What is the difference between the development patterns of a chicken and a monkey? a) a monkey develops gill arches while a chicken does not. b) a monkey develops a notochord while a chicken does not. c) a monkey develops an umbilicus while a chicken does not. d) a monkey develops a shell breaker while a chicken does not.

The correct answer is option C which is, "A monkey develops an umbilicus while a chicken does not".

The umbilicus is the developmental organ in the mammals which is also known as umbilical cord.

This organ or structure is used to transfer the food and nutrition from mother to the developing embryo.

At the time of delivery this structure is also delivered out from the body of the mother.

Chicken does not have this structure because developing embryo get nutrition from the yolk sac.
