In an experiment, a scientist studied the effect of increased levels of calcium had on a sugar levels in the blood. The scientis
ololo11 [35]

Answer:

If the calcium levels in blood increases, then there is increase in blood glucose level.

Explanation:

Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several  researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.

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.
