Answer:

The answer is: <em><u> It means it is a membrane that will allow certain molecules or ions to pass through it by means of active or passive transport. </u></em>

Explanation:

All cells are enclosed with a cell membrane. The term, <u>selectively permeable</u>, refers to :

the membrane allows some substances or molecules to enter the cells, and others to be prevented from entering. It also allows substances to leave the cell.

This process can be done by :

Active transport -requires the cell to expend energy to move the materials.

Passive transport- it can be done without using cellular energy.

What type of stimulus is required for an action potential to be generated? What type of stimulus is required for an action poten
Ivahew [28]

Answer:

A threshold level depolarization.

Explanation:

In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.

A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
