Cells AStudent placed a freshwater aquarium containing aquatic plants in a laboratory window and monitored oxygen levels in the water from early morning to noon. They observed a steady rise in dissolved oxygen levels from morning until noon. What is the best explanation for this observation?

a. The sunlight increased the temperature resulting in more oxygen exchange between the air and water.

b. The plants began photosynthesis resulting in less oxygen use by the plants.

c. The plants began photosynthesis resulting in oxygen release from the plants.

d. There were fish in the water that released oxygen from their gills.

Cells BA scientist is using transparent (light-penetrating) bottles are opaque

(light-blocking) bottle to measure the productivity of algae pond water. Equal amounts of pond water are put in both bottles, which are then capped. They are then placed in the pond at a depth of 0.5 meters at 6:00am. The pond water was collected at 10:00am the same day. Which of the following results is the scientist likely to observe?

a. The transparent bottle has a higher concentration of dissolved oxygen than the opaque bottle.

b. The transparent bottle has a lower concentration of dissolved oxygen than the opaque bottle.

c. The total phosphorus concentration will be greater than the transparent bottle.

d. The total phosphorus concentration will be greater in the opaque bottle.
