Answer:
Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.
Explanation:
Active Transport works against the concentration gradient and therefore needs energy to make it happen
Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
It is 61 percent........so estimating it as 60 %
CHEERS MATE!!
The expression of genes in an organism can be influenced by the environment, adding the external world in which the organism is or where it develops, as well as the organism's internal world, which includes such factors as its hormones and metabolism.
