What does not belong centrioles vesicles kinetochore fibers polar fibers?
vesicles because the rest are all part of prophase.
What happens during late prophase?
The late prophase is one of the stages in mitosis and during this stage there is a break up of the nuclear envelope and the microtubules that the spindle fibers are made up of called the polar fibers reach from the pole to the equator of each cell. Specialized regions that are in the centromeres of chromosomes called Kinetochores attach to kinetochore fibers which are a type of microtubules. The spindle polar fibers connect the polar fibers to the kinetochores through their interaction with the kinetochore fibers and the chromosomes start to migrate towards the center of the cell.
What is the function of microtubules during anaphase?
During the first stage of anaphase the kinetochore microtubules retract pulling the two sister chromatids apart towards the poles. During the second stage of anaphase the mitotic poles that is mared by the centrosomes themselves separate by the elongation of a specific type of non-kinetochore microtubule called as the polar microtubule.
Describe the structure and function of the spindle during mitosis?
Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.
What is a relatively weak bond between polar molecules?
A polar molecule is positive on one end and negative on the opposite end. A hydrogen bond is a special attraction between polar molecules, a weak bond.
Two types of fibers in fibrocartilage?
Polar and kinetochore. Polar are what 'push' the poles apart, while kinetochore connect at the kinetochore and the centrosome.

What distinguish between polar and non polar dielectrics?
b c polar molecules are easily soluable in water thanthe non polar molecules
The fibers that extend from centrosome to centrosome during mitosis are what?
microtubles made from the lateral association of alpha and beta tubulin dimers
What is polar fleece knit or woven?
I would say that polar fleece is a woven fabric, made with synthetic fibers.
How are chromosomes connected to the chromatid?
Chromosomes are composed of two chromatids. Each chromatid is an exact replica of the other, and for this reason they're called sister chromatids. If the chromosome is an "X", then the left side is one chromatid and the right side is the other. Eventually the centromere will split in the middle of the "X" and the sister chromosomes will move towards the polar ends of the cell via kinetochore fibers.
What is polar fleece made of?
Polyethylene terephthalate (PET) or other synthetic fibers.
What is the function of microtubules during anaphase?
During the first stage of anaphase the kinetochore microtubules retract pulling the two sister chromatids apart towards the poles. During the second stage of anaphase the mitotic poles that is mared by the centrosomes themselves separate by the elongation of a specific type of non-kinetochore microtubule called as the polar microtubule.

What type of intermolecular forces predominate between cellulose fibers?
From what i can tell, hydrogen bonding is the dominate force between cellulose fibers. The exposed OH groups on the ends of the molecule attract oxygen. This is why cotton and other fibers made from Cellulose absorb water well; the exposed OH groups attract the oxygen on the water molecule. You may want to double check though...I am not a Chemistry expert by any means.
Why CCL4 is polar?
It is not polar. only the bonds between the chlorine and carbon are polar
