Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

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.
