Which of the following statements about plankton or nekton is NOT correct?
Oduvanchick [21]

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.

Choose the statement that describes processes of receptor-mediated endocytosis, exocytosis, and the changes in the membrane orga
Elis [28]

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.
