The vagina is at risk for infection because of its location and because it opens to the outside of the body. What is a protectiv
denpristay [2]

Answer:

The correct answer is- Normal vaginal pH is acidic (4 to 5), which protects from infection.

Explanation:

The vaginal part in woman have high tendency to get infection because of moist internal condition and its location but vagina also have a protective mechanism which protect it from the infection.

A woman's vagina contains many species of Lactobacillus genus which secrete lactic acid and hydrogen peroxide that maintains the low pH level in the vagina. So due to this reason, the normal pH of the vagina remains between 4-5 which does not allow pathogenic bacteria to flourish and cause infection.

God PLEASE help. What does surface area-to-volume ratio, diffusion rate, and time for substances have anything to do with reachi
sasho [114]

Answer:

Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.

Amoeba and some bacterias are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.

Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.

Explanation:

As the ratio gets smaller, it takes longer for items to diffuse.

Explanation:

When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.

When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.

this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

Transport proteins in the cell membrane play an important role in cell transport by
Kaylis [27]

Answer:    Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
