The tail of a male peacock is actually not very good for their survival: it makes them more visible to predators and makes other actions harder.
If the females no longer prefer such tails, other peacocks will have a better chance of mating with the females, because they generally have better chances for survival.
Therefore, the trait would gradually dissappear, and other traits (preferred by females or contributing to survival) would appear instead.
B. The coded blueprints for life
Answer:
The polar head groups of phospholipids interact with water while the hydrophobic hydrocarbon tails are packed away from the water.
Explanation:
A phospholipid contains glycerol to which hydrocarbon tails are bonded. These hydrocarbon tails make the hydrophobic region of the phospholipids and are packed away from the water to make the inner core of the membranes. Glycerol of a phospholipid also has a phosphate group attached to its third carbon. The phosphate and glycerol moiety together make the hydrophilic head part of the phospholipid and interact with the surrounding water.
