Answer:D
Explanation: Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells
Osteoarthritis is the repeated use of a joint which gradually wears down
the articular cartilage.
<h3>What is a Cartilage?</h3>
These are soft connective tissues which are found between bones which
helps to ensure flexibility and reduce friction.
In most old people, these cartilages being to wear out thereby increasing
the friction between the bone joints. This leads to osteoarthritis which is
characterized by joint pain.

Answer:
Cellulose.
Explanation:
Cellulose is the polymers of glucose present in plants. Cellulose provides the structural and functional framework to the plant cell. Cellulose is also present in algae and fungi.
The cellulose consists of the glucose unit made of β glucose. These glucose units are linked together through the glycosidic bonds and a small molecule like water is released during the polymerization of glucose to form cellulose.
Thus, the answer is cellulose.
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.
