Mitosis is a type of cell division in which single parent cell divides into two daughter cells with equal number of chromosomes as in the parent cell.
It occurs in somatic cells of the body for growth and repair of the tissue.
It maintains the chromosomal number between parent and daughter cells and it is the reason that it is also called as equational division.
Plant uses sun energy to convert the carbondiode into energy
The answer is D: poaching, since it harms wildlife and destroys ecosystems.
Answer:
The inhibitory transmitter activates ligand-gated potassium channels
Explanation:
When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.
However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
