I believe that B and D are the only answers that I am sure of. C is incorrect and A seems incorrect as well. E may be a correct answer, but you will need to check the chemical equation. Hope this helps!
Gregor Mendal is known as the father of genetics. Mendal while a monk, used math to discover the basics of heredity by crossing pea plants with different characteristics for the f1 generation but when he crossed the f1 generation with a different pea plant he realized the traits that were in the original crossing to get f1 generation didn't show up until the f2 generation.
Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>

Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).
