Answer:
Given that an amoeba is a protist (single-celled eukaryote), you should be looking at the nucleus.
Cooler and even the place in which it is is going to be more humid.
Answer:
If the producer population decreased, the size of the hervibores population will diminish.
Explanation:
Producer population refers to autotrophic organisms (plants for example). These organisms are the nutrition source for primary consumers (like hervibores). So if the nutrition source decreased, the population size of hervibores will decreased too.
Answer:
Pigmentation, (skin color), in humans has evolved under selection pressure from the duration and intensity of sunlight. Ancestral populations near the equator were selected for dark skin, while those living in higher northern latitudes were selected for lighter skin.
Mass number = total protons + neutrons, and proton number = total protons (and therefore electrons, if not an ion.) Therefore: Neutrons = 12 - 5 = 7 Protons = 5 Electrons = 5
