How do cells affect the size of an organism? As animals grow in size, they produce more cells.
As cells expand or shrink, the size of an organism can change.
More cells can produce more chemical energy, allowing animals to get larger.
Larger cells produce larger-sized organisms.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

it's false. hope i .
