Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

The answer is C, the membrane is in charge of what enters and leaves the cell
Answer: By losing its two outermost electron
Explanation:
Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.
Hence, to form an octet structure, it gives off its two electrons as shown below:
Ca <----> Ca2+ + 2e-
Thus, by losing its two outermost electrons, a positively charged calcium ion (Ca2+) is formed
<h2>Morphogenesis </h2>
Explanation:
Thalidomide are now not taken by women who are pregnant or who could become pregnant
Thalidomide was used as sedative by women in early 1960s and even a single dose of thalidomide taken during pregnancy can cause severe birth defects (physical problems present in the baby at birth) or death of the unborn baby
Morphogenesis is associated with development of shape and since use of thalidomide leads to limb and organ deformities, it influences the morphogenesis of children
The chlorophyll molecules are located in the thylakoid membrane
