After a quick search, I was able to find a source with your question and its multiple choice answers

Next time, you should include them, it is helpful! 

"Which describes the action of a ligand's competitive antagonist?"

-A.) It decreases the amount of ligand required to activate the protein.

-B.) It blocks the binding of the ligand to its binding site and prevents activation of the protein.

-C.) It binds to a different binding site on the protein, altering the protein shape so that a ligand cannot bind.

D.) When present, it increases the binding of a ligand to its receptor.

ction potentials typically move in one direction along the neuron away from the cell body. This is due to which of the following
aleksklad [387]

Answer:

The correct answer is option A. "the temporary hyperpolarization of the axon membrane following the action potential spike".

Explanation:

Action potentials, also known as "spikes" or "impulses", are electric impulses that neurons use to send information from the cell's body down to the axon. The impulses are created when ions travel across the neuron's membrane creating a depolarization current. This depolarization current is responsible for an temporary hyperpolarization of the axon membrane following the action potential spike. When neurons are hyperpolarized they are not able to produce another action potential. In consequence, actions potentials move in one direction along the neuron away from the cell body, as well as, adjacent locations go trough similar depolarization processes.

solniwko [45]

The same rabbit population being constant because the food supply is greater in the spring and supporting a larger number of animals is a false statement.

<h3>What is Population?</h3>

This is defined as the total number of organisms in a particular place at a given period of time.

Factors such as topography, human influence are other factors except food supply which influences rabbit population which is why False is the correct choice.
