Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Title- Mitosis Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been reviewed

Universal Law of Gravitation in 1687. His law of gravity describes the force amongst every object that contains mass. Newton devised his idea of the law of gravity when he observed an apple fall from a tree. This then lead him speculating about whether the same force that was upheld by the apple was also maintained by the moon. Sir Isaac Newton then reached to the discovery that both the apple and the moon were motivated by the force of gravity. His law of gravity states that ‘every object in the universe

Salinity is the measure and concentration of all the salts dissolved in water. Usually measured in parts per thousand (ppt or )‚ ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less (University of Rhode Island). Many factors go into salinity‚ making water salty. To name a few‚ salinity affects the environment through sediment from rocks washes into the ocean‚ evaporation of ocean water‚ and sea ice formation are known to increase the salinity of the ocean (NASA). It

One of the oldest questions in history is why and how fast do things fall to the Earth? This was not far from Henry Cavendish’s goal. In 1798 Cavendish sought to find the density of the Earth which in turn can be used to calculate the weight of the world. His experiment however required him to calculate an undefined variable in Newton’s law of universal gravitation known as G or the gravitational constant. Cavendish through his experiment discovered that the Earth’s gravitational constant was 9.8

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species

Lab Report: Effects of Lysozyme Introduction: This report discusses an experiment that was done to demonstrate the effects of lysozyme on populations of Gram positive and Gram negative bacteria. Bacteria have a cell wall composed of peptidoglycan that gives the wall its strength. Gram negative bacteria have and extra component of lipopolysaccharide (LPS)‚ that is stabilized with magnesium ions‚ to their cell wall that further protects them. When Gram positive bacteria are treated with lysozyme

and then up again so I added pH buffer solution so the pH could stabilize at 8.1. After that‚ I decided to add water to keep the specific gravity from getting too high and maintaining stable. 3. What problems‚ if any‚ did you have with any of the fish or invertebrates in the reef tank? My main problem was that the anemone died because the specific gravity got too high. After that incident‚ I began to add water regularly to prevent an accident from reoccurring. 4. Describe
