Astudy of the relationship between exercise and heart attacks that is conducted among men who do not smoke. is gender a confounder in this study?

The answer to this question would be: true

Gender should be confounding factor because it can influence the dependent and independent variable in this case. Male is known to have a higher incidence of cardiovascular disease. The ratio of smoker is also much higher in male than female.

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature

The  correct answer should be a waste
