Answer: True.
Explanation:
Humus are decayed dead plants and animals in the soil. They are decayed organic matter(plants and animals). They are formed by the incorporation of plants and animals matter in the soil by the action of microorganisms. Humus provide nutrients for the soil, increase soil porosity and create good soil tilth. The good soil with help microganisms to perform their actions in the soil and improve soil structure.
Answer:
Number 3
Explanation:
Dominant: 20, Recessive: 20
An allele is the alternative of a gene. On his case, these beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r).
As states earlier there are 20 red beans (20 dominant alleles) and 20 white beans (20 recessive beans) and each beach represent an allele.
Anthropoid
Pretty sure that is right B/C they have a exoskeleton, they are land animals primarily (Oxygen Tubes), they have joints and have two body segments.
Enzymes.
because enzymes are a substance produced by a living organism that acts as a catalyst to bring about specific biochemical reaction.
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).
