Answer:
In cotransport, a single ATP-powered pump that transports a specific solute drives the active transport of several other solutes. Normally, sodium in waste is reabsorbed in the colon, maintaining constant levels in the body, but diarrhea expels waste so rapidly that re-absorption is not possible, and sodium levels fall precipitously. To treat this life threatening condition, patients are given a solution to drink containing high concentrations of salt and glucose. The solutes are taken up by sodium-glucose cotransporters on the surface of intestinal cells and passed through the cells into the blood. This simple treatment has lowered infant mortality worldwide.
Answer:
Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.

The correct answer is: smooth endoplasmic reticulum (smooth ER).
Smooth endoplasmic reticulum is a membrane organelle of the eukaryotic
cells which consists of tubular membrane vesicles. One of its main function is the synthesis of lipids and their storage. For example, cholesterol and phospholipids are stored in the smooth ER and then used for the synthesis of plasma membrane.
There is another type of ER- rough ER. The difference between these two ER on its outer surface have attached ribosomes- protein-synthesizing particles .
