Suppose a researcher for a pest-control company developed a chemical that inhibited the development of an embryonic mosquito's endodermal cells. Which of the following would be a likely mechanism by which this pesticide works?

A. The mosquito would develop a weakened exoskeleton that would make it vulnerable to trauma.

B. The mosquito would have trouble digesting food, due to impaired gut function.

C. The mosquito would have trouble with respiration and circulation, due to impaired muscle function.

D. The mosquito wouldn't be affected at all.

The mosquito would have trouble digesting food, due to impaired gut function would be a likely mechanism by which the pesticide works.

Option: (B)

Explanation:

Endodermal cells are present in both diploblasts and triploblasts. Endoderm is an embryonic germ layer which gives growth to tissues that forms organs and internal structures. The 'endoderm' is found in both 'vertebrates and invertebrate embryos' and are responsible for the 'formation of the gut' and associated organs. Hence, the chemical which prevent from the formation of endodermal cell in an mosquitoes will affects its gut functions.
