Question

Which of the following conclusions can we draw from Lenski's long-term laboratory experiments with E. coli?

1) E. coli can adapt and evolve over time.
2) E. coli can develop new genetic traits.
3) E. coli can survive in different environments.
4) E. coli can reproduce rapidly.
5) None of the above

Answer 1

The conclusions we can draw from Lenski's long-term laboratory experiments with E. coli are that E. coli can adapt and evolve over time, develop new genetic traits, survive in different environments, and reproduce rapidly.

Step-by-step explanation:

From Lenski's long-term laboratory experiments with E. coli, we can draw the conclusion that:

1. E. coli can adapt and evolve over time. Lenski's experiments have shown that E. coli populations can undergo genetic changes and evolve new traits in response to their environment.
2. E. coli can develop new genetic traits. Lenski's experiments have observed the emergence of new traits in E. coli populations, such as the ability to utilize a new food source.
3. E. coli can survive in different environments. Lenski's experiments have demonstrated that E. coli can survive and thrive in diverse laboratory environments with varying conditions.
4. E. coli can reproduce rapidly. Lenski's experiments have shown that E. coli populations can reproduce quickly, allowing for rapid evolution and adaptation.

Therefore, the correct conclusion from Lenski's experiments is that E. coli can adapt and evolve over time, develop new genetic traits, survive in different environments, and reproduce rapidly.
