The correct answer is "atrial natriuretic peptide" or "ANP". ANP is secreted by the the atria and the muscle cells of the heart. ANP primarily functions to increase sodium excretion (hence the term natriuretic) which facilitates osmotic diuresis, since there will be a high amount of solute in the renal tubules, this will exert an osmotic force that draws water and facilitate diuresis. This will eventually result to increased urinary output and dehydration.
They all require oxygen for respiration. All cells must go through cellular respiration.
Answer:
C
Explanation:
The correct answer would be that <u>in science, a theory is well supported by observations and/or experimental data.</u>
<em>Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.</em>
<em>Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.</em>
