The oxygen-rich surface water blends with the deeper, depleted water. The dissolved oxygen concentration in the mix can be too low to support life in the pond. Both fish and plankton can die from low dissolved oxygen following a turnover. Thus, turnover can happen if a cold rain and wind cools the surface water.
ANSWER: ECDYSONE
EXPLANATION: Ecdysone is produced and released from the prothoracic gland located at the prothorax of the insects, which act mainly to stimulates molting or ecdysis (i.e ex-sheating of old cuticle) in insects.
Moreover, the release of ecdysone to trigger molting and metamorphosis, is stimulated by PTTH .
Furthermore, in cases where juvenile hormone is absent, an insect will still metamorphose into the adult form.
