Humans and mice differ because
maksim [4K]

The answer is d.their cells have some differences in the sequence of nucleotides in their nucleic acids

Human and mice is both mammals and have similar structure and metabolism. There should be no big differences in biological or organic molecule. The big differences should be the sequence of the nucleic acids in their DNA. Mice could produce similar protein in human, but the DNA is different.

Gravity is a force which causes objects to fall or be still on the earth's surface. This invisible force has been longed explored mainly by many scientist however, Isaac Newton was first to conceptualize this into a proper principle. 

GravityLight is a device that was recently developed by engineers that is designed to produce light through the force of gravity.

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.
