Which one of these is not an example of intercellular communication?

a molecule stimulates a target cell via a receptor.

a message is distributed across plasma membrane.

a message travels between gap junctions.

an electrical signal causes muscle cells to contract together.

The answer is A Message Is Distributed Across Plasma Membrane

Explanation:

This is not an example of intercellular communication because When a message is transferred across plasma membrane this means that no other cell is involved in it. The message is transferred from one organelle to other within the cell. Inter cellular response is not restricted only upto a single cell.

the answer to this question is a

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
