What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Y_Kistochka [10]

Answer:

The options to this question are:

A) allele

B) codon

C) nucleotide

D) chromosome

The answer is A) allele

Explanation:

RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.

However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

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>

How would being able to bring water into the gills when the mouth is closed benefit a bottom-dwelling shark or ray?
trapecia [35]

Answer:

The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.

Explanation:

I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.
