How does the cell membrane help maintain the homeostasis of water content?

1 answer:

5 0

The water wants to flow from the higher concentration, which is outside of the cell, to the lower concentration, which is inside of the cell. The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis.

Form a hypothesis about how the loss of estuaries can increase erosion along shorelines

lakkis [162]

Answer:

The hypothesis can be made as follows:

' If there are less or no estuaries in a river, then there will be more erosion at the shorelines.'

A hypothesis is a tentative statement which can either be supported through experiments or proven to be wrong.

In the following scenario, we can conduct experiments by taking into observation those rivers which have estuaries and those which do not have estuaries. We can then compare the erosion of the shorelines of the rivers to validate our hypothesis.

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Explanation:

Step 1: Define

Point (0, -7)

Point (7, 0)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{0+7}{7-0}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{7}{7}$
[Fraction] Divide: $\displaystyle m=1$

A. If the optimum temperature for a cell's functions is exceeded, chemical reactions slow down as enzymes and other proteins begin to denature (change shape due to increased vibration of the atoms in the molecules that make up the proteins).

What happens to an animal cell in a hypertonic solution?

jarptica [38.1K]

The answer is that cell will shrink.

If you put an animal cell in a hypertonic solution means that concentration of the solutes is greater outside the cell, in the solution, than in the cell. Consequently, the water concentration of the cell's cytoplasm is higher than that of the hypertonic solution. Since the aim is to balance water concentration on the inside and outside of the cell, the water will exit the cell. The cell will lose water and, consequently, will shrink in size.
