<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.
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
Genetic Diversity because someone can be the same species as you but they might look different because of their parents. The genes from the parents go to the kid.
