The answer is: 3. He shows a range of emotions, including guilt.
A round character is behaves in a realistic way and grows in complexity within the story. In Act 3, Scene 3 from "Hamlet," Claudius is able to reveal his bad conscience after killing his own brother to become king. Thus, he exclaims his soul is as black as death and that his guilt cannot leave his soul. He even asks angels to help him get rid of his sin, so that his heart can become soft again.
Answer:
The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water. Sight is less effective for marine mammals because of the particulate way in which the ocean scatters light. Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine seismic surveys.[2]
