Answer:
The ligand has only one receptor that it is able to bind to
Explanation:
The shape of the ligand and its corresponding receptor allow there to be specificity. For example, receptors for ligand A would be found on the target immune system cells and not on cardiac muscle cells or skin epithelial cells. Therfore, even though the cardiac muscle cells or the skin epithelial cells would be exposed to ligand A, they would not be able to bind to it and therefore could not react because of the specificity of the receptor of ligand A at that moment
Answer:
B
Explanation:
Arteries and arterioles (small arteries) have muscular walls. They're the main blood vessels involved in vasoconstriction. ... Capillaries are tiny, thin-walled blood vessels that can't constrict.

HOPE IT HELPS ✌️✌️
I will say that the answer to your his question is letter A
The correct answer is C. It is a sudden change that causes species to become extinct.
This answer is not correct because evolution occurs over a long period of time, as evidenced by the theories that describe its timeline (including gradualism and punctuated equilibrium). Additionally, evolution does not always involve the extinction of a species, but it can.
Hope this helps!
