Answer:

\boxed {\tt D. \ Microorganisms}

Explanation:

A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.

An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.

Let's examine our answer choices.

Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.

That leaves: <u>microorganisms.</u> Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms

prohojiy [21]
Carbon is one of the most common elements

Can form bonds and double bonds with up to 4 other atoms, including other carbon atoms

If you add more elements and you can create amino acids, and that is the base of all proteins.

If you need more help on this, watch some videos by Neil Degrasse Tyson. World-renown astrophysicist (and my idol) who does lots of talks about things just like this.<span />

A population of horses has individuals that are either gray or chestnut colored. The gray color allele, G, is dominant over the
Dahasolnce [82]

We solve the problem using the Hardy-Wineberg equation.

We have the frequency for gray trait as p =  = 0.8

∴ p² = 0.64

64 % of the horses are homozygous for the gray trait.

Solving for the frequency of white chestnut trait by using the fact that,

p + q = 1

∴ q = 1 - p = 1 - 0.8 = 0.2

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous gray trait,

∴ 2pq = 2 x 0.8 x 0.2 = 0.32

Therefore, in a population of 100 horses, 32% are heterozygous for gray trait.

Hence the total number of gray horses in a population of 100 will be,

32 (heterozygous gray horses) + 64 (homozygous gray horses) = 96 (gray horses)

Hence, 96% of the horses are gray in color.
