Bacteria are among the oldest species in the world.They both incerease in number and comply with nature very quikly so‚they maintain their species.Therefore‚bacteria have been the most common type of species according to number.Hence‚bacteria had been classified in order to make analysis.easily.Bacteria can be classified into three main categories on the basis of their nurition:saprophytic‚parasitic and chemoautotrophic bacteria. The Saprophytic bacteria are the first type of bacteria

Title L6 – Soil Permeability – Constant Head Test Introduction Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability‚ so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties

Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil
