Lab 1: Determining the pK a of PNP PNP or paranitrophenol is an organic compound that undergoes changes when the pH is manipulated of the solution. PNP is also an acid/ base indicator. The compounded starts off as internal conjugated ring with the hydroxyl group and the nitro group single bonded to the aromatic ring. This occurs at the pH of 5. At this point the aromatic compound is colorless and is in the ultraviolet range. However‚ as the pH begins to increase the hydroxyl group deprotonates

once-healthy neurons (nerve cells) in the brain stop working‚ lose connections with other brain cells‚ and die. While everyone loses some neurons as they age‚ people with dementia experience far greater loss. Researchers are still trying to understand the underlying disease processes involved in the disorders. Scientists have some theories about mechanisms that may lead to different forms of dementias‚ but more research is needed to better understand if and how these mechanisms

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the

Vance Campbell NT1210 – Intro to Networking Lab 3.1 to 3.4 3.1 1. Why would a three-layer model of communication that has the layers physical‚ network‚ and application be insufficient to adequately describe network communication? A. Because there is no transport or application layer. 2. What is the history of the OSI reference model? How did it come about and why was it created? Use your textbook and Internet research to support your answer. A. It was created to standardize the way

Homeostatic Mechanisms Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state‚ while the world around it is changing constantly. There are many steps in the process of homeostasis. First‚ there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center‚ which decides the response. The information entering into
