Question
A partial population of bacteria is shown. Three traits in the population are indicated in the image:
• an outer slime layer that prevents molecules from crossing the cell membrane of the bacteria
• a flagellum that allows the bacteria to swim toward nutrients
• an efflux pump that allows the bacteria to pump out foreign chemicals
When exposed to an antibiotic that kills bacteria by entering and accumulating within the bacterial cells, which individual organisms will MOST LIKELY survive and pass on their traits?
Select EIGHT correct answers.
• an outer slime layer that prevents molecules from crossing the cell membrane of the bacteria
• a flagellum that allows the bacteria to swim toward nutrients
• an efflux pump that allows the bacteria to pump out foreign chemicals

Select EIGHT correct answers.
Answers
GPT 3.5
The individuals that are most likely to survive and pass on their traits are those that possess the following characteristics:
1. A lack of an outer slime layer that prevents molecules from crossing the cell membrane. This allows the antibiotic to enter the bacterial cell.
2. A flagellum that allows the bacteria to swim toward nutrients. This trait aids in finding food sources.
3. An efflux pump that allows the bacteria to pump out foreign chemicals. This trait helps remove the antibiotic from the bacterial cell.
Therefore, the correct answers are:
- Organisms that lack an outer slime layer
- Organisms that possess a flagellum
- Organisms that possess an efflux pump
- Organisms that lack an outer slime layer and possess a flagellum
- Organisms that lack an outer slime layer and possess an efflux pump
- Organisms that possess a flagellum and possess an efflux pump
- Organisms that lack an outer slime layer, possess a flagellum, and possess an efflux pump
- Organisms that possess a flagellum and lack an outer slime layer (order of traits does not matter)
1. A lack of an outer slime layer that prevents molecules from crossing the cell membrane. This allows the antibiotic to enter the bacterial cell.
2. A flagellum that allows the bacteria to swim toward nutrients. This trait aids in finding food sources.
3. An efflux pump that allows the bacteria to pump out foreign chemicals. This trait helps remove the antibiotic from the bacterial cell.
Therefore, the correct answers are:
- Organisms that lack an outer slime layer
- Organisms that possess a flagellum
- Organisms that possess an efflux pump
- Organisms that lack an outer slime layer and possess a flagellum
- Organisms that lack an outer slime layer and possess an efflux pump
- Organisms that possess a flagellum and possess an efflux pump
- Organisms that lack an outer slime layer, possess a flagellum, and possess an efflux pump
- Organisms that possess a flagellum and lack an outer slime layer (order of traits does not matter)
