|---|---|---|---|---|---|
| show | 1a. An organism that causes disease.
🗑
|
||||
| 1b. Saprophyte | show 🗑
|
||||
| 1c. Parasite | show 🗑
|
||||
| show | 1d. An organism that requires oxygen.
🗑
|
||||
| show | 1e. An organism that does not require oxygen.
🗑
|
||||
| 1f. Steady state | show 🗑
|
||||
| show | 1g. Population growth that is unhindered because of the abundance of resources for an ever-increasing population.
🗑
|
||||
| 1h. Logistic growth | show 🗑
|
||||
| show | 1i. A temporary union of two organisms for the purpose of deoxyribonucleic acid (DNA) transfer.
🗑
|
||||
| show | 1j. A small, circular section of extra DNA that confers one or more traits to a bacterium and can be reproduced separately from the main bacterial genetic code.
🗑
|
||||
| show | 1k. The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell.
🗑
|
||||
| show | 1l. The process in which infection by a virus results in DNA being transferred from one bacterium to another.
🗑
|
||||
| show | 1m. The DNA and other essential parts of a bacterium coated with several hard layers.
🗑
|
||||
| show | 1n. Organisms from the same species that have markedly different traits.
🗑
|
||||
| show | a.Plasma membrane b.Flagellum c.Capsule d.Deoxyribonucleic acid e.Cytoplasm f.Cell wall g.Fimbria h.Ribosome
🗑
|
||||
| 3. Describe the functions of each of the components labeled in problem #2. | show 🗑
|
||||
| 3. (continued) | show 🗑
|
||||
| show | Feeding on dead matter.
🗑
|
||||
| show | Heterotrophic because it feeds on a living host.
🗑
|
||||
| 6. List the basic steps in asexual reproduction (more specifically binary fission) among bacteria. | show 🗑
|
||||
| show | E. When the cell wall and plasma membrane growth is complete, two bacteria (a parent and an offspring) exist where there was once just one. As long as no mutation took place, the two bacteria are identical.
🗑
|
||||
| show | Several of the bacteria formed endospores, which, although the bacteria died, they reformed because the endospore survived.
🗑
|
||||
| show | Exponential growth.
🗑
|
||||
| 9. A population of bacteria experiences logistic growth. What can you say about the resources of their environment? | show 🗑
|
||||
| show | Because DNA can be transfered, resulting in genetic information being donated that could be useful to the recipient, therefore possibly expanding the recipient's life.
🗑
|
||||
| show | Coccus (spherical), bacillus (rod-shaped), and spirillem (helical).
🗑
|
||||
| 12. A bacterium is heterotrophic and Gram-negative. To what phylum and class does it belong? | show 🗑
|
||||
| show | Phylum Firmicutes and class Thallobacteria.
🗑
|
||||
| show | Phylum Tenericutes and class Mollicutes.
🗑
|
||||
| 15. A bacterium lives in boiling-hot water. To what phylum and class does it most likely belong? | show 🗑
|
||||
| 16. In the six-kingdom classification system, what replaces kingdom Monera? | show 🗑
|
||||
| show | Moisture, moderate temperature, nutrition, darkness and oxygen.
🗑
|
||||
| show | Exposing the food to extreme heat or radiation, freezing the food, and dehydration.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
