list of items‚ both tangible and non tangible‚ that trees give us. First of all‚ as we all know‚ trees are the most important and the only natural source of oxygen in the atmosphere. Without oxygen[->0]‚ life is not possible on earth. Trees consume the carbon dioxide[->1] from the environment and give out oxygen which balances the amount of oxygen and carbon dioxide[->2] in the atmosphere. In addition to this‚ the wood that we obtain from trees is used in making paper‚ building houses‚ making furniture[->3]

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

Oxygen Delivery Devices Fact: Oxygen is a medication ordered by the physician Humans naturally breath 21% oxygen from the room air Normal oxygen saturation is 95-99% Clinically‚ if not receiving oxygen therapy‚ a patient on room air should have pulse ox reading of at least 92% or above Definitions: Pulse oximeter – a non-invasive way to monitor the percentage of oxygen carried in blood. Hypoxia – Impaired level of oxygen in the body Hypoxic - Lack of oxygen in the tissues‚ tissue starved

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

RED is taking its knowledge of high-quality cinema cameras to the smartphone industry with a new product. The Hydrogen One is RED’s bet to revolutionize the use of smartphones. Back in 2006‚ when RED was founded and showed its intent on delivering high-performance digital cinema cameras with quality of 35mm film and the convenience of pure digital‚ many people were skeptical and some even considered it a “scam”. After a 10-years background of providing unique high-quality cinema cameras with high-usage

Antioxidant Effects on Reactive Oxygen Species Abstract Antioxidants are among key molecules for a healthy living. Antioxidants are molecules that prevent damage of cells through inhibition of oxidizing agents such as free radicals. This experiment was aimed at investigating the role of antioxidant on the inhibition of reactive oxygen species. To demonstrate this‚ quercetin was used as antioxidant and its effect on reactive oxygen species examined. RAW 264.7 cells

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

THE CARBON OXYGEN CYCLE ROLE PLAY SCRIPT Narrator-Angela Narra-Czarina Cloud-Maureen Manggo-Carlos Car-Carlo Acacia-Carissa Animal-Josephine Narrator: Good afternoon block mates and Ma’am Claire. We are here to present you a role play about the carbon oxygen cycle. Let me first introduce to you the characters. [Characters from the middle back will step forward and play their roles.] First‚ Josephine as “Josepig”‚ Maureen as “Cloudreen”‚ Carlo as “Honda car-lo”‚ and the tree-yos;

of a component causes the equilibrium to shift to the side from which the component was removed. D. Is this reaction endothermic or exothermic? How do you know? When acid is added to water the reaction is strongly exothermic. Because the hydrogen ion is so tiny‚ a large amount of charge is concentrated in a very small
