Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology Dissecting set

Keanna Barnes Abstract Current studies on oncolytic viruses have been underway to ultimately reduce the casualties cancer brings upon citizens globally. Lately‚ a series of clinical studies have shown clinical response when vaccines are combined with other forms of treatment in patients with all sorts of different cancers. Although scientists may be tempted to combine an oncolytic virus with an already existing radiation or chemotherapeutic‚ the long term goals have to be realistic and rational

Exercise #5 Identification of Fungi Fungi‚ like bacteria‚ may be useful in industry but also problematic. Many produce important products including foods‚ chemicals‚ enzymes and pharmaceuticals such as antibiotics and hormones. Molds‚ however‚ in particular‚ are also common contaminants in industry. It is important to be able to recognize and identify them‚ therefore‚ in the laboratory. In today’s laboratory session you will examine some common molds and attempt to identify them. While the identification

Are Viruses Alive? For years‚ scientists debated whether or not viruses are living organisms. The most confusing thing about viruses is that they display characteristics of both living and nonliving beings (Lourerio‚ 2006). Even after years of research and argument‚ we have not come to a final conclusion to this mind boggling question: Are viruses alive? Viruses are miniscule parasites that spread infection through all species of living things‚ plants and animals. Parasites are completely dependent

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

Are Viruses Alive? 1. Describe how a virus differs from bacteria. Most Viruses are harmful and their only purpose is to invade a host cell‚ reproduce and destroy the host cell in the process. Close to 99% of bacteria are beneficial with only a few that cause diseases. Life on earth could not exist without bacteria. Bacteria produce nearly half of the oxygen found in the atmosphere. Viruses have no cells‚ nucleus‚ cytoplasm or cell membrane. Viruses consist of tiny particles of nucleic acid

Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several

predictable- always behaving or occurring in a way expected. Example: marriage‚ job‚ moving or living home‚ having children‚ retire‚ etc. 1) Marriage: it can be positive as an individual will learn to cope up with someone‚ will share bills and house with the partner so there will be no more stress of paying the bills alone and will start a family with partner. Negative effects is children could find it hard or uncomfortable if one of the parents remarry. Stressful marriage can lead an individual

Protists and Viruses A flagellum is a whiplike tail that helps organisms living in moist places to move The characteristics of protists is they are euckaryotic organisms‚ they are one or many-celled but do not have the complex organization found in plants and animals‚ and some make there own food and other can’t. Protists are plantlike‚ animallike and funguslike. A virus is a microscopic particles that make up either DNA or RNA core covered by a protein coat. Viruses are so small an electrn microscope
