Which form of natural selection does the graph represent? A graph has trait value on the horizontal axis and proportion of indiv
iogann1982 [59]

Answer:

directional selection

Explanation:

Directional selection is the most common type of natural selection and occurs when some individuals with characteristics favorable to the conditions of the environment in which they live, have survival advantages over individuals who do not have this advantage, who end up dying.

Imagine, for example, a graph showing the directional selection in the same species of moths. Moths of the same species have white and brown collations, in summer, brown moths can camouflage themselves on tree trunks, while white moths cannot and are easily captured by their predators, which means that the amount of white moths decrease.  In this graph, the population of white moths would be at a minimum, at the same time that the population of brown moths would be at maximum.

However, with the arrival of the reverse, snow begins to cover the trees, allowing white moths to camouflage themselves more easily. The brown moths, then, are very exposed to predators, causing their population to reach the minimum while the population of white moths reaches the maximum.

EleoNora [17]

Answer:

Hi there, the answer is energy

Explanation:

Carbon dioxide, oxygen, and water are all products of cellular respiration in fact carbon dioxide and oxygen are extremely important for ATP. If you are talking about aerobic respiration oxygen is the main product for it because it reacts to glucose. The only thing that isnt part of the product of cellular respiration is energy. After ATP is created for the plants it makes its own energy afterward.
