Answer:
So that they can be absorbed by the body.
Explanation:
Carbohydrates are complex and sugars are simple form of carbohydrates. Since carbohydrates is complex and not easily absorbed it is converted to sugars which the body can absorbed easily during digestion and it is converted to energy to drive the cells. Examples of sugars are sucrose,glucose.
During ages six to eleven, Freud's latency period, what do experts believe happens to the libido? A.That it is channeled into self-development B.That it is only seen in small, private groups with peers C.That it is displayed out in the open, the same as in earlier ages D.That it is hidden since most children of that age bathe and get dressed alone
Answer: A.That it is channeled into self-development
Explanation:
During the latency stage, libido is in the “do not disturb mode.” According to Freud, it is a period when sexual energy is being channeled to activities like hobbies, learning, and building social relationships.
He felt that at this stage, people develop healthy communication and social skills and the failure to move through this stage can lead to lifelong immaturity, or inability to have and maintain a healthy, happy, and fulfilling sexual and non sexual relationships when one becomes an adult.
