a. the production of bubbles by the plant when it is in darkness

Explanation:

The indirect observation that will show that the gas produced in this experiment is oxygen is by observing the bubbles on the surface of water in darkness.

Oxygen gas is a by product of photosynthesis. Photosynthesis occurs in the dark and when there is light.

If we observed the bubbles over water, it shows that oxygen gas is given off and the water plant is photosynthesizing. This is a good way to observe the oxygen gas indirectly.

How does artificial selection provide evidence for evolution by natural selection
Cloud [144]

Answer:

Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.

Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.

The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.
