Question 1

The sequence of events in meiosis II is prophase II,________,anaphase II,and telophase II,which is accompanied by cytokinesis.

Accepted Answer

The answer of The sequence of events in meiosis II...

Question 2

Unlike mitosis,during meiosis II,the nuclear membrane does not break down.

Accepted Answer

During meiosis II, the nuclear membrane does break down. This allows for the separation of sister chromatids during the second round of division.

Question 3

All cells in a human body undergo the process of meiosis.

Accepted Answer

Meiosis is a specialized type of cell division that occurs only in the reproductive organs of the body, such as the testes and ovaries. It is responsible for producing gametes (sperm and eggs), which contain half the number of chromosomes as the parent cell. All other cells in the human body undergo a different type of cell division called mitosis.

Question 4

The daughter cells that are produced in meiosis I are haploid.

Accepted Answer

In meiosis I, the homologous chromosomes separate, resulting in two daughter cells that are haploid.

Question 5

The goal of ________ is to increase genetic diversity by creating a new diploid individual from haploid cells that are derived from two different individuals; the aforementioned haploid cells join together to make a zygote during a process called ________.

Accepted Answer

The answer of The goal of ________ is to increase...

Question 6

The procedure that enables a young woman to freeze her eggs when she is single and save them for later use,up to age 50,is called ________.

Accepted Answer

The procedure is called egg freezing or oocyte cryopreservation. It allows women to preserve their fertility and have the option of having biological children in the future, even if they are not ready to start a family at the present time. The process involves harvesting a woman's eggs, freezing them, and storing them until she is ready to use them, up to age 50.

Question 7

Interphase is an uneventful resting stage of the cell division cycle.

Accepted Answer

Interphase is an active phase where the cell grows, duplicates its DNA, and prepares for cell division, not just a resting stage.

Question 8

At the end of telophase,the cell is ready for physical division into two cells; this process is called ________.

Accepted Answer

The answer of At the end of telophase,the cell is...

Question 9

The events in meiosis I are almost identical to the events in mitosis.

Accepted Answer

The events in meiosis I involve unique processes, such as crossing over between homologous chromosomes and the separation of homologous pairs. In contrast, mitosis involves the separation of sister chromatids.

Question 10

During prophase,the opposite ends,or spindle poles,of a cell that is beginning mitosis are determined by the separation of the ________.

Accepted Answer

The answer of During prophase,the opposite ends,or spindle poles,of a...

Question 11

New nuclei form during the anaphase stage of cell division.

Accepted Answer

New nuclei form during the telophase stage of cell division, not anaphase. During anaphase, sister chromatids are separated and pulled to opposite poles of the cell.

Question 12

Cytokinesis and mitosis are the same processes.

Accepted Answer

Cytokinesis and mitosis are two separate processes. Mitosis is the process of nuclear division, which results in two identical nuclei, while cytokinesis is the division of the cytoplasm, resulting in two separate daughter cells. Together, mitosis and cytokinesis make up the process of cell division.

Question 13

If a skin cell of an organism has 24 chromosomes,its gametes must also have 24 chromosomes.

Accepted Answer

Gametes undergo meiosis, a process of cell division that reduces the number of chromosomes in half. Therefore, gametes of this organism would have only 12 chromosomes.

Question 14

A zygote contains 16 chromosomes.The diploid number of this cell is ________ [2n = ?].

Accepted Answer

The answer of A zygote contains 16 chromosomes.The diploid number...

Question 15

The mitotic spindle guides the movement of chromosomes during certain stages of mitosis.

Accepted Answer

The mitotic spindle is integral in pulling sister chromatids apart and distributing them evenly to the daughter cells during mitosis.

Question 16

During meiosis I,the microtubules from each spindle pole attach to only one member of a bivalent,generally the one closest to that spindle pole.

Accepted Answer

This is called "monopolar attachment" and it ensures that each homologous chromosome is pulled toward a different spindle pole during meiosis I, allowing for their separation and independent assortment.

Question 17

One way to create genetic diversity is through the random distribution of chromosomes into daughter cells during the meiotic stage of ________.

Accepted Answer

The answer of One way to create genetic diversity is...

Question 18

The four cells that result from meiosis are not diploid like the cells produced by mitosis; instead,they are ________.

Accepted Answer

The answer of The four cells that result from meiosis...

Question 19

Cytokinesis occurs during interphase.

Accepted Answer

Cytokinesis occurs after mitosis during the M phase of the cell cycle, not during interphase which consists of G1, S, and G2 phases.

Question 20

Microtubules attach to plaques of protein on chromosomes; these plaques are called ________.

Accepted Answer

The answer of Microtubules attach to plaques of protein on...
