The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets, respectively, were allegedly reporting higher amounts of iron in their products than actually existed, as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze the products and use the data to determine the true amount of iron in each product, as well as confirm that the iron was usable by the human body. The methods used to analyze the products, data, and results will be provided in the sections below.…
Eight different prepared types of media were provided to use to identify the unknown bacterium. They were a Gelatin Tube, MR Tube(Methyl Red), VP Tube(Voges-Proskauer) Urea Tube, SIM Tube(Sulfur Indole Motility), Citrate Slant, TSIA Slant (Triple Sugar Iron Agar) and Oxidase. Each one of the tubes and slants were inoculated using either the streaking or stabbing technique with one of the colonies from the growth of the unknown bacterium.…
Put the 1.5 Volt battery across the y-input. Put the switch on Direct Current. Then measure the number of divisions that the dot jumps. Reverse the polarity of the battery and measure the number of divisions again.…

Then pour the liquid from the cup into the graduated cylinder. Record how much liquid was in the bowl (the amount of ice melted). After recording your results, clean and dry the cup and graduated cylinder. 14. Repeat step 13 with the three other bowls.…
My prediction, being a well educated guess, I think shooting from the stool the plastic ball will be able to travel farther. I never really considered gravity as a factor on the trajectory of the ball because I only thought about the weight of the plastic ball and the force and speed of how fast the plastic ball is being fired out of the projectile launcher. Then keeping in mind the angle of the plastic ball being fired, the ball will travel farther around a 30-50 degree angle. From those angles and the plastic ball being fired from a high elevation, the plastic ball would travel a little farther…

Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon, Fork, chopstick, and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food, the environmental chances, and see who were going to come out with the highest fittest. Each type utensil (bird beak) was place on a table (environment) with a food but as they keep on reproducing the environment keep on changing meaning they went form grabbing the mixed food from the table to grabbing Jelly-beans from table to grabbing jelly-beans from the carpet to grabbing popcorn for the carpet making it hard for some utensil (bird beak) to grab the food and surviving which eventually caused them to die. Not only did the environment change but the food source also chance. It went form mixed food to jelly beans and popcorn but as the food change and the amount of food got limited causing the non-fitness to die of hungry and those how had great fitness to survive.…
Background Information: My research was conducted to explain how populations evolve by means of natural selection. In 1859, an English naturalist by the name of Charles Darwin first suggested an explanation for how evolution occurs, a process he called natural selection. Natural selection can be defined as the differential survival and reproduction of individuals with different phenotypes resulting from interactions with the environment. Evolution is the process by which different kinds or organisms are thought to have developed and diversified from earlier forms during the history of earth.…
Obtain an ice bath. 12 ml of concentrated sulfuric acid was gathered, cooled to 0 degrees Celsius, and put in a 125-ml Erlenmeyer flash. Then 6.1g of methyl benzoate was added. Then cooled in an ice bath to 0-10 degrees Celsius. A Pasteur pipette was used to add a cooled mixture of 4-mL of concentrated sulfuric acid and 4-mL of concentrated nitric acid.…
As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse, blood pressure, respirations, hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail.…
