Answer:
True
Explanation:
When the resting potential of the membrane is changed, the membrane becomes either more negative inside or less negative. This small deviation from the resting potential is called graded potential. A graded potential occurs when a stimulus triggers opening or closing of the mechanically gated or ligand-gated channels present in the plasma membrane.
For example, the presynaptic neuron releases neurotransmitters in response to a nerve impulse. The neurotransmitter binds to receptors present in the plasma membrane of the postsynaptic neuron and triggers the opening of the ion channels to allow the inflow of particular ions to flow. The flow of ions changes the voltage across the membrane. This change in membrane voltage is a postsynaptic potential and is a type of graded potential.

Commensalism<span>, in </span>ecology<span>, is a class of relationships between two organisms where one organism benefits from the other without affecting it. This is in contrast with </span>mutualism<span>, in which both organisms benefit from each other, </span>amensalism<span>, where one is harmed while the other is unaffected, and </span>parasitism<span>, where one benefits while the other is harmed.</span>
