Likurg_2 [28]

Answer:

Processing and storing food.

Explanation:

The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.

The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.

The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.

Thus, Processing and storing food is correct.

In cases of low body fat levels (i.e. in athletic women), there will be relative amenorrhea because of the suppression of the follicle-stimulating hormone and the luteinizing hormone leading to a type of amenorrhea called athletic amenorrhea.
