Answer:C
Explanation:
Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.
It has a value of -50 and -75mV.
Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)
In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .
These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.
The movements of these ions across the membranes generated electrical potential difference for action potential.
White blood cells help to fight off infection and then begins to repair the wound. This would take about 2-5 days to start healing
The tapeworm is a parasite, and the dog is a host.
