During the 1980s, lobster fishers put together artificial reefs in the western Atlantic Ocean in order to attract Caribbean spiny lobsters, which are among the most popular lobsters among seafood restaurants. Soon after, dozens of piles of clam shells were discovered just outside of the reefs. Marine biologist Dr. Nicholas Higgs conducted a study to test his hypothesis that sea-grass-dwelling lucinid clams make up a portion of the spiny lobsters’ diets, believing that it was the lobsters who were depositing the shells close to the artificial reefs.Which finding, if true, would most directly undermine Higgs’ hypothesis?The shells of lucinid clams are hard to open and as a result, Caribbean spiny lobsters only eat the clams when there are shortages of easier to obtain prey.eliminateThe piles of shells were covered by a layer of silt, which indicates that they were already there before the artificial reefs were constructed.eliminateThe population of Caribbean spiny lobsters was found to increase wherever the population of the lucinid clams increased.eliminateThe number of shells was found to increase in areas frequented by lobster fishermen.

Marine Biologist Laura Evans, Botanist Henry Gilbert, and their team delved into the domestication of sea creatures in Pacific Ocean reefs during the Neolithic Era (approximately 6000 to 3000 BCE). By analyzing the chemical makeup of the bones of various fish, turtles, and crabs from this era, the team inferred that natural sea vegetation made up the majority of the diet for fish and turtles, while crabs primarily subsisted on seaweed, a crop cultivated by humans. The team deduced that crabs were likely raised closer to human settlements, whereas fish and turtles were permitted to traverse farther away.11 Mark For Review11Which finding, if true, would most strongly support the team’s conclusion?A) Analysis of the animal bones unveiled that the crabs' diet also consisted of algae, which humans broadly cultivated in Pacific Ocean reefs during the Neolithic Era.B) The diets of fish, turtles, and crabs were found to vary based on what the cultivators in each Neolithic settlement could grow.C) Crabs' diets generally demand larger quantities of food and a broader range of nutrients than do fish and turtles' diets.D) Further examination of fish and turtle bones showed that their diets included small portions of seaweed as well.Select Answer(s)ABCD

While researching a topic, a student has taken the following notes:Instances of marine animals washing ashore have been well-studied in species like dolphins and whales, for which such occurrences are fairly commonplace, but not in octopuses, which are far less likely to be found on beaches.Brett Stones and a team of scientists observed dozens of curled octopuses washed up on shore in Wales.Stones and his team observed each octopus using their tentacles to “walk” across the shore.The octopuses were not found to have any injuries or signs of harm.Many of the same species of octopus were later found to be dead in the ocean some distance away from the shoreline.Though the team is investigating the cause of this behavior, no explanation has yet been found.The student wants to emphasize the mysterious nature of the phenomenon. Which choice most effectively uses relevant information from the notes to accomplish the goal?After they discovered many octopuses “walking” on the shore, Stones and his team discovered more of the same octopus species in the ocean.eliminateWe now know that dolphins and whales are not the only marine animals known to wash ashore; octopuses have been found washed ashore as well.eliminateStones and his team made observations regarding dozens of octopuses, and how they used their tentacles to move around the Welsh shore.eliminateScientists were unable to determine the reason dozens of octopuses were found "walking" on a shore in Wales, or what caused the deaths of many of the same species of octopus in the water off the shoreline.
