Answer:

The heart has four chambers: The right atrium receives blood from the veins and pumps it to the right ventricle. The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

The four chambers of the heart are Right Atrium, Left Atrium, Right Ventricle, Left Ventricle.

The right atri.um is located in the upper right corner of the heart superior to the right ventric.le (superior to the right ventricle and anteromedial to the left atrium)

The left atriu.m is located in the posterior aspect of the right at.rium, next to the superior vena cava (superior to the left ventric.le, posterolateral to the right at.rium, posterior to the aortic root, and anterior to the esophagus)

The right ven.tricle is located in the lower right portion of the heart below the right at.rium and opposite the left ventri.cle (extends from the right atri.um to the ape.x of the heart)

The left ven.tricle is located in the bottom left portion of the heart below the left atr.ium, separated by the mit.ral valve (in a posterior and lateral location relative to the right ven.tricle)

Sorry for the periods in between the words, it kept saying it contained innappropriate words even though it didn't

During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA pol

svetlana [45]

Answer:

mRNA interacts with ribosomes in the cytoplasm.

Explanation:

<em>The correct option would be that mRNA interacts with ribosomes in the cytoplasm.</em>

Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.

<u>During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon</u>.

Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.

Matings between individuals from the two populations of Rhagoletis produce hybrid flies that appear to be healthy and have norma

Mama L [17]

<h2>The correct answer is : C.</h2>

Explanation:

According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.

Name 2 differences between plant and animal cells.

Zanzabum

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.
