Please answer this: I read this background article the other day: Scientists think that the earliest flowers attracted insects and other animals, which spread pollen from flower to flower. This greatly increased the efficiency of fertilization over wind-spread pollen, which might or might not actually land on another flower. To take better advantage of this "animal labor," plants evolved traits such as brightly colored petals to attract pollinators. In exchange for pollination, flowers gave the pollinators nectar. I am facing a new situation today: Scientists studied two groups of plants. Group F had plants with flowers, group W had plants that fertilize over wind- spread pollen. Flowering plants were more efficient. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group of plants attracts more insects?
++++++++
Answer: Group F

Please answer this: I read this background article the other day: Type 2 diabetes is much more common than type 1 diabetes. Type 2 diabetes occurs when body cells no longer respond normally to insulin. The pancreas still makes insulin, but the cells of the body can't use it. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. This type of diabetes usually develops in adulthood. However, it is becoming more common in teens and children because more young people are overweight now than ever before. I am facing a new situation today: John is very health conscious. He works out regularly, and maintains balanced diet. But his friend Keith doesn't care much about health. He indulges in fast foods, and never exercises. As a result, Keith has type 2 diabetes, but John is free from diabetes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is more likely to be overweight, John or Keith?
++++++++
Answer: Keith

Please answer this: I read this background article the other day: Animals may avoid becoming prey by living out of sight of predators, whether in caves, burrows, or by being nocturnal. Nocturnality is an animal behavior characterized by activity during the night and sleeping during the day. This is a behavioral form of detection avoidance called crypsis used by animals to either avoid predation or to enhance prey hunting. Predation risk has long been recognized as critical in shaping behavioral decisions. For example, this predation risk is of prime importance in determining the time of evening emergence in echolocating bats. Although early access during brighter times permits easier foraging, it also leads to a higher predation risk from bat hawks and bat falcons. This results in an optimum evening emergence time that is a compromise between the conflicting demands.Another nocturnal adaptation can be seen in kangaroo rats. They forage in relatively open habitats, and reduce their activity outside their nest burrows in response to moonlight. During a full moon, they shift their activity towards areas of relatively dense cover to compensate for the extra brightness. I am facing a new situation today: John was studying the species in African Savannah. He noticed that elands, which is a prey animal, are basically nocturnal. On the other hand, wild boars, another prey animal, are not nocturnal. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which species would show crypsis behavior, elands or wild boars?
++++++++
Answer:
elands
