Gold(Au) - Gold is a highly sought-after rare metallic element. For many centuries gold has been used for money, jewellery and ornamentation symbolising wealth and prosperity. Like other precious metals, gold is measured by troy weight and by grams. When it is alloyed with other metals the term carat (or karat in the USA) is used to indicate the amount of gold present. Pure gold is twenty-four twenty-fourths (24/24ths) gold, and is called 24-carat gold.
Reptiles are a group (Reptilia) of tetrapod animals comprising today's turtles, crocodilians, snakes, lizards, tuatara, and their extinct relatives.
But they also eat small animals, other reptiles â and other alligators! Crocodilians (crocodiles and alligators) are reptiles. Reptiles are animals that come from eggs, like birds. Reptiles are cold-blooded animals â they need the sun to stay warm. There are many insects that look like flowers and plants, but some reptiles do, too. Turtles and tortoises are two amazing, and quite different, species of reptile.
