Answer:

The correct answer is - option e. uses ATP as a substrate.

Explanation:

Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.

ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.

In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.

olga nikolaevna [1]

the formula to find force is F=ma

F- Force (in newtons)

m- mass (in kg)

a- acceleration (in m/s)

in this case you need to find acceleration, so isolate a by making the formula a=f/m. plug in your numbers then you're done

a=30/70

a=0.429 (rounded)

Briefly describe the cottagers living next to the creatures refuge
Likurg_2 [28]
The creature spent the entire winter watching and noticing the cottagers nest to him. The creature was taken by the beauty and nobility of their faces.
The cottagers were an old man, a young man and a young women. Despite not understanding their language or their music, the creature admired them.
The creature was determined to learn their language. It was able to acquire the basics by linking the spoken words with the actions that the cottagers did.
Watching them the entire winter, the creature passionately loved each one of the cottagers.
It could notice that the family was not happy, even though it could not figure out the reason. For the creature, the family had all the reasons to be happy. They possessed a roof, food and companionship.
Eventually, the creature understood that the reason behind their sadness was their poverty which was partially caused by the creature (which used to steal their food).
The creature was torn by his guilty conscience and stopped stealing their food. It even spend the night in gathering wood and leaving the wood at the cottager's door in order to help decrease their hardship.
