The diagram below represents levels of organization in living

things.

Muscle cells in athletes often have more mitochondria than muscle cells in non-athletes.

Based on this observation, it can be inferred that the muscle cells in athletes

1. have a smaller demand for

cell proteins than the muscle

cells of non-athletes

2. reproduce less frequently than the muscle cells of non-athletes

3. have nuclei containing more DNA than nuclei in the muscle cells of non-athletes

4. have a greater demand for energy than the muscle cells of non-athletes
