Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
All water has been recycled by the rain many times. True
Answer:
The correct answer is "natural selection in Staphylococcus aureus populations".
Explanation:
Natural selection is a process at which populations of organisms develop advantageous traits under the premise of survival of the fittest. In this case, the continuous exposure to penicillin and other antibiotics since 1940s have a natural selection effect in Staphylococcus aureus populations, allowing an increase in antibiotic-resistant alleles in the bacteria, which acts as an advantageous trait for them. Antibiotic resistance is a serious medical concern that has been addressed by a culture of responsible use of antibiotics and development of novel treatments for infections.

The advantage of being double stranded in DNA is that double strands makes it much more stable. <span>Having two alleles for one gene gives variation. </span><span>Double Stranded DNA can tolerate many risk factors from the homeostasis' processes that is keeping the cells alive. </span><span>Double-stranded DNA ensures that the actual genetic information is less likely to react, and it can be opened in the case of replication and transcription. </span> <span>Another advantage of double strand DNA is the ability of the cell to create a new portion of DNA in case of DNA damage, by using the non-damaged strand.</span>
