The student wants to present the study to an audience already familiar with environmental DNA. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A
Sara Oyler-McCance’s researchers analyzed eDNA in water samples from the Florida Everglades for evidence of invasive constrictor snakes, which are difficult to observe.
B
An analysis of eDNA can detect the presence of invasive species that are difficult to observe, such as constrictor snakes.
C
Researchers found Burmese python eDNA, or environmental DNA, in water samples; eDNA is the DNA in released cellular materials, such as shed skin cells.
D
Sara Oyler-McCance’s researchers analyzed environmental DNA (eDNA)—that is, DNA from cellular materials released by organisms—in water samples from the Florida Everglades.
Explanation
Correct answer: A.
Choice A is the best answer. This choice presents the study in a way that assumes the audience is already familiar with eDNA.
Why the other choices are wrong
Choice B
Choice B is incorrect. This choice doesn’t present the study. It only states a general fact about eDNA analysis.
Choice C
Choice C is incorrect. This choice isn’t suited for an audience already familiar with eDNA. A familiar audience wouldn’t need to have the term defined or explained.
Choice D
Choice D is incorrect. This choice isn’t suited for an audience already familiar with eDNA. A familiar audience wouldn’t need to have the term defined or explained. It also doesn’t present the study.
