There are several mutations that benefit the organism.A well known example is the antibiotic resistance developed by bacteria, which aid in their survival even when they are exposed to a given antibiotic. A single gene mutation in wild almond trees resulted in a variety that no longer synthesizes amygdalin.
Answer:
The correct answer is b) "All of the above".
Explanation:
Nowadays it is known that the lipid bilayer of the cells is not static, actually, the modern Fluid-Mosaic membrane model establishes that the lipids move constantly within the lipid bilayer. The lipids are able to rotate within its axis, the lipids are able to movement laterally moving from one site to the other within the same plane, and also can move from a plane to the other plane in what is known as transverse "flip flop" movement.

Q1. The answer is <span>c. a mechanism of evolution.
</span>
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution.
Q2. The answer is c. interactions between individuals.
Organisms interact with other organisms or abiotic factors in some system. The interaction <span>between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.</span>
Answer:
As the beetles have a uniform distribution, at a carrying capacity of 14,600 beetles, there are about 128 beetles per hectare. Because 55 hectares are now unlivable, the carrying capacity would decrease by about 7,040 individuals (55 × 128).
Therefore, the carrying capacity of the ecosystem will be (old carrying capacity – decrease in carrying capacity) = (14,600 – 7,040) = 7,560 beetles.
