Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

<u>Answer:</u>
<em>Mitochondria appear in the greatest numbers in cells that are</em><em> </em><em><u>Muscle cell.</u></em>
<u>Explanation:</u>
Mitochondrion is the power house of the cells. It releases the energy need for the cells. So mitochondrion is found in large number in muscle cell because muscles are the component of our body that needs large amount of energy.
Muscles need to be frequently moved in our body so large number of mitochondria helps in providing the enough energy for the proper muscle movement.
