Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 3 mm from the initial level in 20 min, and when measuring cellular respiration it took 15 minutes for the water level to move down 1 mm.

The rate of photosynthesis is 13 mm/hr

Explanation:

The rate of net photosynthesis is given by;

rate of net photosynthesis = 3 mm / 20 min = 1.5 mm/ 10 min

The rate of  cellular respiration is given by;

rate of cellular respiration = 1 mm / 15 min = 0.667 mm / 10 min

The rate of photosynthesis is given by;

rate of photosynthesis = rate of net photosynthesis + rate of cellular respiration

rate of photosynthesis = 1.5 mm/ 10 min + 0.667 mm / 10 min

rate of photosynthesis =2.167 mm/ 10 min

Therefore, the rate of photosynthesis is 13 mm/hr

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
