It has been discovered that many plants synthesize molecules that destroy the corpora allata, which are the structures responsible for synthesis of juvenile hormone. insects exposed to these molecules do not molt. which statement reflects how levels of juvenile hormone disrupt the insect life cycle?
a) reduced juvenile hormone prevents molting.
b) exposure to juvenile hormone prevents the larvae from developing into adult insects.
c) reduced juvenile hormone causes insects to molt prematurely into sterile adults.
d) exposure to juvenile hormone causes juvenile insects to die.

B) Exposure to juvenile hormone prevents the larvae from developing into adult insects.

Explanation:

Given that, Plants synthesize(i.e plant produce a combination of elements) molecules that destroy the corpora allata. The corpora allata are structure responsible  for synthesis (production) of Juvenile hormone.

This implies that, Plant produces molecules that destroy the structure responsible for the production of Juvenile hormone.

If we proceed, the question continues by saying Insect exposed to these molecules do not molt.(i.e insect exposed to these molecule do not change in  growth)

What is molting?

Molting often called (ecdysis) is the phase of growth and development in insect that comprises of two main activities which are shedding and replacement of their culticular exoskeleton layer in order to make way for new growth and new stage of an insect.

Therefore from the aforementioned, the best statement that reflects how levels of juvenile hormones disrupt the insect liffe cycle is that : Exposure to juvenile hormone prevents the larvae from developing into adult insects.
