Answer 1

The gas bubbles produced in the investigation are most likely to contain molecules of oxygen.

When aquatic plants undergo photosynthesis, they take in carbon dioxide and water and, in the presence of light, produce glucose and release oxygen as a byproduct. Therefore, if the plant is exposed to a light source, the gas bubbles observed would primarily be oxygen.
