Answer:
b. Aldosterone promotes sodium reabsorption in the kidneys.
Explanation:
Once it is produced by the adrenal gland it stimulates the mineralocorticoid receptors on the distal tubule and collecting duct of the kidney's nephrons. This causes sodium reabsorption in the kidneys indirectly affecting water retention.

Answer:
C - Contains the embryonic disk
Explanation:
After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.
On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.
As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.
The embryonic disc develops into 3 layers:
There is a major differentiation of cells which gives a template  for the origin of development of specific organs of the embryo.
