Im going to use a cactus as an example. A cactus is a plant that lives in hot, dry climates, which has needle like leaves to protect itself from animals searching for water. It has a thick waxy curticle to make it hard for an animal's teeth to pierce the plant and to help keep the water in the plant (the heat makes it easier for the plants water to be used up at a quicker pace).

The autorhythmicity of cardiac pacemaker cells is made possible by the reduced permeability of _______. The autorhythmicity of c
vichka [17]

Answer:

<h2>potassium</h2>

Explanation:

The heartbeats of the heart are controlled by the sinoatrial node also known as the pacemaker of the heart. The impulse is generated in the conducting cells of the pacemaker as a result of the movement of sodium, potassium and calcium ions.

The sodium channels allow the movement of sodium into the cell which depolarizes the membrane from -60mv to -40 mv. At this point, the calcium gated channels open which allow the entry of the calcium in the cell which depolarizes the cell up to +5mv.

At this point, the potassium channels open which allows the potassium ions to move out of the cell. This repolarizes the cell and hence the cycle again begins.  Reducing the permeability of the potassium ions help generate the autorhythmicity due to repolarization and thus is the correct answer.
