题目Some people say dolphins(海豚)are smart like humans(人类).They can think,understand and learn things quickly.In fact,dolphins have big brain(大脑)-to-body size ratio(比例),which is second only to humans.Dolphins use brains differently from the way humans do.But...
What makes dolphins so smart? Well, their brains, of course. Dolphins have large brains for their bodies. A bottlenose dolphin is second only to humans in the ratio of brain size to body size. Researchers have also pointed to the parallels in the organization of dolphin and primate brains ...
This known as the “Encephalization Quotient” (EQ) and is the ratio of brain size relative to body size. By this measure, brains with EQs larger than 1 are bigger than the expected size, while those with EQs less than 1 are smaller. Humans have the highest EQ at 7.4, but bottlenose...
45. Dolphins can see well in the water due to the way their retina collects the light. 46. The brain of dolphins is the second largest ratio between size compared to its body size; only behind humans. 47. It is possible for a mature dolphin to eat up to 30 pounds of fish per day....
THE BRAIN AS THE CENTER. Dolphins have larger brains than humans and a complex neocortex. When it comes to comparing the brain sizes of living creatures, it is done assessing the ratio between brain size and body size. The dolphin case is exceptional. They have brains larger than those of ...
The ratio between echo level and emitted click level at 0.5 m from the dolphin’s sound source was only − 23.1 dB in this case. In the FB case, a clear pattern of interference was observed due to both the acoustic properties and the shape of the foam balls. The sound waves were...
Seven days post infection no cytopathic effect (CPE) was observed and the flasks were passaged at a ratio of 1–5 but 24 h later small plaques developed in the flasks inoculated with both A and B samples of cerebellum (Fig. 3a,b). Plaques contained many multinucleated giant cells or ...

aIt should be made clear that the steam to fuel ratio of 6 is based on the amount of the acetic acid used exclusively for reforming and not the ratio in the total feed. 应该讲清楚它蒸汽到燃料比6根据用于改革而不是比率完全的数量乙酸在总饲料。 [translate] aI want to know whether you ...
Thebottlenose dolphin (Tursiops truncatus)is the second place in a list of species with a higher encephalization ratio (EQ), which compares the mass of the encephalon against its body size. In addition to a developed neocortex, the cerebellum has more convolutions (turns of the brain surface)...
