What are the phases in meiosis and explain

Biology
1 answer:

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.

Using the illustration above, why are the chromosomes in two of the sex cells different from the chromosomes in the parent cell?
Misha Larkins [42]

Answer: A  the chromosomes from another parent cell were introduced

Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.

Which best describes the limits of science?
vichka [17]

A. Science cannot answer philosophical questions. Philosophical questions could be described as rheoretical questions, such as "what is the purpose of life?" These questions' answers can very from person to person. Science answers questions such as "what is the boiling point of water?", or "what is the chemical structure of water? These are both questions that have the same answer, no matter who is asking them. You just have to have the ability to accurately measure and observe the things involved, or in this case, the temperature of the water when it starts to boil or whe different atoms in the water.

Let's examine the other questions.

B. science can answer only mathematical questions. As you saw in the explanation above, science can also answer other questions, as long as they have a definite answer that we can accurately measure.

C.Science can answer any questions. Again, we have already saw that science cannot answer philosophical questions, so science cannot answer any question.

D. Science can answer any difficult questions. As with the example of the chemical stucture of water, we can answer difficult questions with science. This may seem simple to you, but it would be very difficult if it was not already known!
