Analyze the table illustrating the events of mitosis and cytokinesis. The table outlines the potential activity of the chromosomes and
the dividing cell in which cell cycle stages are the events that are listed accurate? Select ALL that apply.
A) anaphase
B) cytokinesis
C)metaphase
D) prophase
E) telophase
Answer:
metaphase & telophase
Explanation:
Just did the same question
The possible movement of chromosomes and the cell dividing into the metaphase and telophase cycle phases are the events that are accurately listed. So, the correct options are C and E.
What are the phases of Mitosis?Mitosis consists of five morphologically distinct phases which are as follows: prophase, prometaphase, metaphase, anaphase and telophase where each phase involves specific steps in the process of chromosome alignment and segregation.
Metaphase is defined as the chromosomes that line up in the middle of the cell while telophase is defined as the two nuclei that form after the reformation of the nuclear envelope around each set of chromosomes.
Thus, the possible movement of chromosomes and the cell which divides into the metaphase and telophase cycle phases are the events that are accurately listed. Therefore, the correct options are C and E.

desert, grassland, taiga, temperate, rainforest.
What are different biomes in the world?Terrestrial (land) and aquatic (water) biomes are the two broad categories into which we might divide biomes.
Let's study about the nine major biomes that make up the earth, according to the 9–20 biomes: Tropical Rainforest, Temperate Forest, Desert, Tundra, Boreal Forest or Taiga, Grassland, Savannah, Freshwater, and Marine.
Due to the high latitudes at which these regions are found, tundra is known to be the coldest biome of all. The low temperatures in this biome restrict the growing season of the trees to the summer, which also limits their growth.
Therefore, Taiga regions are also known as boreal woods, since they are a type of biome made up of forest that can be found in subarctic climates.

8. Sea breezes occur during hot, summer days because of the unequal heating
rates of land and water. During the day, the land surface heats up faster than the
water surface. Therefore, the air above the land is warmer than the air above
the ocean. Now, recall that warmer air is lighter than cooler air. As a result,
warm air rises. Therefore, the warmer air over the land surface is rising. As the
warm air over the land is rising, the cooler air over the ocean is flowing
over the land surface to replace the rising warm air. This is the sea breeze
and can be seen at the top of the following image. The bottom of the following
image illustrates the land breeze that occurs at night. Recall that the land surface
cools quicker than the water surface at night. Therefore, the warmer air over the
ocean is buoyant and is rising. The denser cool air over the land is flowing
offshore to replenish the buoyant warm air and is called a land breeze.
Why do you think, in our coast, during summer we feel an ocean breeze flowing into
the land.
As the warmer air from the land rises cool air rushes towards the shore to replace it which is why we feel a cool breeze at the ocean
