loihi shrimp—originally thought to exist only around an undersea volcano near 6 hawaii, survive by using tiny, shear - like claws to harvest rapidly growing bacterial filaments covering rocks near nw rota - 1’s hydrothermal vents. the loihi shrimp spend most of their time grazing on the bacteria and evading another, previously unknown, species of shrimp. shrimp of that species also graze on bacterial filaments as juveniles, 7 resulting from their ability to cope with the noxious environment around the volcano. they feed on the loihi shrimp and other organisms that are overcome by the toxic plumes of volcanic gas and ash.

Explanation:

Question 6

The original sentence has a dash after "near" to introduce additional information, so we need to use a dash to set off the location "Hawaii" as part of the parenthetical information. Option C uses a dash, which is correct. Option A has a period which is wrong, Option B has a semicolon which is incorrect for this context, and Option D has no punctuation to set off the parenthetical.

The next sentence talks about the other shrimp species feeding on Loihi shrimp and other organisms. We need a sentence that sets up this predatory behavior. Option D says that as adults, their claws are large enough for the shrimp to be predators, which leads into the next sentence about them feeding on other organisms. Option A doesn't set up the next sentence, Option B is about scientific understanding which is off - topic, and Option C is about the ecosystem which doesn't lead to the predatory behavior.

Answer:

C) Hawaii—
