Question

the model below shows the initial result of treating a population of bacteria with antibiotics. the red bacteria represent mutated bacteria that are resistant to antibiotics. which of the following describes what would most likely happen to the bacteria population next? no bacteria will be left after the red bacteria mutate and are killed by the antibiotic. the red bacteria will remain but will not be able to reproduce due to their mutation. the red bacteria will reproduce, creating an equal number of red and blue offspring. the red bacteria will reproduce and pass on their mutation to their offspring.

Explanation:

In the context of natural selection and bacterial resistance, the red (resistant) bacteria survive antibiotic treatment. Bacteria reproduce asexually (e.g., binary fission). The mutation that confers antibiotic resistance is in their genetic material (DNA). When they reproduce, they pass this genetic material (with the resistance - conferring mutation) to their offspring.

• The first option is incorrect because red bacteria are resistant (not killed by the antibiotic).
• The second option is wrong as bacterial mutations (in this case, for resistance) do not typically make them unable to reproduce.
• The third option is incorrect because the blue bacteria (non - resistant) are killed by the antibiotic, so there are no blue bacteria to contribute to an "equal number of red and blue offspring."

So, the most likely outcome is that the red bacteria reproduce and pass on their mutation (antibiotic resistance) to their offspring.

Answer:

The red bacteria will reproduce and pass on their mutation to their offspring.
