In this kind of population, the make up of the population's gene pool will remain virtually the same as long as these conditions hold. In this kind of situation, no evolution can take place, all thing will remain the same. For evolution to occur, competition must exist.
Animal plays important role in angiosperm reproduction either by visiting flowers for the process of pollination or eating fruits which aids in continuation of generation
D. A variable or alteration to one part that affects an entire system

Answer:
<h2>A
</h2>
Explanation:
1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.
2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.
3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around 100 molecules of glucose. These fibers cluster into bundles, known as or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as in which orientation cellulose is deposited in the cell wall.
The characteristic best distinguishes glycolysis and the Krebs cycle from the electron transport chain is the amount of ATP produced . In glycolysis net ATp production is 2 ATP and in 1 Kreb's cycle 38 ATP are produced. Hence option A is correct.
