Which process maintains homeostasis by replacing cells that die or get damaged? cell division cell respiration excretion photosynthesis

Cell division

Explanation:

Cell division is the process by which a mother cell originates daughter cells. Through this process unicellular cells reproduce and multicellular cells multiply.

The frequency of cell division varies with the type and physiological state of each cell.

In the human organism, for example, some cells are constantly multiplying to replace deficient cells. An example is the epidermis and bone marrow cells, which multiply to replace the dying cells. However, some more specialized cell types, such as neurons, red blood cells and muscle cells, never divide.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
