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 have trouble with respiration and circulation, due to impaired muscle function.
B) The mosquito would develop a weakened exoskeleton that would make it vulnerable to trauma.
C) The mosquito wouldn't be affected at all.
D) The mosquito would have trouble digesting food, due to impaired gut function.

Endodermal cells are the cells that differentiate into the gut or digestive tract of an organism. Therefore, inhibiting their development would result in impaired gut function, which would make it difficult for the mosquito to digest food. This would likely lead to reduced growth and ultimately death.
