148.216 Document Exercise‚ Assignment 1. Student ID # 99245875 THE FIRST SUCCESSION ACT‚ 1534. The Act of Succession 1534 is a statute issued by the English Parliament under the reign of King Henry VIII‚ which confirmed the annulment of Henry’s marriage to Queen Katherine and validated Henry’s marriage to Anne Boleyn. Also‚ through this Act the line of succession moved to the children of his marriage to Anne‚ or any future marriages‚ effectively removing Mary‚ Henry’s only surviving child

Lab: Sampling Bacteria Purpose: Refer to handout sheet. Materials: Refer to handout sheet. Procedure: Refer to handout sheet. Pre-Lab Questions: 1. Why is one dish being reserved for the class as a "control"? Having a controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar

The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are

Primary succession occurs in an area that has not had any previous soil. These areas lack soil vegetation‚ such as lava flows and exposed rock areas. Throughout the time‚ the materials help make the soil become richer. Once they die‚ their remains decompose into the soil causing grasses and trees to grow. The effects of a natural disaster common in the Great Plains that results in conditions for Primary Succession are tornadoes‚ blizzards‚ and floods. Tornadoes are strong winds that blow everything

micro-organisms that are in the human digestive system. Article of choice‚ (Adnan‚ 2010) Benefits of Microorganisms to Humans‚ Retrieved February 8‚ 2013. This article was of interest because there are many bacteria that we encounter in our daily lives and it was informative to know that all bacteria is not bad. In fact‚ there needs to be a balance between the two and by educating yourself with the smallest amount of new information is very helpful. Humans rely on micro-organisms for a variety

were measured and recorded. A hypothesis that was formulated before experimenting was‚ “If the type of disinfectant is Mouthwash‚ then it will allow for the least amount of bacteria growth because the chemicals present in Mouthwash combined with the acidic environment it bring will make it very hard to allow for any bacteria growth”. The independent variable in this experiment was undeniably

Viruses can infect all types of cells including plant‚ animal‚ protozoa‚ fungi‚ and bacteria. Virus composition is unique and does not resemble a living cell because they only contain the necessary parts to enter and leave an infected cell. A virus is a minute parasite (10 to 100 times smaller than bacteria) that is unable to reproduce by itself; however‚ once it infects a vulnerable cell a virus can make the cell’s inner workings produce viruses on its behalf. Viruses typically have either RNA

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful
