Insects such as mosquitoes and beetles can beat their wings at tremendous speeds. This can be accomplished because
A. their wing muscle contractions causes another set of muscles to stretch which in turn produces another contraction without waiting for the arrival of a nerve impulse.
B. their wing muscle contractions cause another set of muscles to relax which in turn produces another wing movement.
C. their wing muscle contractions are stimulated by the continuous nerve signal impulses which produce a continuous contraction of their wing muscles.
D. their wing muscle contractions are capable of producing more ATP which allows these insects to have much faster and sustained wing movements.
E. their wing muscle contractions produce nerve impulses which lead to more contraction of the wing muscles which in turn permits faster motion of the wings.
A. their wing muscle contractions causes another set of muscles to stretch which in turn produces another contraction without waiting for the arrival of a nerve impulse.
