Physics Lab Report Statement of the Problem: The problem that was arisen in Problem #5: Motion up an Incline was in reference to a change in acceleration in both an uphill and downhill motion. The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions. To obtain a secure conclusion this experiment required the use of a frictionless cart, an inclined ramp, motion sensor, meter stick, and assistance of computer
Lab Report Comparing Oxygen Consumption Rates in Different Mammalian Subclasses The purpose in experimenting with computer simulations was to compare oxygen consumption rates in different mammalian subclasses. We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased. This was also supported using a student's t-test. We also found that placental mammals had the
Biology Lab Report Lab No. 18: Biochemical Genetics: Smooth Peas Wrinkled Peas Data Presentation: The diagram of cotyledon for smooth and wrinkled pea is attached to the next page. The table of starch presents is below: Type of Pea Starch Present? (Color change) Smooth Yes (Dark blue) Wrinkled No (No change) Conclusion Smooth pea is dominant than wrinkled one, hence we can say the letter of allele which controls this characteristics is S. ‘SS’ and ‘Ss’ for smooth
Identifying macromolecules by using chemical testing in an unknown solution Leonardo Vargas, Hyat Farraj, Naraly Sosa, Alain Greenwald To be able to identify what kind of macromolecules a solution has, it has to be tested to be able to identify what macromolecules are present in the solution. Here we used only one test for each macromolecule that we are testing for. We tested for RNA, DNA, protein, sugar, starch, and lipid macromolecules. Using these kinds of test we were able to figure out, that
Lab Report The Effects of Drugs on Cardiac Physiology The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside

Cellular Respiration Lab Report I.Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There
7. Next, my lab assistants and I leveled the gel rig using small levels. I placed the levels on the surface where I would put the casting tray. We did this to make sure the gel hardened evenly. 8. We put the taped tray into the gel rig. Then, I put the comb into the casting tray on the edge of the tray. By putting the comb into the tray, this made sure the gel would have compartments to put the DNA into when the gel hardened and the comb was taken away. Afterwards, we put the gel rig on the counter
Lab Report Testing the Hardness of Water Water is the most important molecule that exists on the Earth. Without water living beings would not be able to live. Water is used for an immeasurable number of things. There are many properties of water, which makes this molecule so unique. One which people overlook is hardness. Hardness is defined in the Chemistry: The Central Science by Prentice Hall's as being "water that contains a relatively high concentration of Ca2+, Mg2+, and other divalent cations
Lab Report Testing Reactions with a Calorimeter A team was sent to the chemical manufacturing division of a small chemical company to help the technicians with experiments. Since the notes written by the technicians were inaccurate and unfinished, all of the experiments they had preformed needed to redone and documented correctly. The head of the company gave the new team the task of trying to figure out why some chemical reactions caused the reaction vessel to get cold and others caused the
Science Coursework The Resistance of a Wire Aim: To find out how the length of a wire affects the resistance of it. Knowledge: Ohms Law is a mathematical equation that shows the relationship between Voltage, Current and Resistance in an electrical circuit. It is stated as: , V = I x R , R = V / I , I = V / R Where · V = Voltage · I = Current (I stands for INTENSITY) · R = Resistance In order to understand what Ohms Law is all about you need to understand electricity
Lab Report Testing the Effects of Changing Surcrose Concentration on Osmosis in Plant Cells Aim To investigate the effects of changing the sucrose concentration on osmosis in plant cells. Plan Water passes into cells through a special type of diffusion called osmosis. Water molecules diffuse through the membrane from a weak solution into a strong solution until the concentration is the same on both sides. A membrane that allows only certain molecules to pass through is called a semi-permeable
Stop Animal Testing Animal testing is unsafe for all animals from around the world; indeed, “Over 100 million animals are burned, crippled, poisoned, and abused in US labs every year” (Top Five Shocking Animal Experimentation Facts). Various animal examinations, do not benefit the lives of guiltless animals. These analyses are to prove an element is safe to use on humans. The testing behind theses products are relatively dangerous to all animals. Fortunately, in today’s society, scientists have
for cannabis laboratory testing requirements: 1. Analytical chemistry – This is the science of quantitatively and qualitatively establishing the chemical makeup of a substance. This method is utilized to determine the cannabis potency level, analyze terpene profile, and in the detection of mycotoxins, heavy metals, residual solvents, chemical residues, and the presence of pesticides. Analytical lab testing methods are done previous to going on to microbiological testing methods. 2. Microbiological
Before the late 1800’s, DNA was never used in court cases. We did not have the equipment readily available. Then, in the late 1800’s and early 1900’s, DNA testing started to become very popular. This is when cases started getting overturned from wrongful court convictions. Which meant that the criminal that had actually committed the crime was on the loose in the community still able to do harm. In today’s generation, we still have many wrongful court convictions. Either due to their being little
decision to choose one vendor, Cerner, for their core clinical systems, including PowerChart and PathNet, the LIS. Optimizing integration between the EHR and LIS further improved efficiencies and accuracy of the entire process of ordering and resulting labs. The strategic decisions surrounding vendor selection and the accompanying outcomes at UAB were similar to the reading about UHIC’s decision to choose Epic Beaker (CP) as their LIS, which built off of the system-wide implementation of Epic’s EHR several
Animal Testing With the products that improve the quality of life popping up every day, it leaves you wondering how these products have become so perfected. A big part of that is in prior animal testing. While animal testing is sometimes highlighted from time to time, it is not commonly thought of when using a product. Highly rated shampoo? It was most likely tested on an animal beforehand. Animal testing in many cases can leave a physical and psychological impact on animals that are irreversible
complex and intricate maze of dark hallways. The doors read canine testing, swine feeding lab and primate testing environment. Upon looking into the dark rooms; one can make out the cages that once held chimpanzees. The sole purpose of this area is animal experimentation. This area, one of the most secure on the campus, has a separate dock and security cameras at every turn. I have had the opportunity to work in the animal labs of one of the largest corporations in the world. This discourse is my
Animal testing is a phrase that most people have heard but perhaps still unsure of what exactly is involved. Laboratories test cosmetic products and medications on animals to understand how the human body works. Rabbits, guinea pigs, and hamsters are used for laboratory experiments, which they all suffer during each medical procedure. Those who support animal testing may define it as an experiment that uses animals to benefit humans, where it saves lives and provides vital medical treatment. Regardless
