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.
Mutualism interaction do both species benefit?
<span>The function of a cell wall has the same
function of the cell membrane; it protects the cell. Cell wall is made up of cellulose
that is only present in plant cells. Cellulose is a sugar that has a sheet like
structural carbohydrate. It is rigid that is used for support and provides protection
to the plant cell from damage. They cannot be dissolved in water. An example is
if you eat food that contains mostly of leaves. You will observe that you will
eliminate the same material as when you it. That is because our human body does
not have the enzyme that dissolves the cellulose.</span>

<u>Correct Option:</u>
<u>Organize seminars</u> to educate other students about the deteriorating environmental conditions and the steps needed to improve the area. Also, encourage other students to volunteer for workshops about <u>deforestation</u>.
<u>Option:</u> B and C respectively.
<u>Explanation:</u>
As the environmental conditions are deteriorating day by day, thus it is necessary to train to boost upcoming generation for preserving it in most appropriate manner. For such actions awareness is necessary which should be encouraged by some volunteers of non-profit organization, environment protecting units of state and central, etc to conduct seminar in colleges and schools for students to make them understand the need of plantation and disadvantages of deforestation. The pattern to aware them should be remarkable, in order to create huge impact on the new generations towards green land.
