Answer: Phospholipids have hydrophobic (water fearing) tails which face each other to form the core of the bilayer while their polar (hydrophilic) head groups face outward.
Explanation: Phospholipids are components of cell membrane. Phospholipids are made up of two parts: the polar (hydrophilic) head group and the nonpolar (hydrophobic) tail. The non polar tails of the Phospholipids are water fearing while the polar head groups are water loving, therefore when phospholipids are mixed with water the hydrophobic tails arrange themselves in a way that they will not come in contact with water molecules. The hydrophobic regions of the lipids face each other forming the interior of the bilayer while the polar head groups face outwards interacting with the surrounding water.

Complete Question:
Cortisol is a hormone produced in response to stress, including starvation, in humans. Which of the following is most likely an immediate effect of a starvation-induced increase in cortisol secretion?
(A) Increased activation of the immune system
(B) Increased urine production by the kidneys
(C) Increased bone and collagen formation
(D) Increased mobilization of fatty acids from fat cells
Answer: Increased mobilization of fatty acids from fat cells.
Explanation: Cortisol is a hormone produced in response to stress, including starvation, in humans. Immediate effect of a starvation-induced increase in cortisol secretion is the increased mobilization of fatty acids from fat cells (Adipose tissue).
Starvation occurs when an animal doesn't feed due to unavailability of food. The body system makes use of stored glycogen which is synthesized to glucose by hormonal secretion of glucagon by the pancreas.
However, when the glucose converted is finished. Cortisol is secreted, which then initiate the mobilization of fatty acids as source of energy from the adipose tissues (fat cells) in the body system.
