I believe it’s B. They have enteric fermentation and release methane. enteric fermentation takes place in the rumen. That’s when bacteria break down complex carbohydrates into simple sugars. The end products of enteric fermentation by bacteria include volatile fatty acids (VFAs) as well as gases, such as carbon dioxide and methane. What cows eat has a big effect on how much methane they produce.

To ensure that a human gene is translated properly in a bacterial cell, you should clone the _____________ for the gene instead

bekas [8.4K]

Answer:

complementary DNA (cDNA)

Explanation:

The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.

Tanya [424]

The type of solution formed is hypertonic.

<h3>What are hypertonic solutions?</h3>

Hypertonic solutions are solutions with higher dissolved solutes as compared to the sap of the cells suspended in them.

Epsom salt is made up largely of magnesium sulfate. Thus, a solution formed by dissolving Epsom salt is water will have more magnesium in it than the cells of the part of the body soaked in it.

Hence, such a solution is hypertonic.

Novosadov [1.4K]

Answer:

Parents: Yellow (Aarr) and Grey (AaRr)

Explanation:

Given:

allele A = yellow

allele R = black,

Heteroozygous = gray

Genotypes of the parents:

yellow (Aarr) - female

gray (AaRr) - gray

cross between these

Parents: Yellow (Aarr) and Grey (AaRr)

Gametes: (Ar, ar) and (AR, Ar, aR, ar)

F1 (Punnet square)

----|----- AR ------|------- Ar ------|------ aR -----|----- ar

Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)

ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)

Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
