Answer:

The correct answer to the question: The cell junction that allows adjacent cells to instantly exchange small moleculess and loss is:____, would be: B: A gap junction.

Explanation:

Gap junctions are precisely the one way in which two, or more cells, are able to exchange ions, molecules, electricity, and other elements, from one cytoplasm to the other. These junctions are created by channels that form from the separation between two different cells, usually between 2 to 4 nm. However, in order for cells of a tissue to be able to work together, and act together, they need some way in which they can exchange different elements. This is the job of the gap junction. A protein known as connexins, bridges the gap between the two cells forming a bridge, that connects the two cytoplasms and allows communication and interaction between the two cells. This includes allowing the passage of water-soluble molecules and ions to pass through them.

Glands may be classified in a variety of ways. Perhaps the most basic is classifying glands as either “exocrine” (secretion into a lumen or onto a surface) or “endocrine” (secretion into the circulation via capillaries).

In this given situation, we should stand behind him and administer abdominal thrusts.

<h3>Which part of the body should abdominal thrusts be administered?</h3>

Place the fist's thumb side against the person's stomach, just above the belly button and below the ribs. The muscle of the diaphragm can be felt. With the other hand over the fist, make a quick, powerful upward thrust into this muscle. Keep performing abdominal thrusts until the thing exits.

In order to remove things from the throat, the Heimlich maneuver employs abdominal thrusts. The diaphragm is a muscle that lies beneath the lungs. To assist the lungs in exhaling air, this muscle contracts. The Heimlich maneuver works by creating an artificial cough.

In a case-control study of obesity and adult-onset asthma, controls are matched to cases on the basis of race and gender.

Bess [88]

Answer: d. Confounding

Explanation:

In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).

For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
