of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the functions of human life. These enzymes are affected

dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer‚ pH chart. Substance of risk Nature

IMPROVED ASSAY This essay aims to critically compare and contrast the community psychology and public health approaches to social problems. It is imperative however to first explain what these two concepts mean before executing on how they compare and differ from each other. It would also be of significance to know how these concepts where established. Definitions Community psychology is that branch of psychology concerned with how people relate to community and society‚ and according to this

Abstract This is an experiment about procedures of calibration of a Coriolis mass flow meter. To do the experiment‚ water is pumped from a reservoir and its flow rate is set by a tap‚ the height drop is examined by eye and the time is recorded for a period during the flow. This procedure is arranged for the calibration of the Coriolis meter by comparing the calculated mass flow and the read value. Although‚ it is a reasonable aspect for the calibration which is comparing digital and analog measurement

There are certain big questions that philosophers have been puzzling over for centuries. Amazingly‚ many people ask these same questions in daily life. Reflect on these questions as related to each of the 6 branches of philosophy below. Write an APA-formatted essay of 3–4 pages explaining each of the 6 branches‚ describing a time in your life when you have asked similar questions. Discuss the specific circumstances that brought you to each question‚ and your conclusions. The questions are as follows:

The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite. It is chiefly used by the operating systems of networked computers to send error messages indicating‚ for example‚ that a requested service is not available or that a host or router could not be reached. ICMP can also be used to relay query messages. It is assigned protocol number 1. ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between

IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

Investigating pH Aim: To demonstrate dissolved carbon dioxide changing the ph level of substances. Materials: * 2 beakers * 2 straws * Stop watch * Distilled water * Lime water * Litmus Paper Method: 1. Pour 100ml of Distilled water into the first beaker‚ and label said beaker. 2. Pour 100ml of Lime water into the second‚ also Label beaker. 3. Test the two liquids with litmus paper and note the ph level‚ before any carbon dioxide has been introduced. 4. Place a straw
