Every time alcohol is presented into the system, the biphasic effect, or “biphasic curve,” follows. The biphasic is a two phase effect: first, the body experiences an energizing, perhaps “positive,” component and second followed by the introduction of the depressant, “negative,” effects of alcohol. There is a point at which one can minimize the undesirable consequences associated with drinking. In other words, drinking beyond this point will outcome in enlarged negative consequences. This means for college students, that students who currently drink at or below this point of diminishing returns should stay at this point if they haven’t had problems associated with drinking. Those who are drinking further than this point should reflect reducing their intake to maximize their returns. Most significantly, everyone has to find his own limit grounded on what he wants to get out of drinking.
Answer:
d. Cnidarians and comb jellies, only two germ layers are formed
Explanation:
Diploplastic animals are the animals which do not have three germs layer so rather than three they are made up of only two germ layer which is ectoderm and endoderm. Mesoderm is absent in them so they do not have true coelom or body cavity.
So as cnidarians and comb jellies are formed from only two germ layers that are endoderm and endoderm, therefore, they are called diploblastic. Fish, amphibians, reptiles, and mammals are triploblastic animals. So the correct answer is d.
