The Shang and the Chou dominated the political landscape as the most powerful of those states‚ but they did not exercise uniform rule over neighboring regions. When the Chou began to weaken around 500 BC‚ these independent states began to war among themselves over territory and influence. So chaotic was this period that the Chinese refer to it as The Warring States

(Include a description of the envelope‚ capsid‚ and core The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus‚ especially of small ones. Each capsid

Introduction A forest is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest

STAGE 3 - DEHUMANIZATION Historically‚ genocidaires have dehumanized targeted groups by depicting them as animals‚ vermin‚ insects‚ diseases‚ or tumors. This rhetoric constructs a narrative which justifies the "cleansing" of society. The mass murder of a people or peoples is facilitated through this process.

The study of microorganisms is called microbiology‚ a subject that began with Antonie van Leeuwenhoek’s discovery of microorganisms in 1675‚ using a microscope of his own design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the

Chapter 3 Adaptive radiation: it’s a cluster of closely related species that are each adaptively specialized to a specific habitat or food source. Adaptive zone: it’s the part of a habitat that can be occupied by a group of species that use the same resources in a similar way. Chapter 18 Explain the three modes of speciation (that make them become reproductively isolated). 1. Allopatric speciation: it’s the most common mode of speciation in large animals‚ and it occurs in two stages. First‚
