Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

Vibrio natriegens‚ who are curved-rod shaped microorganisms‚ they elongate to almost twice their own size and form a dividing wall in which splits the single cell into two daughter cells (Madigan et al.‚ 2015). There are four phases to bacterial cell growth: the lag phase‚ which is a period where bacteria are maturing and adjusting to the environment. During this phase‚ RNA synthesis‚ production of ribosomes‚ enzymes and other molecules occur (Mullenger‚ 1973). This is followed by the exponential

Modeling bacterial growth is important in maximizing the efficiencies of biological processes. Although there are many different methods of modeling bacterial growth‚ this experiment focuses on the Monod equations. However‚ in order to use the Monod equations‚ the maximum growth rate and Monod constant must be found. Here we show how the maximum growth rate and Monod constants can be obtained for Escherichia coli using M9 media in a bioreactor at 37 °C and 500 RPM. The maximum growth rate is also obtained

Investigating the Effects of Plant growth within Abstract This experiment was conducted to determine whether or not those plants can grow in low fertilized‚ less sun light and the control group. Each group had there own task of making sure that the plants were always water‚ each plant had the same amount of light on them. When the plants started to evolve each individual plant was measured of the height. Most of the plants grew faster than others but over the period the plants that grew faster

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter

Nicole Perry 7.06 Immune System Lab Report Thoroughly washing your hands can be one of the best ways to prevent the spread of pathogens that cause illnesses. Our bodies have several lines of defense to fight infections. It is very important to do what we can do to avoid the pathogens from entering our system in the first place. Our hands pick up microscopic pathogens from objects that were touched by people who may not have washed their hands very well. When we forget to wash our hands or don’t

Lab – Solubility Curve for Potassium Nitrate I. Purpose: To plot a solubility curve for potassium nitrate in aqueous solution. II. Safety: Wear eye protection throughout the experiment. Be cautious of hot water. Wash hands if you come into contact with potassium nitrate. III. Procedure: 1. Carefully weigh out your assigned mass of potassium nitrate on a piece of weigh paper. Carefully pour the sample into the large test tube. 2. Add 20. mL of distilled water to the tube.

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

Lab Report 7: Analysis of Cereal Introduction: 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
