Answer:lipid molecules

Explanation:

lipid molecules prevent membrane from dissolving and they are also known as phospholipids.

A lipid molecule could be imagined as rectangle. With one end i.e the bottom of the lipid molecule that is hydrophilic which means they are water-loving.

The other end of the head of the lipid molecule which is hydrophobic, which is the non-polar and water-fearing end of the molecule.

Within protective layer surrounding the outside cell(Cell membrane) there are large amounts of lipid molecules. Phospholipids are the most abundant that prevent membrane from dissolving.

Water is a polar solvent and prefers dissolving polar molecules such as salt but Lipids is a non polar molecule and can't be dissolved by water the presence in abundance prevents dissolution.

Mrrafil [7]

Answer:

Remain with the client and be silent

Explanation:

Bowel obstruction can be explained or described as a situation whereby the intestines, i.e, both small and large intestines are blocked, and thereby, preventing the normal movement of food, liquid or stool in the intestines.

The blockage could result or occur due to tumor, foreign substance or digestive problem.

The Miller-Abbott tube is the tube that was invented or developed to treat the obstruction that is present in both the small and the large intestines. It is used by passing it through the stomach into the intestine.

In this case, the bowel obstruction is caused by recurrent malignancy, that is recurrent of formation of tumor.

The best thing the nurse should do, is to remain silent and with the client, until the client is ready for explanation on the process, and that he/she is in position and capable of inserting the tube.

Cerrena [4.2K]

Answer:

c. when you get to college you change the way you dress so that you "fit in" better--that is, so that people will like you more.

Explanation:

Informational social influence leads to internalization (private acceptance) of the majority opinion/behaviour i-e you actually change your attitude / belief. It is basically a difficult task , unsure of the answer, usually ambiguous , actually use others's response to form an opinion and actually believe what others say and internalize in. It is usually found in the crisis situation, when you don't know what to do and following th advice of expert. Examples include listening to fireman.

Hence in the given options, only c. when you get to college you change the way you dress so that you "fit in" better--that is, so that people will like you more. seems not to be example of Informaltiona social influence.
