Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
Holding your breath while ascending can lead to all of the above options.
Surfacing excessively fast or holding the breathing while swimming to the surface can make the air in the lungs expand which is known as pneumonic barotrauma. This might break lung tissue, which can prompt gas bubbles to be delivered into the blood vessel dissemination (arterial gas embolism).
The air in the lungs becomes risky when an individual ascends. On the off chance that somebody holds their breath while rising to the surface, the lungs and the air inside them extend as the water pressure decreases. Since that air has no place to escape, it continues to expand against the walls of the lungs, no matter what the organ's capacity.

Answer:
B. 50%
Explanation:
The yellow trait is dominant (uppercase Y), so the heterozygous pairs (Yy) as well as the homozygous dominant pairs (YY) would be yellow. There are 2 pairs of Yy there for 50% of the offspring would have a yellow pod.
