Animals do not keep all their detoxification enzymes in aconstant state of readiness. Thus they depend on phenotypicplasticity to adapt to changing hazards. An example is providedby the enzyme alcohol dehydrogenase, which breaks down ethylalcohol. People who do not drink alcoholic beverages have littlealcohol dehydrogenase. Expression of the enzyme increaseswhen people drink alcohol, but full expression requires manydays, meaning that people are incompletely defended againstalcohol’s effects when they first start drinking after a period ofnot drinking. Consider, also, that muscles atrophy when notused, rather than being maintained always in a fully developedstate. Propose reasons why animals depend on phenotypicplasticity, instead of maintaining all their systems in a maximumstate of readiness at all times.
