Which energy transformation occurs during active transport in a cell? O A. light energy chemical energy
B. kinetic energy
potential energy
C. chemical energy
mechanical energy
o
D. mechanical energy → electrical energy

During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

plz mark me as brilliant

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

the correct answer is 2 and 4
