Explain why respiration moves the marker to the left, towards the seed chamber.
In a two-hour run, the marker travels 40 mm through a capillary of internal radius 0.60 mm. Calculate the oxygen uptake rate in mm³ h⁻¹ to two decimal places. Use V = πr2l with π = 3.14.
The sealed chamber contains respiring seeds above a carbon-dioxide absorbent. Temperature and atmospheric pressure remain constant. Which movement is expected for the liquid marker? A. Away from the chamber because oxygen is released B. No movement because…
Two sealed seed chambers have identical starting conditions. The seeds consume carbohydrate, so oxygen uptake approximately matches carbon-dioxide release. Which marker movements are expected at constant temperature and pressure? A. Both: right B. P:…
This sealed apparatus is kept at constant temperature. Initially the liquid levels in the two arms were equal. The diagram shows the later result. Potassium hydroxide absorbs carbon dioxide. What does the result indicate? A. The living seeds produce more…
