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.

Marta_Voda [28]

Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>

<u />

Explanation:

  • An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
  • The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ.
  • Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
  • Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples
