Answer:
Trenches are formed by subsection, a geophysical process in which two or more of Earth's tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
Explanation:
The rock pocket mouse, which has dark fur, lives on black lava rocks. While Apache pocket mouse, which has light fur, lives on the tan sand in the southwestern part of the United States.
<span>The difference between them is that an Ecosystem is a community of organisms and their environment. And a biosphere is all the living organisms.

Answer:
- acceptable for biochemical pathway to remain unknown
- identifies novel candidate genes for a disease
- allows for large sample sizes with a limited budget
- identifies DNA elements that flank a variant
Explanation: Genome wide association studies (GWAS) are a relatively new approach to analyzing genetic sequence and have quickly become a fundamental part of modern genetic studies. Their purpose is to determine alleles that correlate to different diseases and traits.
GWAS focuses on SNPs. The modern unit of genetic variation is the single nucleotide polymorphism or SNP. SNPs are single base-pair changes in the DNA sequence that occur with high frequency in the human genome, inother words, the single nucleotide sites that differ between individuals. By studying SNPs, researchers can analyze a few hundred thousand nucleotides rather than the 3 billion nucleotides that compose the human genome. The basic design of a GWAS is simple and begins by dividing participants into two groups:
* People with a disease/trait of interest
* People without a disease/trait (control group)
