ABC Question 8Which of the following is a nonliving factor that a penguin could interact with in an Arctic environment?A a ray of sunlight that makes the penguin blend into the surface of the waterB a shark that sees the penguin and swims toward it under the waterC another penguin that could be a potential mate for reproductionD a polar bear that follows the penguin in hopes of catching and eating i

A seal and a shark eat the same type of fish.Which ecological interaction describes the relationship between the seal and the shark?

21In the harsh Antarctic winter, the emperor penguin, which is the only penguin species that breeds during this period, endures freezing temperatures and blizzards to reproduce. This survival strategy, unique to the emperor penguin, has intrigued wildlife ______ asserts it "expanded the range of possibilities for penguin survival strategies in extreme conditions."21 Mark For Review21Which choice completes the text so that it conforms to the conventions of Standard English?A) biologist, Gerald Kooyman, whoB) biologist Gerald Kooyman, whoC) biologist Gerald Kooyman who,D) biologist; Gerald Kooyman, who

A comparison of the energy expenditures in their native habitats (kcal/kg/day) for a penguinand for a python (assuming they are of equal size) would show that:A. the energy expenditure of the penguin is greater than that for the python.B. the energy expenditure of the penguin is less than that for the python.C. the energy expenditure of the penguin is equal to that for the python.D. the comparison is meaningless because they are not the same type of animal.E. the comparison is meaningless because the energy expenditure cannot be calculated.

In a study of the navigation abilities of Magellanic penguins (Spheniscus magellanicus), researchers failed to consider the influence of ambient environmental conditions. The navigation abilities of penguins tracked under calm sea conditions were evaluated by the same standards as were those of penguins tracked during turbulent sea conditions. The results of the study, therefore, ______13Mark for ReviewABCWhich choice most logically completes the text?Aare suitable for identifying conditions that the penguins can navigate through but not for identifying conditions that hinder their navigation.Bshould not be assumed as reflective of the navigation abilities of any penguin species other than S. magellanicus.Cmay indicate differences in navigation abilities among the penguins that may not actually exist.Dreveal more about the penguins’ navigation abilities under controlled conditions than in the wild.
