Answer to Question 1

Toothed whales are active predators with a high brain-weight-to-body-weight ratio who can locate and even stun prey using echolocation. Baleen whales filter krill and other zooplankton from water near the surface. Both of these marine mammals are insulated by thick layers of blubber, breathe through nostrils on top of the head, and form complex social groupings.

Answer to Question 2

A fish's drag is determined by frontal area, body contour, and surface texture. The most effective anti-drag shape is the tapering torpedo-like body plan common to faster swimming fish.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
