Mars2501 [29]

Answer:

A) Bacteria cannot carry out RNA splicing to remove introns and so produced a much larger protein.

Explanation:

Human is a eukaryote and has both introns and exons in its genes. Transcription of human genes forms a primary transcript that undergoes post-transcriptional modification.

One of the important even during the post-transcriptional modification is the removal of introns and joining the exons together to make a mature mRNA which in turn serves as the template for protein synthesis.

<em>E. coli</em> is a prokaryote and does not have the enzymatic machinery required for the splicing of introns.

Cloning of a complete human gene into the <em>E. coli</em> cells would not form the respective human protein since the bacterial cells would not be able to splice the introns from the primary transcript.

How does capillary action help sustain life on earth? Uptake of food and water by plants Change in climates Water strider walkin
frez [133]
Capillary action is a combination of the adhesive and cohesive properties of water in which the water is able to move up a small tube against the pull of gravity. Therefore, the uptake of food and water is due to capillary action.

Change in climate has nothing to do with adhesion and cohesion in water. Some insects can walk on water due to surface tension, which is due to cohesion. However, there is no movement upward through a tube with surface tension, and so it is not an example of capillary action.

Hope this helps! :)

Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate
OleMash [197]

Answer: 0.69 m/ mile.

Explanation:

The altitude gradient between two cities X and Y = \dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%

Given: Two cities are separated by 200 miles.

City X has an altitude of 122 meters.

City Y has an altitude of 260 meters.

The altitude gradient between two cities X and Y =

\dfrac{260-122}{200}=0.69\text{m/ mile}

Hence, the altitude gradient between the two cites = 0.69 m/ mile.
