Answer:
A) 6
Explanation:
Complex III of the electron transport chain transfers four protons across the membrane during aerobic respiration, per pair of electrons. In the other hand, complex IV is responsible for transporting two protons (per pair of electrons) across the membrane.
If the given compound injects a pair of electron into complex III, four protons will accumulated due to complex III activity and then two more protons as these electrons move forward to complex IV. This means a total of 6 protons being transported to intermembrane space.
Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.

cell; examples are aging, common reason of cancer and also different kinds of diseases.
There’s always a need to have antioxidants because our body needs protection
for the damage by the oxidation may cause.
Answer;
Potential energy
Explanation;
-An object can store energy as the result of its position.This stored energy of position is referred to as potential energy.
-The energy an object has because of its position, rather than its motion. An object held in a person's hand has potential energy, which turns to kinetic energy; the energy of motion, when the person lets it go, and it drops to the ground.
