frosja888 [35]

Answer:

the appropriate tone to use in this instance would be a stern but kind and understanding tone. you don't want to be too forecul in order to avoid the patient rebelling however, you must be stern since it is a matter of life and death; the best course of action is to be entirely honest about the serious effects his habits have on his health. Based on his past actions of following the regimens prescribed by other doctors, he seems to want to lose weight and do better. The best way is to entirely avoid the point of temptation and try to keep it out of sight and out of mind. being kind is important since people react better to kindness rather than control, showing how much you care could cause the patient to want to do better.

Nady [450]

This tube consists of multiple sections which each have their own specific functions to perform in the process of digestion. The sections of the Alimentary Canal in the order in which they process food are

the function of the lingual papillae are

The alimentary tract serves primarily to convert food into absorbable particles and to pass them on to the other organs of the body. These events are initiated by mechanical processes (fragmentation, mixing, transport) and the secretion of digestive juices containing enzymes, which act to split proteins, fats and carbohydrates by hydrolysis into constituents small enough to be absorbed (digestion). These end products of digestion, together with water, minerals and vitamins, then pass through the intestinal mucosa, from the lumen of the intestine into the blood and lymph (absorption).

Steroid hormones
kondor19780726 [428]

Answer:

A) bind to receptors in the nucleus of their target cells.

Explanation:

Steroid hormones are synthesized from cholesterol and are lipids, therefore they cannot be transported in the blood dissolved in the plasma. They are associated with transport proteins to travel in blood.

Because they are lipids, they can diffuse through cell membranes, and once inside the target cell they bind to receptors in the cytoplasm or the nucleus and alter gene expression.
