Answer:

option B: Polygenic inheritance

Explanation:

Polygenic inheritance in genetics and plant breeding can be defined as a type of inheritance whereby  one or a single trait or  characteristics(color)  is controlled by multiple genes (two or more genes). it is a continuous variation that depicts a normal distribution curve

the phenotype of a plant or an animal increases if when there is an increase in the number of genes controlling a particular trait or characteristics. polygenic inheritance are non-Mendelian form of inheritance in  nature and a  single trait expressed is as a result of the interaction of many or multiple genes that are quantitative genes in nature. examples are weight, skin color, height, e.t.c

AZT is a reverse transcriptase inhibitor. How does this drug prevent the replication of a retrovirus
Artemon [7]

Answer:

AZT is a thymidine analog

Explanation:

Azidothymidine (AZT) is an antiviral drug used for the treatment of the Human immunodeficiency virus infection (HIV/AIDS) by preventing the transmission of HIV from infected cells. AZT is capable of suppressing the activity of the enzyme reverse transcriptase of the retroviral HIV genome, which enables it to copy RNA into DNA. In infected cells, this double-stranded DNA is integrated into the host genome which is then instructed to produce identical HIV copies. AZT is a thymidine analog that is incorporated into DNA and thus interferes with DNA synthesis, thereby inhibiting cell proliferation.

kondor19780726 [428]

Explanation:

Explanation:

<em>Complete answer: </em>

<em>a. foot tapping rhythm </em>

<em>b. long-term memory </em>

<em>c. breath holding </em>

<em>d. circadian rhythm </em>

The cerebral cortex plays a major role in all of the following except d. circadian rhythm

The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.

The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.
