Answer: Very unlikely

Explanation:

Generally, point mutation can be easily reversed by another point mutation, so

before any changes occur in the amino acid sequence, it would have been corrected.

However, when point mutation occurs within the protein coding region of a gene it may results in the change of a single nucleotide to cause the substitution of a different amino acid (which renders the protein non-functional) as in the case of sickle-cell disease.

And this kind of point mutation is specifically called Missense mutation.

Above all, because point mutation is easily reversible, it is very unlikely to change the amino acid sequence of a protein

What male reproductive structure releases sperm into the vas deferens?
lisov135 [29]

The answer is epididymis.

<span>Testicles contain seminiferous tubules, in which sperm is produced, and an epididymis, in which sperm matures. Mature sperm passes through the epididymis to the vas deferens. There, it combines with a liquid secretion from the seminal vesicles and continues through the prostate gland to the urethra. Sperm containing fluid is called semen and it is ejected through the urethra.</span>

What is the essence of the catalase test?
garik1379 [7]

Explanation:

Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.

This treaty regulates international relations with the Antarctica region. Freedom to different scientists for research in this area was given through this treaty.
