There Is a phase in mitosis called G0, which occurs before the other stages. jn this stage, cells grow in order to become big enough go divide, meaning cells take the time to grow in order to divide at the same sizs.
It is the second option
Gg symbolises green color(because G is dominant so it will be green) and GG symbolises yellow( as there is no dominant trait present)
Photosynthesis: Chloroplast, Cellular Respiration: starts in chloroplast, but mostly in the mitochondria. Hope I helped!
Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.
