Answer:
D) Energy is required in order to maintain homeostasis--without a constant, organized internal state, the cell will die.
Explanation:
Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance.
Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping at an appropriate temperature (37º C) ensuring that the necessary changes to the body occur; and thus the cells of the body develop.
Because of homeostasis, cells need a constant supply of energy. That's because energy is needed to maintain homeostasis - without a constant, organized internal state, the cell will die.

The Tillite debris from melting glaciers, in Dwyka Tillite are located at the bottom layers of the Karoo Supergroup, which is an indication that millions of years ago, South Africa was under extensive glacier coverage formed during the movement of the continent past the South Pole
The eventual arrival of the continent to temperate regions away from the South Pole resulted in the melting of the glaciers from which a huge swamp was formed.
