Three examples would be gamma rays (usually these rays are emitted from unstable isotopes and can be used in nuclear experiments and testing) ultraviolent rays that are emitted from the sun and can cause sunburn and even skin cancer because the rays mutate the DNA in the skin cells nucleus. And also X-Rays, microwaves, and radio waves, which is usually harmless because it isn’t enough radiation to mutate DNA in our cells
I hope this is what you wanted
I feel like the answer would be A because photosynthesis gives off energy and they don’t produce glucose
Mitosis is the process by which the nucleus of a cell divides to form two new nuclei?
