Answer:

C. They all use a cut and paste mechanism.

Explanation:

DNA transposons can go through a replicative or nonreplicative transposition.

The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.

The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.

Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.

Explain the effect that hypoglycemia has at the cellular level, specifically on cellular respiration.
Fofino [41]
When a person is diagnosed of hypoglycemia, it indicates that a person has a low (below normal) blood glucose or low blood sugar in the blood. When a person is hypoglycemic, cellular respiration cannot take place. The oxygen that normally combines with glucose, which are supposedly converted to energy (ATP, adenosine triphosphate) during cellular respiration, accumulates in the bloodstream resulting to an increase pH and inactive enzymes -- essentials of cellular respiration.

Hello. You forgot to enter the answer options. The answer options are in the figure attached below:

Answer:

the option D is the right answer.

Explanation:

Option D shows a pathway where activation of the receptor would lead to an increase in gene expression. This is because in this option we can see that the transcription regulator is decreasing gene expression, but there is a receptor that is activated and that has the ability to inhibit the pathway, allowing the selected gene to be expressed efficiently. This is because the pathway shows two inhibitory steps, when this happens an activation is performed.

Which movement results after the contraction of the serratus anterior muscle?
Kobotan [32]
<span>The resulting movement is scapular protraction and rotation.The scapula is moved along the chest wall. The muscles involved in this process are the serratus anterior, which is the prime mover. Pectoralis minor and major, the latter acting through the humerus, may assist (act as synergists).</span>
