Identify the correct statement about the resting membrane potential of a cell. Group of answer choices
1 answer:
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.

Answer:
Option A, a compound that contains carbon atoms bound to other elements
Explanation:
An organic compound is one which has at least one carbon atom that is bonded to several other atoms (may be metallic or non metallic) by a single or double bond is termed as organic compound . The most common atoms with which carbon forms bond are hydrogen, nitrogen,and oxygen.
Some common examples are -
Methane -
Methanol -
Hence, option A is correct
