Answer:
A symbiotic relationship is the one where the interaction of different types of species takes place. The two species remain in close proximity. The relationship can be either harmful, or beneficial for both of the species. Commensalism, parasitism and mutualism are the examples of the symbiotic relationship. In commensalism, the two species lives in close association and one species receives the benefit and the other receives no harm and benefit. In parasitism, the two species lives in close association, in this one species receives the benefit and cause harm to the other species. In mutualism, the two species lives in close association, in this both species receives the benefit of association.

Answer:
Soil survey, or soil mapping, is the process of classifying soil types and other soil properties in a given area and geo-encoding such information. ... An architect or engineer might use the engineering properties of a soil to determine whether or not it was suitable for a certain type of construction.
Answer:During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. ... During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase.
Explanation:
The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.
