Its C, as in active transport the substance tends to move from a reigon of high concentration to a reigon of lower concentration, against the concentration gradient. for example: mineral salts from soil move by active transport to the root hair cell.
D is not the answer as water always moves by the process of osmosis.
i hope that helped (:
Answer:
Asexual Reproduction
Explanation:
Asexual Reproduction is a kind of reproduction that does not change the number of chromosomes or involves gamete fusion. Asexually reproduced organisms have the same genes as the parent organism. The process of asexual reproduction is usually an organism splitting itself to create what is basically a clone of itself.

Answer:
C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
Explanation:
The terminal part of distal convoluted tubules has two different types of cells: principal cells and intercalated cells. These cells are also present throughout the collecting duct. The principal cells serve to reabsorb Na+ and secrete K+ and have receptors for aldosterone and antidiuretic hormone (ADH).
The function of intercalated cells reabsorb HCO3 - and K+ and to secrete H+. Angiotensin II stimulates the adrenal cortex to release aldosterone which in turn stimulates the principal cells in the collecting ducts to reabsorb more Na+ and secrete more K+. The increased reabsorption of Na+ facilitates reabsorption of more water to increase blood volume and blood pressure.
The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
