Coach taylor is trying to explain the negative side effects smoking has to athletic performance. which of these options include both a scientific model and a connection to coach taylor’s topic of athletic performance?
a.
show pictures of the lungs of a smoker as compared to a non-smoker
b.
write the chemical formulas for carbon monoxide (found in tobacco smoke) and oxygen, comparing the two substances
c.
diagram the flow of oxygen-rich blood through the body of a non-smoker. then diagram the flow of blood with less oxygen (from airway resistance) through the body of a smoker
d.
list some diseases linked to smoking: cardiovascular disease, lung cancer, emphysema

a.

Show pictures of the lungs of a smoker as compared to a non-smoker

c. Diagram the flow of oxygen-rich blood through the body of a non-smoker. Then diagram the flow of blood with less oxygen (from airway resistance) through the body of a smoker

Explanation:

Cigarette has about 4,720 substances. There are three of them that greatly compromise the athlete's performance: nicotine, which reduces the size of the arteries, which take the blood to the muscle, generating a much lower muscle performance, and also increases the heart rate; tar, which reduces lung elasticity; and carbon monoxide, which competes with oxygen, which is why the person who smokes has shortness of breath.

For this reason, Coach Taylor, was explaining to his team how important it is that they don't smoke if they want to be good athletes. A great way for the trainer to represent the importance of athletes staying away from smoking is to make a diagram of the flow of oxygen-rich blood through the body of a non-smoker. Then he can make a diagram of the blood flow with less oxygen (from the airway resistance) through a smoker's body.

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15
