A new study was released reporting that vampire bats may be unable to learn important information about food sources that make them sick. Most mammals are able to learn from their meal mistakes. Typically, if a mammal eats a novel food that later makes it sick, it will form an aversion to the food. This means the animal will learn not to return to that particular food source. Interestingly enough, vampire bats are unable to learn this lesson.In a recent study at the University of Toronto, several types of bats were used to test their food aversion formations: fruit bats, common brown bats, and vampire bats. In the research study, all three types of bats were fed meals laced with cinnamon, a spice they would be able to detect. After eating, the bats were given an injection that made them vomit. The next time the bats were fed, their food was again spiced with cinnamon. The fruit bat and common brown bat did not consume the food. They had learned from previous experience to avoid it. However, the vampire bat returned to the food source that made it sick. When results of other trials proved consistent, scientists were able to conclude that vampire bats are unable to form food aversions.Scientists are speculating that somehow vampire bats must have lost the adaptation that allows the formation of food aversions. They hypothesize that this may be related to the fact that a vampire bat’s diet consists mostly of animal blood, which contains fewer toxins than certain insects and plants that other bats eat. Because they encounter much less toxicity in their diet, there may be no need for them to form food aversions. Scientists suggest that further studies in which a variety of foods are used would be most helpful in determining what causes the vampire bats to return to food sources, despite the possibility of impending ailment.Milius, Susan.

A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.Which of the following, if true, would cast the most serious doubt on the accuracy of the group's contention?A) Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roostingB) Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humansC) Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South AmericaD) Raccoons and owls are shy and active only at night; yet they are not generally feared and persecutedE) People know more about the behavior of other greatly feared animal species, such as lions, alligators, and greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats

In addition to the answer that you have provided, for each of the remaining options you have not chosen, please give a persuasive reason for their dismissalTigers are carnivoresProfessor Julian Olodomongi says so, and he is an expert on TigersTigers are naturally meat eaters, because many years ago the most powerful witches on earth placed a spell on Tigers and forced them to be that wayTiger cells contain a gene that prevents their stomach from digesting plant cells.My science textbooks says Tigers eat meat but not plants.

cientists say that they are glad to have wolves around. Wolves often help other animals. Wolves must hunt, so they can survive. However, wolves cannot eat very much. After they eat some meat, they walk away. Then, other animals can eat the meat. These animals could die without this meat. Some of these animals cannot hunt.Do It!These other animals would die from _________.Press enter to interact with the item, and press tab button or down arrow until reaching the Submit button once the item is selectedA coldB fightsC hungerD sickness
