Miller used ammonia (nh3) as a reactant in his experiment. the atmosphere is 78% nitrogen; however, why would using a nitrogen source be important in this experiment

i believe the answer is a or 1

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
