Answer:Adhesion
Explanation:Is the attraction of water molecules to other molecules of different substances. Water molecules are said to be polar which means that the molecule has a slightly negative charge and a slightly positive charge. This property of water allows it to interact with other polar or charges substances making it attract to other molecules.
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
