The Sun is the source of energy for photosynthesis
Maybe a lake or somewhat like a geo
Here are two examples of how nutrients help to maintain homeostasis in our body:
1. The carbohydrates that we take gives us the energy that we need. It serves as our main source of energy, especially for the brain, to function properly. Having the right and sufficient amounts of carbohydrate intake maintains the normal blood glucose in the body.
2. The intake of sufficient vitamins is necessary for the synthesis of collagen that is important for the structure of the blood vessels, bones and ligaments. Specifically, vitamin D helps in maintaining the homeostasis of calcium in the body. This vitamin can be found in food sources or synthesized by the sun.

This can be solved either by using a Punnet Square or you can use the formula (n(n+1))/2, where n is the number of alleles. However, using either method will give you the number of possible genotypes regardless if it's homozygous or heterozygous. If we use the second formula, that will give you 10 possible genotypes. Since you only want to know the number of heterozygous genotypes, you should subtract the number of possible homozygous genotypes. In this case, there are four. That is (A1,A1), (A2,A2), (A3,A3), and (A4,A4). Knowing this, you'd be able to figure out that there are six heterozygous genotypes.
(A1,A2), (A2,A3), (A3,A4), (A1,A4), (A1,A3), (A2,A4)
