and the time that used for the experiment to last was enough to allow sufficient osmosis to occur. However if I was to repeat the experiment I might well increase the time of the result to allow more osmosis to happen and possibly find out the saturation point of the chips. The range of concentrations was adequate but I would possibly create more concentrations if I repeated the experiment so that I would have more varied results‚ i.e. 0.10m‚ 1.15m‚ 1.20m‚ and so on. This way would have allowed

The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages. What is the cough reflex?

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Cari isn’t getting adequate oxygen because the pressure of fluid and the mucus buildup in her lungs. This is not allowing her lungs to expand so she can get the breath her body needs. The fluid buildup and the pressure are not allowing her oxygen to disperse to the areas it needs. How would Cari’s lung compliance (the effort required to expand the lungs) be altered as her alveoli fill

A) How could an infection in Cari’s nasal passage and pharynx spread into her sinuses? a. Her infection was able to spread to her sinuses because her sinuses became an area that her nasal passages and pharynx could drain into. In here the drainage just sat there and became a breeding ground for bacteria. B) What is the Cough Reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? a. The cough reflex is used to get things like irritants and fluid which

minimum of 20-30 minutes to view the result. In 1974 Takuo Aoyagi a Niigata University student disclosed his first Pulse-Oximeter for the use of pilots in World War 2. He set about searching for a non-invasive way of monitoring arterial blood oxygen saturation. Nellcor’s pulse oximeter was put on the market in 1983 and this used his theory developed in 1974. By 1987 Pulse Oximetry became part of a standard procedure in administrating anaesthetic. The use of oximetry quickly spread to other hospital
