Answer 1

To order the events chronologically from earliest to latest, we need to consider the biological processes involved:

1. Single-celled organisms increase atmospheric methane concentrations: This likely occurred early as these organisms were among the first life forms on Earth.
2. Photosynthesizing bacteria release oxygen into the sea: Over time, photosynthetic organisms began to produce oxygen.
3. Oxygen concentrations increase in the atmosphere: As photosynthetic bacteria and later plants evolved, oxygen levels began to rise in the atmosphere.
4. Many new animal species evolve: The increase of oxygen in the atmosphere allowed for the evolution of more complex life forms, including various animal species.

So, the correct chronological 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.

Therefore, the correct option 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.
