4. Which of the following statements about reinforcement is true?a. Reinforcement increases the number of intermediate phenotypes.
b. Reinforcement is a type of natural selection.
c. Reinforcement decreases the morphological difference between two incipient species.
d. Reinforcement is also called dispersive selection

Answers

Answer 1
Answer:

The  statements about reinforcement is true is that Reinforcement decreases the morphological difference between two incipient species.

Option C is correct.

How do we explain?

Reinforcement is  described as a type of natural selection that occurs when two populations that are becoming reproductively isolated from each other start to develop preferences for mates from their own population.

This can lead to a decrease in the morphological difference between the two populations, as they become more adapted to each other's mating preferences.

In conclusion, reinforcement is a type of natural selection, not the other way around. Option d is incorrect because reinforcement is also called assortative mating, not dispersive selection.

Therefore option B is correct

How is the virus reproduced during the lysogenic cycle?
a. through reproduction of the host cell
b. by using viral enzymes to reproduce viral DNA
c. by using the cell's enzymes to reproduce viral DNA
d. by breaking the cell open and releasing new viruses

Answers

Ans. (b). has a genome made of RNA.

Retroviruses are viruses with RNA molecules as their genome. They insert a copy of their RNA genome into the host cell DNA and change the cell genome. These viruses are generally known as single-stranded positive-sense (+ strand) RNA viruses.

Examples: Human immunodeficiency virus and hepatitis B virus.

Thus, the correct answer is option (b).

Ans. (a). through reproduction of the host cell.

Lysogenic life cycle is a virus reproductive cycle that involves integration of viral nucleic acid into host's genome or formation of a replicon in host's cytoplasm.

The host cells (bacterial cells) remain alive and reproduce normally, so thus, viruses reproduce through the reproduction of host (bacterial cells).

Thus, the correct answer is option (a).

A retrovirus virus has a genome made of RNA. A virus during the lysogenic cyle is the reproduction through the host cell.
