Answer:
B. Leslie had more dopamine receptors than other participants.
Explanation:
Ritalin (methylphenidate hydrochloride) is a central nervous system stimulant drug used to treat Attention Deficit Hyperactivity Disorder (ADHD). Ritalin also serves to treat narcolepsy, a sleep disorder that is characterized by excessive daytime sleepiness, even if the person has slept well at night.
Ritalin increases the activity of certain areas of the brain that are poorly active, promoting increased attention and concentration, and decreasing impulsive behavior. In narcolepsy, Ritalin works by relieving sleep throughout the day. The mechanism of action of Ritalin is the same as that of amphetamines and other stimulants, ie it increases the concentration and reuse of neurotransmitters such as dopamine and norepinephrine in the brain. For this reason, people with more dopamine receptors in their brain (such as Leslie) when taking ritalin feel pleasant feelings.
Answer:
DASH (Dietary Approaches to Stop Hypertension)
Explanation:
Due to ever increasing cases of hypertension in United States, DASH or Dietary Approaches to Stop Hypertension was created. It aims at lowering blood pressure with dietary changes and without the use of medication.
It recommends to increase the quantity of vegetables, fruits, nuts and whole grains in diet. These are good sources of carbohydrates, proteins and fats. It also recommends to reduce the salt or sodium, sugar and red meat content in diet. These ingredients are present in very high amounts in typical US diet and they are responsible for hypertension. By following DASH, systolic blood pressure can be reduced by eight to fourteen points over the course of time.
