...Kayleigh Lanning Biology 101 Dr. Lazar June 10, 2013 In this lab the objective was to measure the absorbance of different wavelengths of light through pigments. First we separated the major pigments found in leaves of green plants then we transmitted different wavelengths of light through each major pigment. Activity one dealt with solubility of several pigments. The information given to conduct this experiment was that a chlorophyll a pigment will turn a blue/green color, a chlorophyll b will be a yellow green, carotene will be a deep yellow and xanthophyll will be a pail yellow. We were also given the fact that the most soluble pigment would be at the top of the chromatography paper. While separating the pigments, my group hypothesized that if we tested the pigments for solubility, then carotene would be the most soluble. The independent variable would be the comparison of the different pigments, and the dependent variable would be the solubility. In this experiment we used chromatography paper, spinach leaves extract, a lead pencil, a metric ruler, a paintbrush, one large beaker, 5-7 mL of solvent consisting of 10% acetone in petroleum ether and a paper clip. It was also important that we had access to a fume hood. The first thing we did was gather the materials. Then we got the ruler and using the lead pencil drew a line about 15 mm from the bottom of the chromatography paper (the long side of the page). After we did that we got the spinach leaves extract and with...

...Yeast Culture Lab I. Introduction 1. Yeasts are eukaryotic, unicellular fungi that inhabit liquid or moist habitats. They are heterotrophs and rely on complex organic substances for nutrition. Yeasts require oxygen for aerobic cellular respiration but some are also anaerobic with alternative aerobic methods for producing energy. They do not require light to grow and their temperature range varies which means they can survive in a multitude of different environments. Very common, they can be found anywhere, from occurring on the skins of fruits to residing in the intestinal tracts of animals as parasites. The most common method of reproduction for yeasts is asexual reproduction through budding. In this process, the parent cell’s nucleus splits and forms a daughter nucleus. The daughter cell grows on the parent cell until it is large enough to separate. Through cytokinesis, this ‘bud’ then forms a new cell. Less common is the method of sexual reproduction in which spores are formed. In this lab, I will be culturing four yeast samples under different conditions. The goal is to study the effects of limited reproduction, additional resources (nutrition) and predation on the yeast population. Yeasts play a very important role not only by serving as nutrient recyclers in nature, but by also being important for the food industry because they can convert carbohydrates to carbon dioxide and alcohols through fermentation. They are also used in cell biology research and produce ethanol...

What was violated in this data breach.( The VA Data Analyst’s and two supervisors that were reprimanded and demoted by the VA Secretary and the action is justified because the incident had been happening over the last three years and no one did anything to correct the problem or report it.) 8. If the database was encrypted because of VA policy, would this data loss issue even be an issue? (Data breach was violated because the information that the VA patients provided was supposed to be kept in save place) 9. What risk mitigation or security control recommendations would you suggest to prevent this from occurring again?( Even if the data was encrypted because of the VA policy, data loss would still be an issue because of all the personal information that could have been compromised 10.

...Mineral Lab Paper Week One Mineral Lab Geology SCI/245 Axia College Mineral lab Paper The four requirements for minerals are that they must be naturally occurring in other words they must appear in nature something that that was formed by the earth and not man made. It must be inorganic which means I must not be formed from an organic substance like a fossil of any other living creature. It must have a specific crystalline structure that is formed from simple salts and complex silicates. And it must have a definite chemical composition which defines the minerals structure. The way that you differentiate between minerals is by the way they react to specific tests like for instance the acid test some minerals will have a bubbling action and other one will have no reaction and by color minerals come in many different shades an colors. The six methods to tell minerals apart are the color test by looking at the mineral it can be classified by its color. Another method is the streak test which is the color of the mineral in its powered form this is the true color of a mineral specimen as it lessens the impurity impact and eliminates the light distortion from the crystal. The luster test refers to the absorption, refection, or refraction of light by the surface of a mineral. The fluorescence test in ultraviolet light, some mineral specimens appear to Florence due to the fluorescent mineral impurities or due to locality. Chemical composition is another method because minerals...

This experiment focuses on the ebony and wild type phenotypes. These phenotypes affect color. The ebony flies more dark and the wild type flies are much lighter. The ebony is recessive and therefore carries two copies of the recessive allele, therefore the Drosophila are homozygotes. But wild type is dominant, meaning that heterozygotes and homozygotes represent the wild type phenotype. A phenotype is a physical characteristic as a result of a genotype affected by its environment (Brooker et al, 2011). A genotype is the set of...

...Morgan Johnson (19407679) NS 1110 Friday Research Paper Lab 10 Morgan Johnson (19407679) NS 1110 Friday Research Paper Lab 10 The topic I chose for my research project is setting up a business on the Darknet. I think it would be more accurate to say that the topic chose me. I was originally browsing the internet on the various subjects presented to us in the assignment handout and had started reading a little about ecommerce when this topic jumped out at me. As I started looking into the other topics on the sheet, I couldn’t get the information about the Darknet world out of my mind. I think I have a bit of a fascination with the outer edges of society and that includes cyber-society. The secretive world of the Darknet is interesting in itself but setting up an ebusiness that may or may not provide illegal goods and services requires such an intricate system of safeguards that, for someone new to the tech world like myself, it is like opening the door to a bizarre and complicated dimension. Even after spending some time researching the subject, it would take hours more and I still would have barely explored the world of the cyber underbelly. The first thing a person needs to do when setting up a potentially questionable business, is to research various countries legal relationship with the country you’re based in. For the sake of this paper, we will assume we live in the U.S. Find out which have or don’t have Mutual Legal Assistance Treaties. When you figure...

...* * 1 2 3 4 5 6 7 8 9 Number 1 is pointing to the PS/2 inputs that would connect a keyboard or mouse to a desktop computer. These inputs are for the most part being “upgraded” to USB ports. USB inputs for these devices allow users the option of using wireless mice and/or keyboards. For obvious reasons this adds a great deal of convenience and takes away some of the clutter that wired keyboards and mice make. It also allows for users to use different types of mice, like the one I use. Not only is it wireless, it has a trackball as opposed to the typical mouse that you have to move around. I control the pointer with my thumb, and can use the mouse on any surface, including my lap. Number 2 is pointing to the Parallel port. Historically the parallel port was used for zip drives, scanners, external modems, sound cards, webcams, gamepads joysticks, external hard drives, and CD-ROM drives. As with many of the other ports, the parallel port is being replaced with the USB port for many of it’s past functions. However, if you still have a parallel printer, they do make a USB-to-parallel adapter. Number 3 is pointing to the serial port. There are quite a few devices that can be plugged in to this input, such as dial up modems, bar code scanners, printers, older digital cameras, networking, serial mouse, and what I would say is the most common use for this input, an LCD or other display units. Just like...

...Design Lab: Respiration The Effect of Heavy-Duty Exercise on the respiration of Homo Sapiens (Humans) Research Question: What is the effect of heavy-duty exercise (cardiovascular and other activities) on the respiration of humans? Background Information: In this experiment, trials will be conducted consisting of humans run up a set of stairs up and down 3 times as fast as they possibly can in order to put pressure on oxygen need to increase respiration needs. This will test the effect of a set exercise on the respiratory needs of a human. After this, they will have to do a set of 10 push-ups and 15 jumping jacks. If 10 push-ups are not possible, a substitute of 15 curl-ups should be administered instead. Hypothesis: When exercise is complete, the respiratory needs of one human should be significantly higher than it was previous to the exercise. Independent Variable: Human fitness level, exercise set Dependent Variable: How fast the human goes Controlled Variable: Temperature, time for exercise, amount of oxygen in air Materials: * Piece of paper for general observations as well as data recording * 4-6 humans * Timer (ipod, clock, something) * Water (if needed for human) Procedure: 1. Use the stairs next to the Biology classroom, select one human to go first and rotate turns until all humans have gone or until necessary data is gathered 2. Record the rate of exhales of the human (normal breathing) for 30 seconds and any other general...

...I began to feel like a lab rat when they did not know which type of contraceptives would be the best. They tried the Mirena, an Intrauterine device (IUD) which was supposed to last up to five years, which seemed great! But it did not last nearly five years. The IUD fell out a few months after, hopeful, the doctors tried it once again, and once again, it fell out. Both those times I had to go into the surgical Pavilion. I was scared equally those two times because of the anesthesia. The last time they gave up on it. Once again, I was their lab rat. They tried the normal birth control pills on a normal dosage. It did not work. They raised the dosage to two times a day. It did not work. I feared them raising my dosage to three a day because birth control pills are very expensive when you do not have Medicare or Medicaid. Thankfully they didn’t. They left the dosage at two a day, but decided to include the Depo-Provera, a shot which is given every three months. To this day this hasn’t failed me at all. I go every three months for my shot, and take my pills every day. I finally stopped being their lab rat. My mom has told me the story of her making her way to the hospital just as she got out of work on the day of my last...

...separately[1]. The purpose of this lab is to test six different inks to see if they are pure substances or mixtures. This lab also teaches how to identify a pure substance versus a mixture, and the process of using a chromatograph. To perform this lab, a piece of filter paper, a paper wick, alcohol (the solvent), and six different pen inks were used as an example of chromatography. The solvent hit the different inks and, if they were mixtures, separated the components of the ink. After this lab was over, it was found that three of the inks were...

...Term Papers COMPARING APA FORMAT IN A RESEARCH/LAB REPORT AND A TERM PAPER? WHAT IS THE SAME? * Margins (one inch) * Rules regarding quotations (long and short) * Rules for citations * Rules for references * Rules for page numbers * Rules for title page WHAT IS DIFFERENT? Parts * In a lab/research report, you test people/animals to collect data. You then statistically analyze that data and draw conclusions. Because you must report all these activities, a lab/research report must have a Methods, Results and Discussion section. * Term papers are usually about other people's research. Since you do not test people or animals yourself, you do NOT need a Methods, Results or Discussion section. Introduction * In a lab/research report, the introduction must explain what question your data will answer and how your study will help build a body of scientific knowledge. Because of this, the introduction of a lab/research report briefly describes related research by other people (that is, a literature review with citations).. * The introduction in a term paper is more like the Abstract of a lab/research report. It is an overview of the entire paper. In a term paper the literature review (with citations) is found mostly in the body of the paper. HOW TO WRITE A TERM/RESEARCH PAPER IN PSYCHOLOGY PURPOSE:A research paper describes and summarizes a specific area of research by providing a summary and evaluation of the research already done as well...

...Introduction Lab safety is the most crucial part when working in a laboratory. Following all the proper precautions and acknowledging the lab protocols will ensure that everyone in the laboratory does not get harmed in any way. The three modules reviewed in this lab included: personal safety protocols, proper hand washing techniques, and proper disposal practices. Reviewing and practicing all three of these modules helped me recall and understand the importance of lab safety. Methods and Materials The first portion of the lab was over proper hand washing techniques. Proper hand washing includes using water, soap, a nailbrush, and paper towels. First you remove all jewelry from your hands and wrist. Next, you turn on the water and then apply soap to your hands. You must rub your hands together and scrub for at least 20 seconds. During this process of scrubbing your hands, you will use the nailbrush to clean under your...
