Question

the bacteria with 3 pores decreased in number after exposure to antibiotics because they did not evolve. the 5 - pore bacteria increased in number because they were strengthened by the antibiotic. this variation of bacteria was not adaptive. part b the highlighted portion(s) of this claim is (are) incorrect because: select all that apply. evolution is a process where organisms adapt to environmental conditions but there were no environmental conditions to adapt to. the 5 - pore bacteria decreased in number of individuals but not in proportion to other variations. the 5 - pore bacteria increased in proportion to other variations. evolution does not happen in one variation, it happens in a population of organisms.

Explanation:

Evolution is a population - level process where organisms adapt to environmental changes over time. Bacteria with 3 pores decreased due to lack of adaptation to antibiotics, which is an environmental stressor, and it is an example of evolution at the population level. The claim that 5 - pore bacteria increased because they were strengthened by the antibiotic is incorrect as bacteria don't get strengthened by antibiotics in that way; rather, resistant variants survive and reproduce more. Also, evolution doesn't happen in a single variant but in a population.

Answer:

Evolution is a process where organisms adapt to environmental conditions but there were no environmental conditions to adapt to; Evolution does not happen in one variation, it happens in a population of organisms.
