Chromosomes move rapidly toward the mitotic centers during what phase?
During prometaphase, chromosomes rapidly move towards the mitotic centers in preparation for cell division. This movement is driven by microtubules attaching to kinetochores on the chromosomes, which help to align the chromosomes at the metaphase plate for proper segregation.
Does mitosis occur at the same rate in all different parts of an organism?
No, mitosis does not occur at the same rate in all parts of an organism. Different tissues and organs have varying rates of cell division depending on their function and need for growth or repair. For example, rapidly dividing tissues like skin or intestinal cells undergo more frequent mitotic divisions compared to cells in a more static tissue like muscle.
How many chromosomes does algae have?
algae, can have as many as 140 chromosomes
How many times does mitosis happen in a day?
The number of times mitosis occurs in a day depends on the specific type of cell and its growth rate. In rapidly dividing cells, such as those in the bone marrow, skin, or intestinal lining, mitosis can occur multiple times per day. In general, human cells undergo mitosis on average once a day.
Why is it necessary to have both mitosis and meiosis?
Mitosis is used for several purposes 1. Growth. the embryo increases in size due to mitosis. Enlargement of the embryo, young child and growth during puberty is due in part to increasing the number of cells. 2. Repair. If you cut yourself, or an incision is made during surgery, the hole is closed by cells dividing to close the space created by the wound. 3. Replacement. Some cells wear out rapidly (blood - 90-120 days; skin - 2 weeks; intestine 2.5 days) these old and worn out cells need to be replaced on a constant basis 4. Reproduction - protists that undergo mitosis have produced two identical cells and thus have reproduced 5. Cancer - unfortunately cancer is mitosis of cells that we don't want to be undergoing mitosis. Meiosis is used to produce the sperm and the egg each of which have half the number of chromosomes as the starting cell. This is so that when a sperm fertilizes an egg the total number of chromosomes is equal to that in any other cell

Chromosomes move rapidly toward the mitotic center during what?
centeromes
How do single -celled organism use mitosis?
Yes. During mitosis, interphase takes place with a single-cell, then follows up with prophase, then metaphase where the chromosomes line up within the center of the cell. Next, follows anaphase- which is when the chromosomes are pulled in opposite directions toward the pulls with aid of the spindle fibers. Then comes telophase where the cell begins to get ready for the 'split' which is when the 'pinch' starts to form. During the end of telophase and completion of cytokinesis, the cell fully breaks apart, forming two identical daughter cells from the one parent cell it started out with.
Out of control mitosis forms large numbers of rapidly dividing called a?
tumor.

What state has the most drug rehab centers?
California has the most drug rehab centers due to its high rates of drug addiction and alcoholism. Not only does it has the most drug rehab centers, the numbers of centers are rapidly increasing.
Why is onion good to observe mitosis?
Onions are commonly used to observe mitosis because their root tips contain rapidly dividing cells, making it easier to identify the stages of cell division. The tips are also rich in meristematic tissue, where cells are actively dividing. Furthermore, the large size of onion cells allows for clear visualization of the chromosomes during various phases of mitosis. This makes onions an ideal specimen for studying the process of cell division in a classroom or laboratory setting.
Why do mitosis and mitosis need to occur?

Does mitosis occur at a slower rate in baby humans?
If you are referring to the rate of mitosis compared to adult humans, then no, mitosis actually occurs faster in infants and toddlers than in adults. This increase of speed causes a large amount of growth, whereas an adult may have more cells that will not reproduce as fast without any immediate injuries.But comparing with other animals the process of mitosis is slower in the mammels
Why would it be helpful in the treatment of tumors if medication that is designed to prevent mitosis in certain cells?
Medications that prevent mitosis can be helpful in treating tumors because they target rapidly dividing cancer cells, which rely on mitosis for growth. By inhibiting mitosis, these medications can slow down or stop the progression of the tumor, leading to its shrinkage or elimination. This can be an effective strategy in cancer treatment.
Name at least one place in your body where mitosis is currently taking place?
Mitosis is the process of cell division. This occurs in many places in your body, but most rapidly in areas that turn over cells often like the gut and skin. These are the tissues with the most rapid rates of mitosis.
What factors might influence the magnitude of the mitotic index?
The magnitude of the mitotic index can be influenced by several factors, including the phase of the cell cycle, tissue type, and external stimuli such as growth factors or stressors. Higher mitotic indices are often observed in rapidly dividing tissues, like cancerous cells or embryonic tissues, while quiescent or differentiated cells exhibit lower indices. Additionally, environmental factors like nutrient availability, temperature, and exposure to toxins can also affect cell division rates and thus the mitotic index.
