Q1. Is bacterial antibiotic resistance is a good model to study
evolution? How Darwinism is different from bacterial antibiotic
resistance?
Yes, bacterial antibiotic resistance is an excellent model to study evolution; this is because,
via natural selection, antibiotics resistance becomes a consequence of evolution (Bitesize 2019).
The context of whether antibiotics resistance can be used in the study of evolution can clearly be
expressed through the process involved in developing antibiotic resistance in bacteria. These
include the random DNA mutations which occur in individual bacteria cells. With these mutations,
bacterial cells develop a protective system against antibiotics hence becoming resistant. These
mutations produce new characteristics in which evolution entails the change in characteristics of a
species. Darwinism is different from bacterial antibiotic resistance because Darwinism champions
natural selection as an influencer in evolution. Natural selection implies the difference in an
environmental adaptation by organisms depending on how better they are than others. The
difference in adaptability between organisms is caused by mutation.
Q2. A friend states, “Exposing bacteria to antibiotics causes the
cells to mutate to become antibiotic resistant.” Explain to your friend
why he is incorrect and provide the correct explanation.
My friend was right; this is because when bacteria encounter an antibiotic, they are
malfunctioned and sometimes if the antibiotic is strong enough, it kills the bacteria. Antibiotics
suspend the growth of the bacteria. If the bacteria are exposed more, they tend to develop
abilities to withstand antibiotics effects. The development of these abilities is through the process
referred to as mutation is the process by which organisms develo...
