seraphim [82]3 years ago
3 0

Answer:

The correct answer will be option-A.

Explanation:

The neuromuscular junction is the junction at which the motor neurons brings the signals to form the CNS to cause the response.

The motor neurons carry the signals in the form of action potential and have to pass on this information to the muscles. The muscle cells of muscle fibers receive these signals form motor neuron at this junction by modifying the ends of its structure by folding its end. This folded structure is known as the "motor end plate" which receives the signals and transfers the same to the sarcomere and causes the muscle contraction.

Thus, option-A is the correct answer.

Lemur [1.5K]

Answer: incomplete dominance

Explanation:

Incomplete dominance is also referred to as partial dominance or semi dominance. It occurs when the two forms of gene in a trait combine in such a way that one does not have a dominance over the other one. Therefore, there's a blend of both genes in the physical appearance of such organism.

Therefore, a low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice is an example of incomplete dominance.

A researcher has identified a mutant strain of yeast whose histones are unable to be acetylated. Which of
d1i1m1o1n [39]

Answer:

The correct answer is c the mutant will show decreased levels of gene expression.

Explanation:

Histone acetyl transferase is an enzyme that helps in the transfer of acetyl group to the epsilon -NH2 group of lysine reside of histone proteins that surrounds the DNA molecule of chromosome.

  This results to make the target DNA more assecible for transcription mediated by RNA polymerase resulting the gene expression.

 On the other hand the mutant in which histones are not acetylated,transcription rate decreases as the non acetylated DNA is less assecible to RNA polymerase.
