What is current :

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. ... Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current.

what is mitosis :

The division of a cell of the body that results in two cells, each with the same number of chromosomes as the original cell

What is Mitosis

\huge\bf\underline\pink{Answer࿐}

In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei.

Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.[1] In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.

The different stages of Mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.

What is current

\huge\bf\underline\pink{Answer࿐}

  • An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
  • It is measured as the net rate of flow of electric charge through a surface or into a control volume.:2:622 The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor.
  • In electric circuits the charge carriers are often electrons moving through a wire.
  • In semiconductors they can be electrons or holes. In a electrolyte the charge carriers are ions, while in plasma, an ionized gas, they are ions and electrons.
