Answer: D. The genes for antibiotic resistance help the transformed bacteria survive in their environment.
Explanation:
First and foremost, we should note that plasmids used in the delivery of DNA typically consists of genes which helps in antibiotic resistance.
Based on the question given, we should note that the genes for antibiotic resistance help the transformed bacteria survive in their environment. This is because cells that have been treated with plasmid are able to survive and grow compared to those that have not been treated with plasmid which are eventually killed by the antibiotic.
The right answer is C.
Classically positive interactions or facilitators between species are divided into two broad categories:
- those where the two partners involved benefit from each other: the mutualisms (symbolized by + / +)
- those where one of the two partners makes a profit or an advantage while the other gets nothing from it without being affected negatively: it is the commensalism symbolized by + / 0.
It may be that bacterial commensalism has an interest in its host (the animal) in the sense that it protects against parasites, or on the contrary, it favors their appearance.
