Question
In her book How We Age, geneticist Coleen Murphy explores how is aging is impacted by trans-generational inheritance—the idea that environmental phenomena such as starvation and trauma in one generation can have biological effects on many subsequent generations. In her research, Murphy found that when roundworms were affected by the bacterium Pseudomonas, five generations of offspring avoided food that was contaminated with the bacterium, suggesting that -------Which choice most logically completes the text?Pseudomonas still presented a real and active danger for roundworms.eliminateroundworms are unique in their ability to "remember" the dangers and traumas faced by previous generations. eliminatesubsequent generations of roundworms "remembered" the infection that occurred generations earlier.eliminateroundworms were generally unaffected by the traumas and dangers faced by previous generations.
Solution
The choice that most logically completes the text is "subsequent generations of roundworms "remembered" the infection that occurred generations earlier." This is because the text discusses the concept of trans-generational inheritance, where the experiences of one generation can impact subsequent generations. The avoidance of food contaminated with Pseudomonas by five generations of offspring suggests that these roundworms somehow "remembered" the infection from previous generations.
