The Abyss - Unknown Death. It is an odd thing‚ one moment you’re sitting in front of a desk pondering how to answer the question in front of you‚ the next extreme pain as if you’re entire body is being roasted alive. Then‚ well nothing. Just darkness‚ dull and boring. Those were the thoughts of the boy as he drifted in the abyss. His mortal coil no longer existence‚ only a dimly lit sphere in its place. “I’m not sure what’s worse‚ exams or this...” he muttered inwardly‚ originally he hadn’t been

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

is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria can also be used in many other

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

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

Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

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
