Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase

into an early phase and a late phase. Which of these has occurred by the end of prophase?

Answer:

Explanation:

At the ending of pro phase or late prophase, the mitotic spindle begins to capture and organize the chromosomes.

* The chromosomes have finished condensing and are now very compact.

* The nuclear envelope is broken down and the chromosomes are released.

* The mitotic spindle grows more, and some of the microtubules start to “capture” chromosomes.

Answer:

D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation

Explanation:

The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.

The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).

The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).

From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.

Thus, Option-D is correct.

Learning objective: 12.08.05 describe the initiation and propagation of depolarization and repolarization.
denis-greek [22]
Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.

Mashutka [201]

Answer:

                 

Explanation:

I am the thing that goes bump in the night. The shadow-like figure all are too afraid to identify in their room. The silent stalker of your waking nightmares and lucid dreams. Do not worry, I can- but will not- hurt you. Your family, however, doesn't have such luck. Do not warn them that I will be following their every move, or it will lead to a grizzly fate for you and your bloodline. I hope that my message has given you closure for the events to come.

In the meantime, you can pray for your family. Maybe I'll have mercy.

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.
