Prokaryotes & Viruses

All the following are reasons why the development of antibiotic resistance in bacteria is considered an example of evolution, except:

Bacteria that are susceptible to the antibiotic are more fit and will be able to reproduce more.

Many prokaryotes demonstrate taxis, mainly through the use of flagella. How do these bacteria utilize phototaxis?

Bacteria utilize phototaxis to move towards or away from light, often for photosynthesis.

Prokaryotes consist of both bacteria and archaea. Which of the following statements best characterize these types of organisms?

Both bacteria and archaea meet all the characteristics for life.

Prokaryotes have a small amount of DNA when compared to eukaryotic cells. How does this fact often lead to mutualism between bacterial cells?

Each species of bacteria can produce particular proteins that can be absorbed and benefit all bacteria living within the same area.

Why is the development of Germ Theory considered an example of scientific progress?

Germ Theory led to further discoveries in infectious diseases and immunology, but it could not have happened without the development of the microscope.

Bacteria and humans can have different types of relationships based upon who benefits and who does not. Which of the following describes a mutualistic benefit between bacteria and humans?

One type of bacteria enables further digestion of foods within the human intestine, while using this food as its own food source.

Which of the statements correctly describes prokaryotic cells?

Prokaryotic cells share similarities with eukaryotic cells, by containing ribosomes and DNA within a cell membrane.

Many archaea are considered to be extremophiles. What characteristic do these organisms have that results in this designation?

These organisms have been found in extreme temperatures, pH, and high salt.

Bacterial cells have a carbohydrate cell wall and many also have a capsule. How do these structures function in bacteria?

These two structures both function in protection for the bacterial cell.

Which of the following correctly states the relationship(s) between bacteria and humans?

Some bacteria act as catalysts in the chemical reactions of human cells. Some bacteria are harmful to humans. Some bacteria assist humans in digesting food. All of the above
