Biology
1 answer:
Dominik [7]3 years ago
6 0

Answer:

The correct answer will be option-B.

Explanation:

Viral polymerases are the enzymes which play an important role in the viral genome transcription and replication.

Retrovirus is the single-stranded RNA viruses which replicate through a DNA intermediate and therefore requires the <em>RNA-dependent DNA polymerase or reverse transcriptase</em>. Reverse transcriptase encodes DNA from the strand of RNA which can be replicated and helps in the reproduction of the virus.

Thus, option- B is the correct answer.

Ipatiy [6.2K]

Answer:

I am 90% sure that it is Number 3. Sorry if it wrong...

Explanation:

Most volcanoes form at the boundaries of Earth's tectonic plates. ... The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Divergent Plate Boundaries. At a divergent boundary, tectonic plates move apart from one another.

An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

Hope this helped!!!!

A normal female X H X H marries a man who has hemophilia.
Citrus2011 [14]

Answer:

0%

Explanation:

Normal female genotype = X^HX^H

Genotype of a man with hemophilia = X^hY

Crossing the two in marriage:

X^HX^H   x   X^hY

Progeny: X^HX^h, X^HY, X^HX^h, and X^HY

<em>The two sons from the cross have the genotype </em>X^HY<em> and are therefore free from hemophilia.</em>

Hence, the percentage of their sons that will have hemophilia is zero (0).
