Some animals, such as dolphins, dogs, and African grey parrots, seem to exhibit cognitive functions typically associated with higher-order primates such as chimpanzees, gorillas, and humans. Some parrots, for example, have vocabularies of hundreds of words that they can string together in a comprehensible syntax. This clearly shows that humans and primates are not the only animals capable of using language to communicate. One parrot, named Alex, has been known to ask to be petted or kissed and will exhibit aggression if the gesture offered is not the specific one requested. Which of the following, if true, would most strengthen the conclusion above?A. Dolphins can be trained to assist divers in ocean rescues. B. Gorillas in captivity often learn hand signals for food and water. C. Dogs are capable of sensing their owners' moods and often exhibit concern if they sense sadness. D. Chimpanzees can memorize long sequences of key punches on machines that dispense food. E. Alex does not exhibit aggression when offered a gesture that he specifically requested.

E. Alex does not exhibit aggression when offered a gesture that he specifically requested.✔

Explanation:

A. Dolphins can be trained to assist divers in ocean rescues.❌

Option A States that dolphins went through some certain training. We can say training is a one-way process unlike communication which is a two-way process.

B. Gorillas in captivity often learn hand signals for food and water.❌

Options B can be considered wrong in this context as gorillas can be placed in the primate classes based on the argument.

C. Dogs are capable of sensing their owners' moods and often exhibit concern if they sense sadness.❌

Dogs are capable of sensing. In this case, it is not equivalent to communication.

D. Chimpanzees can memorize long sequences of key punches on machines that dispense food.❌

Options D can be viewed as wrong in this area as chimps can be categorized in the primate zone based on the case study.

E. Alex does not exhibit aggression when offered a gesture that he specifically requested.✔

It speaks about communications as Alex is interacting with humans as seen in this case, most likey its master.

option c is the correct answer.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
