Which option orders the events in chronologically from earliest to latest single cell organisms increase in atmospheric methane concentrations photosynthetic bacteria releases oxygen into the sea oxygen concentrates increasing the atmosphere many new animal species evolve single-celled organisms increase atmospheric methane concentrate oxygen concentrates increase in the atmosphere photosynthesizing bacteria releases oxygen into the sea many new animals species of evolve many new animal species evolve single-celled organisms increase photosynthetic bacteria release oxygen into the sea oxygen concentration increase the atmosphere

Answer 1

To order the events chronologically from earliest to latest, we can summarize the process as follows:

1. Single-celled organisms increase (These are some of the earliest forms of life.)
2. Photosynthetic bacteria release oxygen into the sea (Bacteria begin the process of photosynthesis.)
3. Oxygen concentration increases in the sea (As more oxygen is produced, it begins to dissolve in the oceans.)
4. Oxygen concentrates in the atmosphere (Over time, as more oxygen is produced, it starts to accumulate in the atmosphere.)
5. Many new animal species evolve (The increase in atmospheric oxygen leads to the evolution of more complex life forms, including animals.)

So, the chronological order should look like this:

1. Single-celled organisms increase
2. Photosynthetic bacteria release oxygen into the sea
3. Oxygen concentration increases in the sea
4. Oxygen concentrates in the atmosphere
5. Many new animal species evolve

The options you provided seem to differ in phrasing, but the correct sequence should follow this logical progression.
