| 2. |
Bacteria lack nuclei and therefore also lack genetic material.
|
|
| 3. |
Bacterial cells have membrane-bound organelles and chromosomes.
|
|
| 4. |
Bacterial cells are usually much larger than eukaryotic cells.
|
|
| 5. |

|
|
| 6. |
Some bacteria cannot survive in the presence of oxygen.
|
|
| 7. |
When bacteria undergo nonreproductive genetic recombination, their bacterial chromosome is altered.
|
|
| 8. |
Certain antibiotics have become ineffective against certain strains of bacteria. These bacteria have developed a resistance, which may be passed on from one generation of bacteria to the next.
|
|
| 9. |
The photoautotrophic bacteria are the only bacteria that are indirectly beneficial to humans.
