sweet-ann [11.9K]

Answer:

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes.

Anaphase is the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.

Telophase is the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.

Cytokinesis is the division of cells after either mitosis or meiosis I and II.

What happens to the bunny population if a friend is never added? What happens when you add a friend
pochemuha

While pet rabbits can survive alone without another bunny living with them, they can get very lonely and sad, as rabbits are naturally herd animals. No matter how much human attention they receive, that does not replace attention from a fellow rabbit friend.

When one rabbit is introduced to another rabbit, they may not always get along. However, they will always be very curious when they first meet, and can become close friends after bonding for a while. Keeping close supervision on bunnies when they first meet, however, is very crucial, as they could get into a fight and hurt each other.

The diagram below represents a flower, the reproductive structure of some plants. Most
Evgen [1.6K]

Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

<u>The structure represented by the letter A in the diagram is the stigma.</u>

The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
