Crystallization
This is a technique commonly done by chemists to purify compounds. During crystallization, an impure,solid compound is dissolved with a hot solvent. In the container the impurities and the needed compound move freely. When the solution cools down, the solvent can cannot hold all the solutes. Each solute will form a crystal. Therefore each crystal is made of only one molecule. Once it cools down if will be placed in a cold bath to complete the crystallization.
1. Mutualism ~ When both organisms benefit.
Egyptian Plover and crocodile
2. Commensalism ~ Only one organism benefits but the other remains neutral
Bird nest and Tree
3. Parasitism ~ Only one organism benefits and the other is harmed;
Dog and Ticks
Insects is largest if you want marine life it would be crustaceans which are the second largest group of arthropods
Explanation:
Mutations change an organism's DNA and affect how it looks, how it behaves, and its physiology. A change in an organism's DNA can cause changes in all aspects of its life.
Mutations are essential to evolution; they are the raw material of genetic variation.
