There is a much greater surface area for the exchange of oxygen and carbon dioxide.
Answer:
During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.
Explanation : Replication of DNA does not occur in mitosis. Replication of DNA occurs during S phase, an entirely different phase of cell division.
Explanation:
The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell.
Anaphase. The sister chromatids separate from one another and are pulled towards opposite poles of the cell. The microtubules that are not attached to chromosomes push the two poles of the spindle apart, while the kinetochore microtubules pull the chromosomes towards the poles.
Answer:
The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops. The word filament is from the Latin word filum, which means "thread." Filament, in fact, can be a synonym for thread.
