  What Are Proteins? Proteins are very important molecules in cells. By weight, proteins are collectively the major component of the dry weight of cells. They can be used for a variety of functions from cellular support to cell signaling and cellular locomotion. While proteins have many diverse functions, all are typically constructed from one set of 20 amino acids. Examples of proteins include antibodies, enzymes, and some types of hormones (insulin). Most amino acids have the following structural properties: A carbon (the alpha carbon) bonded to four different groups: A hydrogen atom (H) A Carboxyl group (-COOH) An Amino group (-NH 2 ) A "variable" group Of the 20 amino acids that typically make up proteins, the "variable" group determines the differences among the amino acids. All amino acids have the hydrogen atom, carboxylic g...

Crocodiles are large reptiles found in tropical regions of Africa, Asia, the Americas and Australia. They are members of the order Crocodilia, which also includes caimans, gharials and alligators.  There are 13 species of crocodiles, so there are many different sizes of crocodile. The smallest crocodile is the dwarf crocodile. It grows to about 5.6 feet (1.7 meters) in length and weighs 13 to 15 pounds (6 to 7 kilograms).  Crocodiles have powerful jaws with many conical teeth and short legs with clawed webbed toes. They share a unique body form that allows the eyes, ears, and nostrils to be above the water surface while most of the animal is hidden below. The tail is long and massive, and the skin is thick and plated.  All crocodiles have a relatively long snout, or muzzle, which varies considerably in shape and proportion. The scales that cover most of the body generally are arranged in a regular pattern, and thick, bony plates occur on the ba...
