Science Folio Chapter 5 B6D5E1 Title: Importance of maintaining the cleanliness of air Introduction The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night. One of the most important factors drawing international attention which is

field of biological sciences‚ treatment of diseases and protection against pathogens have become more complex than ever. Technology sheds light on how to treat diseases‚ thus different quantitative experimental techniques and mathematical analyses for improving biological research are available‚ yet healthcare costs are skyrocketing‚ and the knowledge on how macromolecules work and how cells regulate gene expression has been a quandary. Biology is a highly fragmented science with delicate details

Organization (WHO) etc. All municipal (public) water supplies must be measured against these standards. Testing how ground water is affected by different contaminants was the bases of the experiment. II. Body Paragraph #2 – Objective~ in this lab we explored how contaminates affect the water supply. The main objective for this experiment is to see how the contaminants will affect the ground water. III. Body Paragraph #3 – Hypotheses~ a. Oil hypothesis = I hypothesize that the oil with

10.10.2012 Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Lab Questions: Unit 1 Autopsy of a Crime Scene 1. Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory‚ who is one individual that contributed to modern genetic analysis? What did this person contribute? - The DNA Analysis Technique is the best choice because no two individuals have the same DNA. This makes it easy to determine a match between the person the blood came from and the blood sample. Alec Jeffrey’s came up with the first genetic profile

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
