When you change from a low-power objective lens to a higher-power one, what happens to the field of view? Does it increase or decrease?
Decreases with increasing maginfication
In terms of heart rate and exercise, which one is the dependent variable and which one is the independent variable?
Dependent=heart rate. Independent= Exercise.
