Answer:
Actually, the main pigmenting (coloring) agents in soils are organic matter, iron, and, to a lesser extent, manganese. When these agents are not covering the mineral grains, the natural color of the grains is visible. Colour is a simple method of classifying soil. Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure.he colour of the soil varies from one place to the other because soil is formed out of different types of rock . Since rocks are of different colours and textures , the colour of the soil varies from one place to another .
Explanation:

Answer:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. ... The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation.
Explanation:
Answer: The question is is incomplete, here are the options.
A. Separating the two groups decreases the chance that the two groups will diverge
B. Traits that form in one group from evolutionary forces quickly spread through both populations
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently
D. Gene flow is increased in the two subgroups that are formed
The correct Option is C.
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently.
Explanation:
Forces of natural selection and genetic drift affect the genes of the two subgroups differently because there are differences In the way they are natural selected and genetic drift.
Natural selection is the different phenotype or traits developed by different organisms who h make them to adapt, survive and reproduce than others in their environment. The two sub groups have different phenotype Expressed which cause them to develop different trait.
Genetic drift refers to change or variation in frequency of genes in animals overtime. Genetic drift occur at different rate in different population of organsim which lead to development of different trait in the subgroup.
