Answer:

To a 1st Grader:  

Carbon is the magic element that is the basis of life on Earth. All living things contain carbon. Animals breathe it out, and plants breathe it in. Plants, people and animals depend on each other.

The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Plants take carbon dioxide from the air along with water and photosynthesis from the sun and use it to make food.

Explanation:

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.  To a first grader is different because they wouldn't understand what half of these words mean lol.

Which type of natural selection occurs when an intermediate phenotype is favored?
klasskru [66]

Answer:

The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.

Explanation:

There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.

A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.

A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.

The extinction of snakes from the population will lead to decrease in genetic variation.
