<h3>Mitosis</h3>
The constancy of the chromosome number from one cell generation to the next is maintained through <u>Mitosis.</u>
<h3>What is mitosis?</h3>
- A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase.
- The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
<h3>What is the mitotic process?</h3>
- A eukaryotic cell's nucleus divides in two during the process of mitosis, which is followed by the division of the parent cell into two daughter cells.
- The term "mitosis," which translates to "threads," refers to the chromosomes' appearance as threads when the cell gets ready to divide.
<h3>What is the phases of the mitosis?</h3>
- prophase
- prometaphase
- metaphase
- anaphase
- telophase, and cytokinesis.
<h3>What is the importance of mitosis?</h3>
- Multicellular creatures depend on mitosis to produce new cells for growth and to replace damaged or worn-out cells, such as skin cells.
- Mitosis serves as the main asexual reproductive mechanism for a large number of single-celled organisms.

Through my research I found questions similar to this with matching choices and they are the following:
A)the membrane potential moves immediately to + 30m V
B)the potassium channels open
C)the sodium channels are inactivated
D)some of the sodium channels at the point of stimulation open
Among those choices, the best answer would be D) Some of the sodium channels at the point of stimulation open.
