Impaired brain function as a result of drug use involves all of the following except:
a. increased confusion
b. errors in judgment
c. memory loss
d. increased concentration

Ans:increased concentration. Neural circuits of brain, communicates using neurotransmitters from one neuron to other. Drug's chemical structure mimics neurotransmitter, fools brain, acts as incoming signal. The drug goes and attaches to all signal receiving end of the neurons. When incoming signals are abnormal, all cognitive output signals are affected. Hence confusion arises, there will be problems in judgement, can't recover the deposited memory- an situation of impaired brain function.

Heyhonestly, probably not. humans have always had a tendency to waste things. whether it's food, cosmetic, infrastructure, or our abandoned constructions,the landscape is littered with the refuseof man. archaeology wouldn't be a developed discipline if humans didn't leave things behind. in a way it makes us human

hope it mark me as brainlieast.
