Explanation:
option 5 is not correct as viruses are acellular organisms.
Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
The answer is A, redshift
<span>The answer to this question would be: b. constricting the blood vessels
</span>
Vasopressin can constrict the arteriole and reduce urine production by increasing the absorption in the renal tubule. When arteriole blood vessel constricts, the diameter of the vessel will be reduced. A smaller diameter will result in an increased peripheral resistance and cause the blood pressure to be increased.
Vasopressin doesn't affect the blood natrium level.
