Question

While researching a topic, a student has taken the following notes:

Mexican tetras are a fish species with two distinct populations.
Surface-dwelling tetras live on the surface and are able to see.
Cave-dwelling tetras live in total darkness and have lost the ability to see.
Cave-dwelling tetras have asymmetrical skulls with more sensory receptors on one side than the other.
These receptors help cave-dwelling tetras navigate in darkness.

The student wants to emphasize a difference between surface-dwelling and cave-dwelling tetras. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Accepted Answer

Choice D is the best answer. The sentence emphasizes a difference between surface-dwelling and cave-dwelling tetras, noting that while surface-dwelling tetras can see, cave-dwelling tetras can&rsquo;t. Choice A is incorrect. While the sentence notes that surface-dwelling and cave-dwelling tetras are different, it doesn&rsquo;t emphasize any difference between the two populations of tetras. Choice B is incorrect because the sentence explains that cave-dwelling tetras use sensory receptors on their skulls to navigate; it doesn&rsquo;t emphasize a difference between surface-dwelling and cave-dwelling tetras. Choice C is incorrect. While the sentence notes that there are two different populations of Mexican tetras, it doesn&rsquo;t emphasize any difference between the two populations.
