The people that interfere with cytokinesis in the cells of dividing animals are gene mutations that encode actin.
<h3>How does cytokinesis occur in animal cells?</h3>
Cytokinesis occurs in anaphase in animal cells and prophase in plant cells, then ends in telophase (both in animals and plants). Cytokinesis is the division of the nucleus into two equal parts, each of which contains an identical set of diploid chromosomes to the parent cell.
Cytokinesis in animal cells begins with a groove that occurs right on the cell surface in the equatorial region. On the surface of the cell, there is a contractile ring formed by contracting actin and myosin microfilaments

Answer:
In meiosis I there is prophase I, metaphase I, anaphase I, and telophase I and then in meiosis II there is prophase II, metaphase II, anaphase II, and telophase II.
Explanation:
In meiosis I we have;
Prophase I in which a pair of homologous chromosomes line up and form a tetrad. This is the stage during which genetic recombination occurs.
Metaphase I occurs, during which the homologous chromosomes line up opposite each other at the metaphase plate. The chromosomes orientate themselves randomly, thus homologous chromosomes are distributed randomly to daughter cells .
In Anaphase I, homologous chromosomes move to opposite sides of the cells but sister chromatids remain together. Each cell now has 23 chromosomes.
Telophase I in which the homologous chromosomes move to the poles and cytokinesis occurs. Two daughter cells are formed.
In meiosis II we have;
Prophase II (note: there is no interphase as seen in mitosis) during which chromosomes start to move to the metaphase II plate. There is no replication.
Next is metaphase II when the chromosomes align at the metaphase II plate.
In anaphase II the sister chromatids separate from each other and move towards opposite poles.
Lastly, in telophase II cytokinesis occurs again and four daughter cells are produced. Each of the four daughter cells has 23 chromosomes.
Blocks, Since water blocks sunlight, photosynthesis can't occur in deep waters, because sunlight is required for photosynthesis.
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.

They have to find different food because its normal choices of food arent avalible during cold tempatures. They have to go into hiding and prepare for this change.
