The drawing below illustrates a small portion of the molecules that make up a cell membrane. What is the primary function of the
phospholipid in the cell membrane? a. line up amino acids for protein synthesis b. prevent the passage of certain molecules into the cell c. helps cells recognize each other d. allow glucose molecules into the cell
Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.
In general, pseudoscience is based on "<span>static information that does not change" because this kind of fake science doesn't change when new evidence is brought into light. </span>
Polystyrene is a good insulator as it has small air bubbles trapped inside of it. This means heat energy cannot flow through them therefore it is an effective material for keeping honeybees warm in the winter. Hope this helps :)
