quester [9]
No, this is false!

Renewable resources can be syntesized by humans, or not: some of them can, and some can't. This is not what makes them renewable, instead it's the fact that they will still be present in the nature after usage - they will be replaced (the sun will still shine tomorrow even if we harvest its power).

Papessa [141]

Answer:

The trait must make the individual more fit to survive. True

Explanation:

Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.

The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.
