How to Write Discussion (Bio Lab Report)

...The Discussion should be written after the Results section so that you have a good idea of what the experiment has demonstrated. The discussion section should definitely have a statement of your expected findings (Pechenik, 86). This should include your hypothesis and a brief statement about why these types of results are expected. There should also be a comparison of how your actual results related to your expected findings (Pechenik, 86). Here, you should state whether or not your results supported or didn't support your hypothesis. In addition, the degree to which the evidence supported your hypothesis should be stated. For example, were the results completely supportive, or were there variances? There should be an explanation of unexpected results (Pechenik, 86). When looking for possible explanations, consider the following: Was the equipment used adequate for the task? Was the experimental design valid? Were the working assumptions made correct? A common mistake that many writers make is to blame themselves for the unexpected results. Unless you actually made a mistake following the methods of the experiment, and could not go back and correct it, do not make up such errors to explain the variances you observe. Think about and analyze the methods and equipment you used. Could something different have been done to obtain better results? Another possibility to consider is if the experiment was conducted under factors that were considerably different from those described...

Yeast Culture Lab

...Yeast Culture Lab BIO/315 April 22, 2014 Annissa Furr Yeast Lab Yeast, is a microscopic one celled organism that belongs to the group of organisms that is called fungi. They are single celled organisms that have a scientific name of Saccharomyces cerevisiae. Yeast can have many purposes but the main purpose of yeast is to help the fermentation process. Yeast is a living organism known as a fungus and it gets its energy source from sugar. Yeast can also be used in creating certain medical intentions that heal wounds and reduce inflammation because of the large amount of hormones and enzymes. In reference to yeast reproduction depends on the type of species because they can be either asexual by mitosis or sexual by budding. Consumption talked about the use and rate of use of a primary consumer that needs photosynthesis in order to create energy from CO2. Death is in reference to a population and refers to the toll of death in a population. Hypothesis This labs main objective is to test cultures referring to yeast. The hypothesis is that the yeast will grow in all the environments that it is placed in but it will thrive in the environment that has sugar that is because yeast uses sugar as an energy sources naturally which will make the yeast generate more. The yeast could be identical in all the environments but most likely the situation will be that the yeast grows rapidly in the sugar. This hypothesis needs to be tested and in order to do that their...

Why (a) do you suppose Union Planters purchases investments, rather than simply making loans? Why does it purchase investments that vary in nature both in terms of their maturities and in type (debt versus stock)? 1. They may have excess funds that they havent loaned out yet and instead of having the money just sit there the bank manager may decide that it could earn more revenue by choosing to invest. 2. Depending on the situation the bank manager may also feel that they can make more money by investing the excess funds rather than lending the money out. For example right now interest rates are at an all-time low and they may feel like the return on the interest is not enough compared to investing. 3. The bank manager may feel that these investments will mature and be worth more in the future so they may choose to hold long term to create more revenue. (b) How must Union Planters account for its investments in each of the two categories? 1. Trading securities Balance sheet at fair market value a. Gain/Loss reported as part of income 2. Available-for-Sale Balance sheet at fair market value a. Gain/Loss Comprehensive income/ separate from Stockholders equity until realized 3.

...Course: Bio 102 Instructor: Marina Yoffe Assignment: Lab report (Introduction and discussion) Introduction The way in which different organisms acquire oxygen in exchange for carbon dioxide has truly evolved. The exchange of carbon dioxide for oxygen is essential for the survival of organisms that need to produce the energy molecule ATP through the process of cellular respiration. Respiration (breathing) is the way organisms exchange gases with their environment (White and Campo 2004). During cellular respiration organisms break down energy rich macromolecules such as starch to make ATP in a chemical reaction where oxygen and water is involved (Ege R. and A. Krogh 1914).The use of oxygen is very important; therefore the efficient acquisition of oxygen is very necessary for an animal’s survival. Depending on what type of organism is involved, our sources of oxygen are different and occur through diffusion. Terrestrial animals obtain oxygen through the air while organisms living in water depend on the oxygen from the water. Unlike terrestrial animals, the amount of oxygen for animals living in water is limited based on the amount of oxygen that has dissolved in the water. Since an adequate amount of oxygen is necessary, animals developed respiratory organs to help them ventilate and obtain as much oxygen from their respected sources as possible (W.C and R. Oesting 1934). One organism that has developed an efficient way of acquiring oxygen is fish. Fish use a counter-current exchange...

Yeast Culture Lab

...Yeast Culture Lab Introduction Yeast is a one-celled, microscopic organism, which is part of the fungi kingdom. Yeasts do not make up a single group (Smith & Smith, 2012). Yeasts use organic material as a means of making energy, which make them chemoorganotrophs (Smith & Smith, 2012). Carbon is procured primarily from hexose sugars, such as fructose and glucose. Yeast need either oxygen for aerobic cellular respiration or for species that are anaerobic, but also have aerobic methods creating energy (Smith & Smith, 2012). There are no species of yeast species that are known to grow only anaerobically. Yeasts thrive in an environment with a slightly acidic (Smith & Smith, 2012). The reproductive cycle of yeasts can be either asexual or sexual depending on the species. The most widely seen method of growth in yeast is asexual reproduction referred to as budding (Smith & Smith, 2012). Reproduction in reference to yeast depends on the species; the species can be both asexual by mitosis and sexual by budding (Smith & Smith, 2012). Consumption refers to use and the rate of use of something such as how a consumer, such as a primary consumer like a tree would use photosynthesis to make energy from carbon dioxide. Death in reference to a population is referring to the rate of death in that population (Smith & Smith, 2012). Hypothesis The primary goal of the yeast culture lab is to test a theory involving samples of yeast cultures grown...

Pfizer Case Analysis

...1) After spending years of effort to integrate Warner Lambert and Pharmacia into Pfizer, should its management have avoided another huge acquisition like Wyeth? Should Pfizer have gone after smaller bio tech firms in a series of small acquisitions in 2008 and 2009? A number of these bio tech firms could have been acquired for the $68 billion price of the huge Wyeth acquisition. Present arguments for and against buying several small firms versus one large firm. In my opinion, when it comes to the option of bigger or smaller firm acquisition, Pfizer should have invested in a large acquisition like wryeth. This is because Pfizer’s focus is not really on how many firms it can acquire but proceeds and profit margins these acquisitions can bring in. Basing on the case, its previous large acquisitions such as Warner Lambert and Pharmacia. In 2000 and 2003 where quiet good investments bringing in large profit margin of up to 90% from the Warner. A large problem of staffing is also worsened by over acquisition. According to the case overtime acquired firms have brought in excess staff for Pfizer and this has become a problem as managers for each line have increased and thus larger costs in terms of salaries as well. Larger firm acquisitions have also evidently brought stronger products than Pfizer itself can produce. Drugs such as Lipitor from an acquired firm brought in sales of about 12 billion annually while Pfizer produced drugs have failed i.e. T-pill Furthermore larger...
