The correct processes and components of the carbon cycle is given in the image attached .
Both lipids and carbohydrates are important in animal cells because store energy. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Carbohydrates on the other hand have six major functions in the body; including providing energy and regulation of blood glucose, sparing the use of proteins for energy, breakdown of fatty acids and preventing ketosis.
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.

Answer:
Nucleus: The nucleus controls everything which takes place in the cell. It does this as it is the site of the cell's DNA. DNA contains the genetic code which is translated into proteins.
