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.
Even if individuals are not close enough to the nuclear blast to be affected by the direct impacts, they may be affected by radioactive fallout. Any nuclear blast results in some fallout. Blasts that occur near the earthâs surface create much greater amounts of fallout than blasts that occur at higher altitudes. This is because the tremendous heat produced from a nuclear blast causes an up-draft of air that forms the familiar mushroom cloud.
