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

A recent decline in the population of loggerhead turtles off the coast of Argentina made researchers curious. They hypothesized that this decline led to a decline in the overall algae and marine plant life in the region. Loggerhead turtles are not known to eat algae or marine plants, but they do consume conchs and crabs whose diet primarily consists of marine plant life and algae. Which finding, if true, would most directly support the researcher’s hypothesis? Overall decreases in the traditional food sources of the loggerhead turtle other than conchs could account for the decrease in the loggerhead turtle’s numbers. eliminateConchs and crabs have increased in population in the region while the population of loggerhead turtles has declined. eliminateConchs and crabs have been consuming too much of the region’s algae and marine plant population prior to the decline in loggerhead turtle population. eliminateThe overall population of algae and marine plants tends to be larger in regions where there are more loggerhead turtles and crabs. eliminate

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.
