that deals with microorganisms and their effect on other living organisms. Microbes are very small organisms which can only be viewed with the aid of microscope. Several groups of organisms that fit into this category are bacteria‚ cyanobacteria‚ fungi and protists. Within this group there are several species interesting to humans because of their ability to cause disease or their use in the food industry and microorganisms can be classified to unicellular and multicellular. These organisms are extremely

Also‚ there is a mycobiont‚ the fungus‚ whose symbiotic roles include the provision of structure and anchorage‚ protection from dessication‚ as well as providing the alga with inorganic nutrients and water. Moreover‚ lichens exhibit several unique features as it relates to their diverse morphology and ecology. With regards to their morphology‚ lichens have three major forms which are described as crustose (crusty)

Module 04 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates

Study A lot of our citizens are dependent on commercially available fungicides to control fungi growth at homes and businesses. However‚ most of these products are costly and contain dangerous chemicals that may harm human health and other organisms. The intention of this investigatory project is to manufacture an indigenous product that is effective‚ innocuous‚ and affordable to eradicate fungi‚ specifically bread molds. Mold is something that we often take for granted‚ as something

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Currently‚ there are fifteen subduction-related volcanoes active along the Cascade chain. Before 1980‚ the last one to erupt was Mt. Lassen in California‚ in 1914. In the mid-1970’s scientists were concerned that Mt. Baker‚ in northern Washington‚ might be the site of the next volcanic eruption‚ based on increased activity on the volcano. However‚ in 1978‚ Dwight Crandell and Don Millineaux of the USGS suggested that Mt. St. Helens was potentially the most likely volcano to erupt in the twentieth

cyanobacteria) and eukaryotes (fungi‚ mosses‚ ferns‚ gymnosperms and angiosperms) were included under ‘Plants’. It is based on the presence of cell wall. But prokaryotes and eukaryotes are widely differed in other characteristics. It included the unicellular and the multicellular organisms in same group. E.g. Chlamydomonas and Spirogyra were placed under algae. It did not differentiate between the heterotrophic fungi and the autotrophic green plants. Fungi have chitinous cell wall while
