Answer:

Resting membrane potential; voltmeter; neuron; interstitial fluid; -70; outside; inside.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

The relative difference in charge across a plasma membrane is the resting membrane potential in an inactive excitable cell. A voltmeter is used to measure the voltage difference across the plasma membrane. This is done by placing one microelectrode into the neuron and the other microelectrode outside the neuron into the interstitial fluid. The RMP has a value that is typically -70 millivolts. More positive ions reside outside a neuron than inside a neuron when it is at rest.
