b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.

It would eventually go extinct. If you put a shark in a fresh water pond and it can't adapt to fresh water it will die.
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
