What are the fibers that chromosomes move along?
The fibers that chromosomes move along during cell division are called microtubules. These dynamic structures form the mitotic spindle, which helps separate the chromosomes during mitosis and meiosis. The microtubules attach to specific sites on the chromosomes, called kinetochores, and guide their movement to opposite poles of the cell.
Distinguish between mitosis and meiosis?
they both involve the reproducing of cells
The chromosome number is reduced from diploid to haploid during what?
The chromosome number is reduced from diploid to haploid during meiosis. Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells) and involves two rounds of division resulting in four daughter cells, each with half the number of chromosomes as the original cell.
What phase of mitosis do the sister chromatin's separate?
during ANAPHASE each pair of sister chromatids of one x shaped chromosome seperates into two L shaped chromosomes. the chromosomes then move along the spindle fibers to opposite sides of the cellinfo from:LIFE SCIENCEBJU PRESS TEXT BOOK
Why does mitosis continues to occur after you stop growing?
Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
What is meiosis about?
Meiosis is Sexual Reproduction, unlike Mitosis, that is responsible for cell growth and other functions. Meiosis has the same phases as Mitosis except that it undergoes those phase twice (Meiosis l and ll). This results in 4 daughter cells, unlike Mitosis which results in only 2 daughter cells. Also, in Mitosis the daughter cells are identical to the original cell, while in Meiosis, it increases genetic variation, because it has characteristics of both parent cells.
How does the daughter cells produced from meiosis differ from those produced by mitosis?
Daughter cells produced from meiosis are genetically different from each other and from the parent cell, resulting in genetic diversity. In contrast, daughter cells produced from mitosis are genetically identical to each other and to the parent cell. Meiosis involves two rounds of cell division, resulting in four haploid daughter cells, while mitosis involves one round of cell division, resulting in two diploid daughter cells.
What happens during meiosis l and meiosis ll?
During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over, leading to genetic variation. The homologous pairs then separate into different daughter cells. During meiosis II, sister chromatids from the haploid cells produced in meiosis I separate, resulting in four genetically unique haploid daughter cells.
What are the fibers that chromosomes move along?
The fibers that chromosomes move along during cell division are called microtubules. These dynamic structures form the mitotic spindle, which helps separate the chromosomes during mitosis and meiosis. The microtubules attach to specific sites on the chromosomes, called kinetochores, and guide their movement to opposite poles of the cell.
How do you sign the word live?
With both hands in L shapes, move them up the sides of the body from about the hips to about the chest. The L shapes should face the body.
What is the stage of the cell cycle where the nucleus divides?
The stage of the cell cycle where the nucleus divides is called mitosis. During mitosis, the duplicated genetic material in the nucleus is evenly distributed into two daughter nuclei.

How do you calculate the perimeter?
There are many shapes for calculating perimeter such as:Rectangle: 2(L+W) where L=length and W=weightSquare: 4s where s=# givenTriangle and most shapes: add up all the sidesCircle: 2∏r
