Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.
More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.
<h3>What is Vasoconstriction?</h3>
This is the process which involves the narrowing of the blood vessels through their muscle wall.
They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

Endocytosis and exocytosis are similar in that they are both forms of cell transport. They differ because in endocytosis, a cell transports molecules into a cell (think: endo - in), and in exocytosis, the cell's molecules are transported by being expelled.
Seafloor spreading can stop during the process, but if it continues to the point that the continent is completely severed, then a new ocean basin is created. Your answer No
