Please use the following information to answer the question(s)below.
A hypothetical bacterium swims among human intestinal contents until it finds a suitable location on the intestinal lining.It adheres to the intestinal lining using a feature that also protects it from bacteriophages and dehydration.Fecal matter from a human in whose intestine this bacterium lives can spread the bacterium,even after being mixed with water and boiled.The bacterium is not susceptible to the penicillin family of antibiotics.It contains no plasmids and relatively little peptidoglycan.
-This bacterium's ability to survive in a human who is taking penicillin pills may be due to the presence of which of the following?
1)penicillin-resistance genes
2)a gram-positive cell wall
3)a gram-negative cell wall
4)an endospore
A)1 or 4
B)1 or 3
C)2 or 4
D)3 or 4

The fact that the bacterium is not susceptible to the penicillin family of antibiotics indicates that it may have some form of resistance mechanism. However, the bacterium does not contain any plasmids, which are often responsible for antibiotic resistance genes. Therefore, it is possible that the bacterium's ability to survive in a human taking penicillin is due to its cell wall structure or the presence of an endospore. The bacterium is described as having relatively little peptidoglycan, which is a characteristic of gram-negative cell walls. Additionally, the feature that the bacterium uses to adhere to the intestinal lining and protect itself from dehydration and bacteriophages could potentially be an endospore. Therefore, the best choice is D (3 or 4).
