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.
Energy is the ability to do work which is stored in the body inform of ATP (adenosine triphosphate). ATP is comprised of a base Adenine, a ribose sugar (5 carbon sugar) and three phosphate groups. when a bond is broken energy is released and when a bond is formed energy is stored. ATP is used by cells as a source of energy such that ATP can easily release or store energy by breaking the chemical bonds and reforming the bonds between its phosphate group. The correct answer is c, phosphate- phosphate bond
Biotic factors are the living things in any environment, while abiotic factors are the nonliving things.
So, in the Sahara desert the living things (biotic factors) would be the animals and plants.
The nonliving things (abiotic factors) would be the sunlight, temperature, dirt, etc.
