Explanation:
Equilibrium potential of ions is the difference of electric potential in the cell membrane that equilibrates the concentration gradient of an ion.

Explanation:
Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.
<u>It includes the following phases -
</u>
1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .
2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .
3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .
4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.
5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.
6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
