It is known as adrenaline rush.

Explanation:

Adrenaline rush refers to a sudden emergence of energy resulting due to an enhancement in the hormone and the neurotransmitter epinephrine or adrenaline. It may comprise an upsurge of heart rate, perspiration, blood sugar content, blood pressure, and metabolism.  

Adrenaline is considered as the fight or flight hormone. It is discharged in response to an exciting, stressful, threatening or dangerous circumstance. It helps the body to react more briskly. If the hormone gets discharged quite enough, the body then starts to remember the old connected feelings that can eventually result in a serious addiction.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
