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

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

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

These factors expressed in the question affect the population density of a country or location immensely. Firstly relief‚ when we talk about the relief we talk about highlands and lowlands. Although immediately we like to think that most of the world’s population live fairly low down it is in fact the case that 80% of the worlds population live 500 metres above the sea level‚ this is actually fairly high up. What we might have been thinking of are the mountainous areas of the world like the Andes

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).

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

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
