During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were. Simplisticly said During chemical reactions, the chemical bonds between atoms are altered.
Upwelling is a process in which cold water from depths arise to the surface,
it's important because :

The cell membrane forms a barrier that keeps all substances that might harm the cell from entering the cell. (Pls mark me as brainliest!)
Answer: Both vasoconstriction and vasodilation.
Explanation:
The mechanism that controls the blood flow to various parts of the body is vasoconstriction and vasodilation.
Vasoconstriction can be defined as the phenomenon in which blood vessels decrease in diameter to decreases, the pressure in the blood vessels also increases which in turn increases the blood flow.
Vasodilation can be defined as the phenomenon in which the diameter of blood vessels increases and the pressure in the blood vessels decrease and blood flow decreases.
This increases and decreases the blood flow so as to make the blood reach each and every part of the body.
