In an experiment, a student used a respirometer to measure the oxygen consumed by 5 g of germinating seeds over 30 minutes. The capillary tube showed a fluid movement of 25 mm, and the cross-sectional area of the tube was $0.5 \ mm^2$. What volume of oxygen was consumed?

Question

Accepted Answer

$12.5 \ mm^3$. The volume of oxygen consumed is calculated as: Volume = length of fluid movement × cross-sectional area of the capillary tube. Therefore, Volume = 25 mm × 0.5 mm² = 12.5 mm³. Distractor A (10.5) results from an arithmetic error, C (25.0) confuses the length with the volume, and D (50.0) results fro
