alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical usage. There are many different ways of permanently changing the land‚ from soil

Frogs re-evolved "lost" bottom teeth after more than 200 million years‚ according to new research. Tree-dwelling Gastrotheca guentheri are the only frogs with teeth on both their upper and lower jaw. The reappearance of these lower teeth after such a long time fuels debate about whether complex traits are lost in evolution or if they can resurface. Scientists suggest this new evidence identifies a "loophole" in previous theories. The Gastrotheca genus of frogs carry eggs on their backs Commonly

DNA-protein complex is called chromatin. It may seem paradoxical that proteins are added to DNA to make it more compact. However‚ if you have ever tried to store a garden hose‚ you know that it is much easier to do so if you begin by coiling the hose. Of course‚ coiling requires work‚ and energy is needed to perform work. Thus‚ within the nucleus‚ histones provide the energy (mainly in the form of electrostatic interactions) to fold DNA. As a result‚ chromatin can be packaged into a much
