Explanation:

Descriptive investigations attempt to build assumptions from either the predictions of the phenomena, even as experimentally investigated were mostly designed to allow the research scientist to make comparisons under various situations with both the control behavior.
There are indeed enough that-called comparison investigations, that also gather information analyze varying environments but don't even include the regulate location.

So that the above would be the appropriate answer.

Answer:

Blood sugar regulation in a diabetic patient is done by

Injecting prescribed quantity of hormone insulin after definite time intervals.
Consuming prescribed amount of sugars.
Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.

Explanation:

The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
In a diabetic patient, usually the beta cells of the pancreas are affected but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.

brilliants [131]

Answer:

Organism tend to adapt and evolve through natural selection.

Explanation:

Natural Selection can be described as a phenomenon by which those organisms are favored and selected by nature which are better adapted to live in an environment. These organism are able to reproduce and pass on their favorable traits to their offspring. Through natural selection, evolution occurs with the passage of time as those traits which are more suited to the ecosystem start existing in organisms.

A drawback to the use of the antacid drugs sodium bicarbonate, alka-seltzer, and baking soda is their high sodium content.

Explanation;
Antacid drugs are weak bases that exert a therapeutic effect by neutralizing hydrochloric acid, thus relieving indigestion, heartburn and hyperacidity.
