Answer:

Option (B)

Explanation:

The Southwestern part of the U.S. is characterized by the presence of large mountains, canyons, plateaus, and some plain areas. These features are basically controlled by the continuous volcanic activity that is caused due to the sharing of a convergent boundary and transform boundary between the Pacific Plate and the North American Plate.

The eruption of volcano often releases a significant amount of harmful gases and other particles such as ashes, lava. Pyroclastic materials also erupt. These materials erupted for a long time in the geological past, which were solidified and formed a huge mass of rocks. Due to this continuous eruption and deposition of materials from the past, it gradually leads to an increase in the elevation of the nearby area. This is how volcanic activities configures the land areas.

Thus, the correct answer is option (B).

Which of these requires a host cell to copy its genetic material and protein coat?
svet-max [94.6K]

The virus' DNA becomes a part of the host cell's DNA, and every time the host cell copies and divides, it also copies viral DNA. The viral DNA may remain inactive (a provirus) for a long time, but it can become active when it frees itself from the host's chromosome, which triggers the lytic cycle.

I forget which one is the virus' DNA

Molodets [167]

Answer:

The all possible gametic haplotypes that can be made are described below.

Explanation:

According to the question, F1 progeny was produced by crossing a homozygous dominant parent with a homozygous recessive parent. As per the question, cross is to be made with a heterozygous parent, which will have solid unpatterned allele and blue colour with a homozygous recessive i.e lined, aqua lizard.

The possible haploid gametes for the heterozygous parent would be BL, bl, Bl, bL and for homozygous parent would be all bl.
