Answer:

A single nucleotide polymorphism (SNP) is the most common gene variation found among people. A SNP represents a change in a single DNA block, called a nuecleotide, being able, for example, to replace a nucleotide cytosine (C), with a nucleotide thymine (T), guanine (G) or adenine (A) in the genome. They represent the 90% of all the human gene variations.

Virus? Living or not? If we use the image as an indicator, we might say living because
kondor19780726 [428]
A virus is a tiny organism and may lead to mild-severe illnesses in animals or plants or humans.

Biologically we can term virus as a bit of RNA or DNA in a protein coat. It cannot replicate without another organism.

If we use an image of indicator, we may say yes virus is living. This is because the virus particle is non-cellular but has an NDA core.This core is enclosed in a protein coat and it has spike-like projections in all over its surface.

What is unique about a hominid pelvis when compared to other primates
ki77a [65]

Answer:

The hominid pelvis displays many unique features (when compared to

that of quadrupedal primates) that support bipedalism. The major

adaptations are seen in the sacrum and the ilia, as well as in the

overall configuration and orientation of the pelvic bones.

Explanation:

These changes in the sacrum were for the adaption of standing on two legs,

The uniqueness is also that ilia are rotated and curved medially, bringing the lateral edge of  the blade forward and projecting the top of the ilia outward laterally.
