Unlike a lytic infection, a lysogenic infection

1 answer:

5 0

The best answer is A.

In a lysogenic cycle, the viral DNA or RNA enters the cell and integrates into the host DNA as a new set of genes called prophage. The prophage is passive and non virulent and does not destroy the cell. However if the prophage undergoes any stress or mutation or is exposed to UV radiation, it may adopt the lytic cycle and become infective.

In a lysogenic infection, there are no viral symptoms and it occurs after the viral infection is over. But the viral DNA or RNA remains in the cell and may remain there permanently .

Answer:

I think the answer is A

Explanation:

Since the question states that they want to determine the population of the desert mice. You get the direct answer from just using context clues. Since population means one species in a certain area, it means that this method will work if the mice stay in the same area.

Explain what constitutes the internal environment

nevsk [136]

Answer:

Water based fluid

Explanation:

The internal environment consists of water based fluid in which the cells of the body present. A fluid called interstitial fluid or tissue fluid bathes the cells and provides essential nutrients to the cell. The human skin has fatty layers that helps to maintain internal heat which is produced by the body when the outside environment is cold. When there is cold in the environment, people lives in warm shelters and wear warm clothes in order reduce the impact of cold environment.

Which part of the nervous system is made up of cells that send and receive tiny electrical charges?

Hoochie [10]

Answer:

Neurons

Explanation:

Neurons are specialized cells, found in the nervous system, which transmit information.

Neurons contain a dendrite, a soma, and an axon. Some axons are covered with a fatty substance known as the myelin sheath, which surrounds the axon, acting as an insulator and allowing faster transmission of the electrical signal.

What is the purpose of meiosis? How does the cell do the following: reduce the chromosome number in half and create genetically

s2008m [1.1K]

Answer:

2 cells meet and the number of chromosomes becomes equivalent to the somatic cell.

Explanation:

In meiosis crossing over occurs and the number of chromosomes divided or remain half as compared to a somatic cell which is called Haploid (n). When two haploid cell meets than diploid (2n) cell formed which further transforms into a zygote. So, the purpose of meiosis is the cross over which creates genetic variation among individuals and reduced the number of chromosomes into the half. Because if the number of chromosomes remains the same as (2n) and (2n) meets and becomes 4n. Which is the wrong pattern so nature keeps this balance in a unique manner that (n) and (n) meets and form (2n).
