Question

the diagram below shows an investigation performed over a period of 6 hours. an aquatic plant is placed in water and exposed to a light source. the gas bubbles produced in this investigation most likely contained molecules of
(1 point)
uric acid
methane
oxygen
co₂

Explanation:

Plants perform photosynthesis. The general equation for photosynthesis is \(6CO_2 + 6H_2O+light
ightarrow C_6H_{12}O_6+6O_2\). In this experiment, an aquatic plant is exposed to light. During photosynthesis, oxygen (\(O_2\)) is produced as a by - product. Uric acid is a waste product in some animals' metabolism. Methane (\(CH_4\)) is not a product of plant photosynthesis in this context. Carbon dioxide (\(CO_2\)) is a reactant in photosynthesis, not the gas being produced (the gas produced is the result of the reaction, and \(O_2\) is the product gas in photosynthesis).

Answer:

oxygen
