Which event most accurately describes cytokinesis?

Biology

Talja [164]3 years ago

Cytokinesis is the process wherein actual division of the cell, including the cell membrane and the cytoplasm, from the parent cell to two daughter cells. The correct answer in this question is "the metaphase plate is the beginning area for cytokinesis" as the metaphase plate dictates the midpoint of the cell. A cell with a cell wall (plant cell, for example) cannot perform cytokinesis with a cleavage furrow but with a cell plate. Phragmoplast only develops in plant cells. Lastly, cytokinesis only starts after telophase.

Answer:

The correct answer would a. cell walls prevent cleavage furrow from deepening.

Cytokinesis refers to the division of cytoplasm of a parent cell into two daughter cells.

In animal cells, the cytokinesis is achieved with the help of cleavage furrow. The contractile ring of actin filament is formed below the cell membrane that constricts the middle of a dividing cell in order to complete the cell division.

In plant cells, due to the presence of a cell wall, cytokinesis takes place with the help of cell plate formation instead of a contractile ring.

Formation of cell plate takes place along the equator of the dividing cell. New cell membrane and cell wall are formed along each side of the plate in order to divide the parent into two daughter cells.

What would most likely happen to the chipmunk population in 2014 if the population went up to 22 million in 2013?
gulaghasi [49]

Answer: The chipmunk population would crash.

This is because the population would reach carrying capacity. This way, the resources would be strained and unable to support the high Chipmunk population. The increased competition for meager resources between the Chipmunks would result in increased deaths rate of individuals that is higher than the birth rate.

_____ develop in two phases: (1) blood vessels in the brain narrow, so that the flow of blood to parts of the brain is reduced,
vovangra [49]
The answer for the question is Migraine<span>. Migraines Headaches are extremely, nearly paralyzing headaches that are located on one side of the head and are sometimes accompanied by dizziness, nausea, or vomiting. They normally develop in two phases; The first phase, in which blood vessels in the brain narrow (vasocontsriction), such that the flow of blood to arts of the brain is reduced. Second phase; occurs when the blood vessels expand, such that blood flows through them rapidly, thus stimulating many neuron endings and causing pain. </span>

how do i describe the second part of anaphase one the cell cycle? as in after the division of chromosomes.
loris [4]

Answer:

<h2><u><em>I think this will help u with the answer that ur looking for. I hope so</em></u></h2>

Explanation:

<h3><u><em>Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the equator of the cell on the equatorial plane. The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. </em></u></h3><h3><u><em> </em></u></h3><h3><u><em>During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. </em></u></h3><h3><u><em> </em></u></h3><h3><u><em>Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase. </em></u></h3><h3><u><em> </em></u></h3>
