Flukes are among them. Flukes are the two lobes of the whale tail. While each whale has flukes, flukes themselves differ from species to species. In some whale species, flukes are so distinctive that researchers use them like fingerprints to identify individuals. whale uses his flukes to propel himself forward in the water and the flippers at his sides to steer and brake. As he swims, he moves the fluke up and down like a paddle, pushing himself forward with each stroke. Whales also use their flukes to get food into their mouths.
Effects on Physical Health. Introduction: During the relatively short history of the Nuclear Age, we have witnessed considerable damage to human physical health as a result of nuclear weapons. Long-term effects of nuclear explosions include cancers, tumors, genetic damage, infertility, and birth defects.
The full impact of nuclear fallout, however, depends on more than becquerels, which merely count the number of times per second that an unstable atom somewhere in the sample fires off a particle. These particles, and the differing amounts of energy with which they are ejected, have a wide range of effects on the body.
