Answer:
<h2>Metagenomics is sequencing DNA from a group of species from the same ecosystem.
Letter A</h2>
Explanation:
<em>Advances in bioinformatics, refinements of DNA application, and the proliferation of computational power have greatly aided the analysis of DNA sequences recovered from environmental samples, allowing the adaptation of shotgun sequencing to metagenomic samples, known also as whole metagenome shotgun or WMGS sequencing.</em>
<em>Shotgun metagenomics provides information both about which organisms are present and what metabolic processes are possible in the community. Because the collection of DNA from an environment is largely uncontrolled, the most abundant organisms in an environmental sample are most highly represented in the resulting sequence data.</em>
Answer:
a
Explanation:
since runoff can be caused by little rainfall but in abundance of vegetation then it may decrease since they stop or slow down it's flow but runoff can not be affected by rocks since the velocity may even wear it
Answer:

Explanation:
If flies that are heterozygous for all three traits are crossed; e.g HtHtHt crosses with HtHtHt. The proportion of the offspring that would be expected to be heterozygous for all three traits will be: 1/8 because 50% (0.5) of their offspring will be heterozygous for just one trait. Therefore for three traits; we have (0.5)³= 0.125
0.125 is equivalent to 
From the table, the area of the asterisk region illustrate the traits that are heterozygous in the offspring.

"Directional selection" will most likely occur.
<u>Answer:</u> Option B
<u>Explanation:</u>
Directional selection or positive selection is an organic selection mechanism in population genetics, this scrutiny is an intense phenotype is preferred over certain phenotypes, allowing the intensity of the allele to migrate over moment towards that phenotype.
For an instance directional selection are fossil statistics showing that the scale of black bears in Europe diminished throughout ice ages interglacial phases however grew at each glacial period. A further example is the scale of the beak in a finch group.
The process that allows thermostats and thermometers to work is thermal expansion.
