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