  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 back. Families a

THE  SOLAR  SYSTEM  consists   of  a  central   star  (the  sun) and  the  bodies that  orbit  it.These  bodies  include  nine  planets   and  their  61  moons ;asteroids ,comets,and  meteoroids.The  solar  system  also   contain  interplanetary    gas  and  dust.Most of  the  planets   fall  into  two  groups ;four  small   rocky   planets  near  the  sun (Mercury,Venus,Earth,Mars,)  and  four planets    further  out ,  the  gas  giants(Jupiter,Saturn,Uranus, and  Neptune.)Pluto  is  the  outermost  planet , except  when  it  passes  briefly   inside  Neptune's   orbit.Between  the rocky planets  and the gas giants   is  the  asteroid  belt ,  which   contains  thousands   of  chunks   of  rock orbiting   the Sun.Most  of  the   bodies  in  the  Solar System   move   around  he  Sun   in  elliptical    orbits   located  in  a  thin disc   around  the Sun's  equator .All   the  planets  orbit the  sun   in the  same  direction (anticlockwise)  when  viewe

Flower   gardening   consist  of  planting  flowery  plants  in  your  garden.Flowery  plants   are  of  many  types .They  are -Perennial   flower,Annual   flowers ,Biennial    flowers .

Biennial   flowers  or  plants -Biennial  plants  take  two  years  to   flower  and  go  to  seeds.These  plants are  not  good  for  flowers.
