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: option d= 130 - 150.
Explanation:
From the question, we are given that the man's age= 50, the man weighs= 193 lb (87.5 kg) and the 50 years old man's resting heart rate= 70 beats · min-1. Then, I am asked to calculate the man's target heart rate (THR) zone for 60% to 80%.
Using the Karvonen (HRR) method to calculate the fifty(50) years old man's target heart rate (THR) zone for 60% to 80%, we will need the man's age for this Calculation and the man's resting heart rate (HR).
Important information to note that is not given from the question is that the 50 years old man's estimated maximum heart rate is (220 - 50) = 170.
Step one: Using the formula; maximum heart rate - man's age × zone Percent. --------------------------(1).
Step two: equation (1) + resting heart rate (HR). -------------------------(2).
For the 60 percent = 0.6.
==>( 170 - 70) × .6 = 60.
Then, 60 + 70 = 130.
For the 80 percent= 0.8;
==> (170 - 70) × .8 = 80.
Then, 80 + 70 = 150.

First aid is care given to someone before a paramedic arrives so for example.. If you and your friend are out on the trails on atvs and your friend wrecks his/her dirt bike and you are miles from the nearest help what would you do? without first aid your friend could die he/ she has a large deep gash in their thigh. It is bleeding bad and applying pressure isn't helping stop it. You remember something from first aid class that may help but your friend could lose their leg and is very scared. so you would try to calm him/her down reassure them and,then you apply a tourniquet to stop the bleeding. now you take your friend to the nearest help. You just saved your friends life but, if you didn't know first aid he/she could've died by the time a paramedic made it to where you were. That is why is important to know. that is what we were taught in my class it worked we all passed and knew how to apply first aid. hope this helped. :)
