The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007).

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

Hypothesis: The purpose of this experiment was to investigate the question will different food sources affect the level of activity of detoxification enzymes in bean beetles? The class alternate hypothesis is different food sources will affect the level of activity of the detoxification enzymes in bean beetles. The null hypothesis is the different food sources will not have any effect on the level of activity of the detoxification enzymes in bean beetles. Experimental design: The independent variables in this experiment were the types of beans (bean 1 was mung beans and bean 2 was adzuki beans) and enzymes assays used.

The purpose of the Unknown Lab is to practice and implement all that was learned in this microbiology lab this semester about the different test used in identification of an unknown bacteria and to effectively identify an unknown bacterium.

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

Mary Martinez is a 72 year-old female that is here in Prep and Holding for a scheduled elective right knee replacement surgery. I am performing a final pre-op exam at 6am. The patient is awake, alert, and oriented to name, place, and date. Patient has no known allergies. Patient stated her past medical history included: atrial fibrillation, hypertension, coronary artery disease, Type II diabetes mellitus, hyperlipidemia, and osteoporosis. Medications were reviewed with patient. Patient stated taking Coumadin, aspirin, metformin, metoprolol, calcium, and simvastatin. The last time, she has taken her medications were last night at 2000, including her warfarin and aspirin. She has been NPO since midnight. Physical assessment was performed. Patient complains of chronic pain in the right knee. Pupils are equal and reactive. Lung sounds are clear with auscultation on all lobes without any respiratory distress noted. Respiratory rate is 18 breaths per minute. Patient is on room air with oxygen saturation of 97%. Heart sounds are irregular with no murmur noted. Heart rate ranges from 92 to 120 beats per minute (bpm). Blood pressure is 140/67. Labs were reviewed. Abnormal values were International normalized ratio (INR)

My patient Mary Ramussen came to the clinic for dental hygiene services. She is a 66 year old lady taking several medications. All of her vitals were within normal limits at her visit. Vitals are very important to take because a patient may not have any symptoms. Medications can have many contraindications, adverse reactions, or an interaction with other medications. It is important to have knowledge of medications and how to avoid adverse reactions or toxicity. Some medications can interact with local anesthetic with vasoconstrictors and cause effects on the heart. Knowing all medications that a patient is taking is important for knowing what over-the-counter medications to recommend post treatment. Some medications

Per medical report dated 11/4/16, the patient’s medications include Ultracet 37.5/325 mg, Lodine 400 mg twice a day (on hold until April 2017) and Zanaflex 4 mg twice a day.

Discussion The data derived from the experimentation is shown in Table 1 and visualized in Graph 1 above. Graph 1 has an increasing trendline and supports the hypothesis that apple juice production efficiency will increase as the concentration of the enzyme pectinase increases. It has been proven that an increase in the enzyme concentration increases the frequency with which the enzyme and substrate collide, thereby increasing the rate at which the enzyme-substrate complex is formed and the rate of reaction. However, there is also a limit to how much one can increase enzyme concentration as there will eventually be more enzyme molecules present than the substrate. Effectively, there is a point at which a further increase in enzyme concentration will have no effect on apple juice production efficiency as some enzymes will become redundant due to the lack of a substrate to bind to.

The overall objective of the experiment was to compare the stress response two yeast strains, S. pombe and S. bayanus. We also looked at what genes were involved in ESR. The environmental stress tested was sorbitol treatment. In S. cerevisiae, the addition of sorbitol to the yeast growth media resulted in hyperosmotic shock similar to if the yeast were exposed to potassium of sodium chloride (Gasch, 2014). We compared the gene expression changes between the three species.

In February of 2017, I began a five month experiment testing the effect of fertilizers on algae growth. It began as a simple idea for a biology class, and evolved into an original complex of measurements, data, and results. The hypothesis, if the concentration of fertilizer in a solution containing algae is increased, then the algae growth will also increase, was proven correct in the first 20 days of the experiment, but disproven in the second 21 days. The highest rate of growth during the first time period was in the solution with the high levels of fertilizer. However, the second time period of the experiment showed that the most stable population was the solution which lacked fertilizer.

Proposition Motion: This house believes that humans and all other organisms did not evolve from one organism but rather God made each and everything the way it is from the beginning. Species can vary slightly in appearance like a poodle came from a wolf, but they can't change species like a wolf came from a fish. ------------------------------------------------------------------------------------------------------------------------------- Opening Statement: How did all the events that lead to this moment happen so precisely?

The patient was on hydromorphone for his abdominal pain due to liver disease, deferoxamine mesylate to treat secondary hemosiderosis, insulin due to diabetes mellitus, folates for sickle cell anemia, sertraline for possibly depression due to the hepatitis C, lansoprazole for stomach acid balance, promethazine for pain, and digoxin for cardiomyopathy.

What is academic writing? A simple definition of academic writing is a form of writing that refers to writing done for several reasons. However, a broad definition is any writing done to fulfill the requirements of a college or university. Academic writing is also writing that is used for publications that are read by teacher and researchers or presented at conferences. A prime example of academic writing is lab reports. Lab reports are a form of writing that provides formal record of research or an experiment. These reports consist of objectives, procedures, and results that should be specific enough that interested readers could replicate the experiment. When doing research on lab reports I learned about how a lab report is its own
