Overview. Complex carbohydrates are made up of sugar molecules that are strung together in long, complex chains. Complex carbohydrates are found in foods such as peas, beans, whole grains, and vegetables. Both simple and complex carbohydrates are turned to glucose (blood sugar) in the body and are used as energy.
A turtle is an animal in armor. Much of its body lies within a protective shell, which has openings for the turtle's four chunky legs, short tail, and head. When danger threatens, many turtles pull legs, tail, and head into the shell.
Science: How Many Legs Does a Crab Have? True crabs as well as their close relatives have five pairs of legs, for 10 legs in total. However, some of their legs have evolved to serve purposes besides walking, such as self-defense, food acquisition and swimming.
