Answer:D. they are all small molecules

Explanation:Tight cell-wall junctions and a layer of cells around the blood vessels keep large or electrically charged molecules from entering the brain. However, small neutral molecules like those of cocaine and MA easily pass through the blood-brain barrier and enter the brain. Once inside the brain, substances of abuse begin to exert their psychoactive effects.

Which of the following activities were most likely help Anthony manage the stress level?
just olya [345]
Technically any of these. Are there any other details or specifics. I'd assume participating in sports because a diet only helps stress levels in the long term, watching television can relax a person but the other factors such as lack of social activity can contribute to a person's overall mental state and therefore increase stress levels, and studying can actually be relieving for some people depending on the mental state and needs of them but can obviously be a stresser. The only downfall to participating in sports is getting to excited or emotional during a game for example. But overall, C is the best choice.
