Answer:

The rate of mutation is faster than that of nuclear DNA.

Explanation:

Molecular clock is a term used to describe the genetic technique that allows the study of evolution at the molecular level, relating the time of divergence between species compared to the molecular differences in DNA sequences or in the composition of proteins.

In this case, the DNA of the mitochondrial and that of the ribosome is more advantageous to be used as a molecular clock. This is because the rate of mutation of these DNAs is much higher than the rate of nuclear DNA. This allows the researcher to identify many polymorphic regions that were generated in an evolutionary process of millions of years. As the mutation rate is constant, the large number of polymorphisms in these DNAs make them the best option as biological clocks

Iteru [2.4K]

Answer:

Basic Research

Explanation:

The initial discovery and analysis of the Lake Vida bacteria allowed them to be classified thereby leading to an understanding of their basic metabolic processes.

Although ,the introductory passage suggested several ways that this could lead to applied research by allowing the development of new products.

Conclusively, the research is a basic in nature because it gave a better understanding of the natural world.

To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible location

kramer

Answer:

The correct representation is attached with the explanation.

Explanation:

In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.

Interferons

Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.

<h3>What are Interferons ?</h3>

Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.

They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces

So that T cells surveying the area can identify and eliminate the viral infection.
