through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the 20 MWCO membrane because it does not ionize. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Glucose will diffuse through the 200 MWCO membrane because its MW is 180. The MW of the protein

Absolute Threshold and Differential Threshold Our five physiological senses have unknowingly fooled us – on a regular basis‚ no less – to the benefit of marketers and manufacturers. By exploring the psychological and physiological concepts of human perception‚ companies are discerning the differences of absolute and differential thresholds and applying it to marketing their products and effectively influencing consumer’s buying decisions. Once a product’s thresholds are distinguished‚ companies

neuron carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons

Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight
