How does the structure of the cell membrane help the cell regulate water?

1 answer:

6 0

The major purpose of the cell membrane is to regulate the types of substances that enter the cells and leave the cell, thus, it is a semi permeable structure.
The structure of the cell membrane help the cell in regulating the amount of the water inside the cell because, when the optimum amount of water is inside the cell, the membrane will not allow the pasage of water molecules into the cell again.
And in a situation, where the concentration of substance inside the cell is above the normal concentration, the cell membrane will allow the required amount of water to flow into the cell in order to reduce the concentration.
Also, the phospholipid bilayers that are found in the cell membrane help to regulate water homeostasis of the cell by using its hydrophobic tail to repel water molecules and thus keep them out or inside of the cells.

Air resistance is negligible.

Dahasolnce [82]

Answer:

The correct answer will be- false (only in vaccum condition is negligibe)

Explanation:

Air resistance is the force applied by the air on the moving object in the atmosphere which opposes the motion of the object. Since it opposes the motion of the object therefore, it slows down the object.

In atmospheric conditions, the air resists the acceleration and changes the speed of the object but in vacuum conditions, since it has no air, the air resistance is considered negligible.

Thus, false (only in vacuum condition is negligible) is the correct answer.

1. metal moderate ability to conduct heat and electricity; solid at room temperature; reacts with other elements 2. nonmetal gas

vladimir1956 [14]

The question is not given. You just placed some statements. Apparently, here you have some definitions to pair with the type of elements. So, I will separate the statements as per my best understanding. If the question requires anything else tell me to give you more details.

<span>1. Metalloid

Metalloid is an element that has properties in between metals and non metals, this is metalloids have some properties of both.

Then you can pair it with ---> moderate ability to conduct heat and electricity

2. noble gas

The elements that are knwon by not reacting with other elements are noble gases.

Then, pair this with ---> will not react with other elements.

3. metal:

Metals are malleable, polishes to a luster and are good conductors of heat and electricity.

Then pair metal with ---> malleable, polishes to a luster; conducts heat and electricity well

4) non metal gaseous: non metal are poor conductors

So, pair this with ---> does not conduct heat or electricity well

Given that the question is no
