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

Activity 6.2-Membranes Organize a Cell’s Activity Dissect a Plasma Membrane Objective: to understand the structure of a membrane 1. Why is the membrane described as a phospholipid bilayer? It is described as a phospholipid bilayer because there are two layers of phospholipid molecules. 2. How does the arrangement of the phospholipids form a bilayer? The phospholipids arranged in two layers so that the charged phosphate heads interact with the water on either side of the membrane‚ and the

Root Cause Analysis. Root cause analysis is an effective tool used in many industries‚ including healthcare‚ to establish a key reason that an outcome‚ that was not as anticipated‚ did in fact happen. In other words‚ what was the crucial reason for a specific outcome (Bohannan‚ 2016). Root Cause Analysis (RCA) is not a blaming activity but put in place for improving patient care. This may sound simple‚ but it is not as simple as it appears. There can be many causative factors throughout the many

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

Women: The Root of All Evil? Author‚ congresswoman‚ and woman of the year Clare Booth Luce once said‚ "Because I am a woman‚ I must make unusual efforts to succeed.

We need to understand the difference between a physical currency that is the basis for our lives and a material desire that is driven by greed. It is a fact

At the 90 second period it decreased by 4oC from 35.5oC to 31.5oC it then steadied out falling by 1oC per 15 seconds until the 120 second stop mark. For the 500mL beaker the temperature difference between the 15 second intervals were very different being more gradual with the temperature on average falling from 1 – 1.25oC per
