The main molecules present in the plasma membrane are<em><u> phospholipids</u></em>, those molecules are made of a polar, hydrophil end(glycerol with a phosphate group attached) and two non-polar, hydrophobe ends(two fatty acids rests). The cell identity is determined by <u><em>proteins </em></u>present in the membrane, a  very important type of protein that determines the identity of a specific cell is called marker. The membrane fluidity is reduced by a lipid with a ring structure, <u><em>cholesterol</em></u>, this molecule belongs to a class of biomolecules called steroids.

Alborosie

Answer: 5

Explanation:

Since 1 out of 200 people carry the defective gene that causes inherited colon cancer.

In a sample of 1000 individuals, we say

1 = 200

y = 1000

cross multiply

y x 200 = 1000 x 1

200y = 1000

y = 1000/200

y = 5

Thus, in a sample of 1000 individuals, approximately 5 will be carriers
