Answer 1

To order the events chronologically, we should consider the evolutionary timeline:

1. Photosynthesizing bacteria release oxygen into the sea (these organisms were some of the first to photosynthesize and produce oxygen).
2. Oxygen concentrations increase in the atmosphere (as more oxygen was produced by photosynthetic organisms).
3. Single-celled organisms increase atmospheric methane concentrations (methane was also a significant component of the atmosphere in certain periods).
4. Many new animal species evolve (the rise of oxygen set the stage for more complex life forms to evolve).

Thus, the correct chronological order of the events is:

Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Single-celled organisms increase atmospheric methane concentrations. Many new animal species evolve.

Since this specific order isn't listed, based on the events mentioned, the closest correct sequence from your options is:

Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.

This assumes that single-celled organisms can indeed contribute to methane concentrations early in the timeline, but the absolute critical steps involve oxygen production leading to diversity in animal life.

If you strictly follow the oxygen sequence, focus should be on the release of oxygen leading to the later sequences. So the ideal choice should include that comparing to the proper sequence outlined above.

Answer 3

The correct chronological order of the events from earliest to latest is:

Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.

However, since this specific sequence isn't presented in the options you provided, the option that closely follows this order is:

Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.

If this option is among the choices, that would be the correct selection. If none of the given options match, please share them, and I can help further.
