Hello There!
Carbohydrates are the body's primary and most immediate source of energy.
This is because carbohydrates are broken down by an enzyme called carbohydrase into glucose. Glucose is the immediate energy source.
Hope This Helps You!
Good Luck :)

The answer is; Sodium (Na+) and Potassium (K+) Ions
These cations are pumped out of the cell by Na+-K+ transmembrane protein pumps leaving the inside of the cell electronegative in relation to the extracellular matrix. This membrane potential is significant especially for neurons. Depolarization of the membrane enables transmissions of an impulse along the neurons.
Answer:
a. Endocytosis involves the opsonization of a receptor and its ligand in clathrin-coated vesicles, along with the inward budding of the plasma membrane. In exocytosis, waste material is enveloped in a membrane that fuses with the interior of the plasma membrane via attachment proteins.
Explanation:
Endocytosis: entails the external binding of a ligand to its receptor which is located on the external side of the plasma membrane. The membrane buds inwardly for internalization to occur.
Exocytosis: material that has been processed inside the cell is transported by vesicles which fuse to the internal side of the plasma membrane and ultimately transported to the outside of the cell.
Answer:
The correct answer is B. exploitation
Explanation:
Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.
So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.
