Answer:
The best description of the events occurring during Ana-phase I of meiosis:
c. Homologous chromosomes randomly separate and migrate to opposite poles.
Explanation:
Meiosis:
It is such type of cell division that occur in animals, plants resulting in four daughter cells and each of daughter cell have the half number of chromosomes from the parent cell.
- Anaphase is one of important phases of meiosis. The option a is incorrect as chromosomes go randomly to opposite poles.
- The option b is incorrect as all of chromosomes inherited from mother and father goes randomly to opposite poles.
- The option c is correct as it is the true description of anaphase I of meiosis.
- The option d is incorrect as the sister chromatids don't separate rather they remain joined.
A fully formed infectious virus particle that is able to establish an infection in a host cell is often called VIRION. It is a fundamental full component of a virus.
<h3>What is a virion?</h3>
A virion can be defined as an entire virus composed of a surface (protein shell) which is called capsid, and the inside nucleic acid.
The core nucleic acid of a virion can be either DNA or RNA (both single and double-strand).
A virion may infect a particular host cell to produce disease.

Answer:
Blood vessel, a vessel in the human or animal body in which blood circulates. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart. Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.

Answer:
Just one round without DNA repair
Explanation:
When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error
