I believe it is A. because hypothesis is an eduated guess, usually with limited evidence.<span />
The answer is formation of spindle fibers.
Asters (Latin word for stars) of centrosomes are microtubules and are formed around centrosomes during mitosis. During prophase, asters and centrosomes move to the opposite sides of the cell. During metaphase, asters extend and connect to the centromere of chromosomes. During anaphase, those microtubules pull the chromatids apart to the centromeres on the opposite sides of the cell.
Oxygen because lipids are fats that need oxygen to use long term energy
During telophase of Mitosis nuclear membranes of two separated nuclei are formed around each set of chromosomes.
<u>Explanation</u>:
Mitosis is the process of cell division part of the cell cycle. Mitosis is classified into four phases which are prophase, metaphase, anaphase and telophase. In prophase the nucleolus disappears, chromosomes start to contents and the mitotic spindle starts to appear and bind to the kinetochore of centromere of the chromosomes. In metaphase nuclear envelope breaks down and the chromosomes becomes fully condensed and organized on the metaphase plate in the middle of the nucleus, during anaphase chromosomes are pulled back to their centromeres with the help of spindle fibers and during telophase the chromosomes starts to decondense, the nucleous reappears and nuclear membrane reforms and spindle starts to disappear.
