Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

should be properly trained to carry out the use of this equipment. Site Security and Hoarding: Hoarding is used to separate the site from the public for security and liability purposes. It normally consists of a metal mesh type fence but on the larger sites a high timber fence may be erected for added protection. It is a very important aspect of the site layout as it reduces the risk of unauthorised access that may result in injury in which the contractor may be liable while also preventing materials

Objective: Motion on an Incline with Friction The purpose of this experiment is to prove that the experimental acceleration value calculated is close to the theoretical acceleration values by finding the tension force‚ normal force‚ kinetic friction and the coefficient of kinetic force from the data collected. Theory: The forces acted on an object can be divided up into many different components depending on what the object is doing. In this experiment‚ an object is sliding up an incline plane

component‚ and so on‚ until it reaches the source again. In contrast‚ a parallel circuit is a circuit in which the has more than one resistor and has multiple paths to move along. The main purpose of this lab was to prove the laws of Ohm and Kirchhoff. On another note‚ being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit. I believe that if we only have the

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things
