all kinds of cells.

Student 3: The cell membrane produces proteins and is found only in animal cells. Student 4: The cell membrane produces carbohydrates and is found only in

prokaryotic cells.

A. Student 1

B. Student 2

C. Student 3

D. Student 4

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

tissue

explanation:

it is actually formed by geoup of cells which is tissue

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
