Answer:
c. Biosphere
Explanation:
The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It contains all living things above and below the surface of the Earth.
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
<h3>
How the neuron get stimulus?</h3>
When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

Answer:the cell divides by mitosis
Explanation:in this process the cell divides into two identical cells called the daughter cells.the daughter cells end up with the same amount of chromosomes in their nucleus like the parent cells .
Mitotic division involves four stages;prophase, metaphase,anaphase and telophase.
In prophase,the chromosomes shorten and thicken.homologous chromosomes join to become chromatids
In metaphase,the chromatids arrange themselves at the equator of threadlike spindle fibres
In anaphase,the chromatids separated and move to opposite ends of the cell
In telophase, the spindle break down,the chromosomes lengthen and the cytoplasm of the cell divides into two.
this leads to growth and replacement of cells
