Question

A biologist is studying a structure that is made up of two layers of phospholipids. What is she most likely studying?

DNA molecules
cell membranes
fats
wax

Answer 1

She is studying CELL MEMBRANES which consist of a lipid bilayer and may consist of a third outer layer of cell markers in the form of carbohydrate chains that attach to protein to form glycoprotein or attach to the lipid to form glycolipid.

Answer 2

The correct answer is the option: cell membranes.

Step-by-step explanation:

Hello! Let's solve this!

The researcher is studying a phospholipid bilayer, the function is to allow some substances to enter and others not to the cell. This phospholipid bilayer is the cell membrane. It has a hydrophilic part and a hydrophobic part.

We conclude that the correct answer is the option: cell membranes.
