Answer #1

1. why plasma membrane is called ' bilayer' ?

the bilayer is two thick layers of phospholipids arranged with its hydrophobic end directed towards the opposite side and the film and its hydrophilic end-directed outwards.so the correct option is a) there are two opposing layers of phospholipids in the membrane.

2. what part of phospholipid is non-polar?

there are two parts of the phospholipid molecule. first is polar phosphate head which is hydrophilic so they face outward and non-polar lipid tail which is hydrophobic so face inward. so correct option is a) lipid tail
