Question

An increase in the level of hormone A causes an
increase in the level of hormone B. The increase
in the level of hormone B then causes a decrease
in the level of hormone A. This process is an
example of
(1) a failure to maintain homeostasis
(2) the breakdown of chemicals
(3) a disruption in cellular coordination

Answer 1

for me it's number 4 because it is the process through which the level of one substance influences the level of another substance.if a high level of one hormone may inhabit the production of another hormone.
