Intermediate magma is also known as andesitic magmas and these are created when an oceanic plate subducts beneath a continental plate. The magma is generated in the wedge of mantle rock beneath the crust. The Cascade Mountain Range is formed due to the subduction of the Juan de Fuca Plate beneath the North American Plate.

kicyunya [14]

Hello. This question is incomplete. The full question is:

"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment? "

Answer:

Approximately 29 cycles of PCR would be required.

Explanation:

As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.

PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.

In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:

32 ^ x = 10 ^ 9

x = 28.3 = approximately 29 cycles.

djyliett [7]

The correct answer is: a. A field dominated by annual herbaceous plants.

This is because annual herbaceous plants (plants that have no persistent woody stem) die completely at the end of the growing season or after they have flowered and fruited. They will then grow again from seed.

Margaret [11]

Answer:

The gene frequency for the albino allele is 16%.

Explanation:

Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:

16/100 = X

0.16 = X

1 = 100

0.16 = X

0.16 x 100 = X

16 = X

Therefore, the gene frequency for the albino allele is 16%.
