and soil microbes. In some complex forests‚ there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

Water pollution in China started with industrial development and has become more one of the most devastating environmental problems faced by the country today. From the chart‚ we can see that as the country’s GDP rises‚ the volume of wastewater discharge increases as well. This suggests that to achieve a rise in GDP‚ the environment has to be sacrificed. The reason for this is that wastewater treatment techniques and facilities have fallen far behind from the growth of industrial production and

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Nowadays‚ water pollution is a big problem in Vietnam and many researchers have been studying it. Accordingly‚ there are two main reasons of water pollution in Vietnam. The weakness in industrial wastewater management is the main cause of water pollution in Vietnam. Many industrial facilities use freshwater to carry away waste from their plants into canals‚ rivers‚ and lakes. Most of the enterprises don’t have any wastewater treatment system and many industrial zones don’t have a central wastewater
