The evolutionary effects of the genetic drift are the greatest when the population is small.
In small populations, genetic drift can significantly change the frequencies of the alleles and affect the genetic structure of the population. In big populations, the effects of the genetic drift are small and insignificant.

Answer:
<h2>The source rock is the rock that contains the kerogen that the oil and gas forms from. The reservoir rock is the porous, permeable Rock layer or layers that hold the oil and gas. This migration occurs because oil and gas are less than than water.</h2>
mostly collagen and some calcium phosphate
<u>Answer:</u>
<em>A plasma membrane is the cellular structure that makes it possible for a cell to differ structurally and biochemically from its surroundings. </em>
<u>Explanation:</u>
<em>Plasma membrane</em> is the surrounding of all the cells. The function of plasma membrane in a cell is to regulate the incoming and outgoing elements from the cell.
<em>Phospholipid bilayer</em> is the main composition of plasma membrane. It makes the cell different from each other structurally as well as makes the cell different in <em>chemical composition </em>too.
