Answer: The correct answer is option C
FACILITATED DIFFUSION.
Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).
Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.

<h2>The Cardiac cycle</h2>
Explanation:
Correct order is: 3,5,6,4,2,1,8,7
The cycle of events that happen in a single heart beat is called Cardiac cycle. Basically, it refers to repeated pattern of contraction and relaxation of the heart.The contraction of heart is called systole and the relaxation of heart is called diastole. The cardiac cycle includes systole and diastole of atria as well as systole and diastole of the ventricles. When heart rate is about 75 beats per minute, a cardiac cycle takes 0.8 seconds.
The order of events is cardiac cycle is :
- beginning of atrial systole
- completion of ventricular filling.
- beginning of ventricular systole.
- closure of AV valve.
- isovolumic contraction.
- opening of semilunar valve.
- ventricular ejection.
- ventricular relaxation.
There must be a membrane and cytoskeleton. Hope this helped!
