Can someone tell me if 1-4 is right?

It looks right, but i think the worksheet should have included another word for the study of heredity because heterozygous isn't that, but nothing else fits

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
