1. read the article then explain how rapid reproduction in bacteria causes them to evolve quickly.
2. list 2 reasons we should be concerned about antibiotic resistance.
3. finally, of the possible causes provided (in class or from the article) share the one you think is most at fault for our superbug (bacteria resistance) problem.

Answer No 1:

The ability of bacteria to reproduce in a rapid manner allows it to evolve quickly. As the rate of reproduction is more, the rate of mutations to occur also becomes more. By these mutations, some bacteria might become resistant to antibiotics.

Answer No 2:

Two reasons we should be concerned about antibiotic resistance are:

1: Harmful strains of bacteria which are mutant against the antibiotic will cause harmful diseases in humans as well as animals. As they would become resistant to antibiotics we won't be able to kill them.

2: The harmful strains of bacteria can become so strong in number that they might outnumber the useful micro flora that we possess.

Answer No 3:

The overuse of antibiotics led to the bacteria developing mutations at such a faster rate. The use of antibiotics should have been limited to only under serious circumstances.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
