Average Number and Duration of Inactive and Active Periods for American and Chinese AlligatorsFeature American alligators Chinese alligatorsInactive periods 12 10average duration of inactive periods 2.5 days 5 daysActive periods11 9average duration of active periods 1 day .75 daysAlligators are known to brumate in winter months, a process very similar to hibernation in some mammalian species. During this time, metabolic processes slow, and the animals are largely inactive, though on warmer days they will become active again, often emerging from the water to sun themselves on shore. Researchers studying two different species of alligator—the American alligator and the Chinese alligator—hypothesized that because temperatures are generally colder in the regions where Chinese alligators are found compared to temperatures of the habitats of their American counterparts during the brumation period, Chinese alligators would likely have, on average, longer durations of inactivity and shorter durations of activity than American alligators. Which choice most effectively uses data from the table to support the researchers' hypothesis?The American alligators' active periods lasted for less than a day, while the Chinese alligators' active periods lasted for many days.eliminateThe American alligators and the Chinese alligators both maintained inactive periods for several consecutive days per period, on average.eliminateThe American alligators had more inactive periods than active periods, but their active episodes were much shorter than their inactive periods. eliminateThe American alligators had shorter durations of inactivity and longer durations of activity than the Chinese alligators did.

Number and Duration of the Heat and Anestrous Periods of African and Asian Lions in a YearFeature African Lions Asian Lionsheat periods 9 7duration of heat periods 3.5 days 12.4 daysanestrous periods 10 8duration of anestrous periods 1.2 months 1.1 monthsAfrican and Asian lions, though closely related, exhibit some differences in their reproductive (heat periods) and resting behaviors (anestrous periods). African lions typically have slightly more heat periods than Asian lions, but the duration of each cycle tends to be shorter compared to Asian lions. A researcher hypothesized that because African lions are more polyamorous than Asian lions (that is, more likely to take many partners within their prides), they are likely to exhibit an increased number of reproductive periods, but require longer rest periods in-between to account for the increased energy exerted during the periods of heat.Which choice best describes data from the table that support the researcher’s hypothesis?The heat periods of African lions last an average of 3.5 days while the heat periods of Asian lions last an average of 12.4 days.eliminateAfrican lions have an average of 10 anestrous periods a year while Asian lions have an average of 8 anestrous periods a year.eliminateAfrican lions have an average of 2 more anestrous periods a year than Asian lions do, and their heat periods last an average of 8.9 days longer than those of Asian lions.eliminateAsian lions have an average of 2 fewer heat periods a year than African lions do, and their anestrous periods last an average of 0.1 months less than those of African lions.

The spectacled caiman (Caiman crocodilus), a species of crocodile native to Central and South America, became an invasive species in the Everglades in the 1970s, when caimans were imported to Florida as pets and for the crocodilian farm industries. Caimans prey upon birds, small mammals, fish, and other reptiles, just like native alligators and crocodiles. Caimans pose a threat to native wildlife because -------Which choice most logically completes the text?they appear similar to native alligators and crocodiles.eliminatethey propagate with native species of alligators and crocodiles.eliminatethey compete with native wildlife for food and other resources.eliminatethey are likely to kill native alligators and crocodiles.

In a marsh ecosystem, alligators feed on blue crabs. Blue crabs feed on saltmeadow grass, shrimp, and detritus. What would most likely happen to the food web if there were a sudden decrease in the number of blue crabs?Group of answer choicesThe populations of shrimp and saltmeadow grass would remain the same while the population of alligators would increase.The population of shrimp and saltmeadow grass would decrease while the population of alligators would increase.The populations of shrimp and saltmeadow grass would increase while the population of alligators would decrease.None of the above
