PREDICTIONS 1. Exceeding the threshold depolarization at the trigger zone ______ the likelihood of generation of action potential.Increase 2. Action potential amplitude: doesn’t change with the distance 3. Increasing frequency of stimulation to the trigger zone:doesn’t change the number of action potentials MATERIALS AND METHODS Experiment 1: Effect of Stimulus Strength on Action Potential Generation 1. Dependent Variable-membrane potentials 2.
Humidity: Humidity in the inlet air should be as minimum as possible and dehumidified air should be used for faster drying rate because the rate of drying increases as the humidity of inlet air decreases. 3. Air flow rate: The rate of air flow should be controlled properly in order to get effective use of drying air. As the flow rate of air increases, the drying rate also increases and the cost of drying also increases. If drying air is kept in contact with the drying material, a proper heat transfer and mass transfer takes place and thus drying cost decreases.
Extra glucose cannot be used because of insulin deficiency and and blood glucose level rises, which contributes to further, adding to the osmotic diuresis. 4. What acid-based disturbances commonly occur and why? Arterial blood pH less than 7.30, serum bicarbonate level less than 15 mEq/L (15 mmol/L), and moderate-large ketones in the urine or blood ketones. 5.
Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA. The reduction in the elongation of VLCSFA and a diet low in VLCSFA will slow the demyelination
Primary succession isn’t likely to occur in the UK as there isn’t much bare rock left. Secondary succession is when an area that was once colonised by plants, then the plants are suddenly removed. For example in a forest fire, as a result of this succession has to start again. Secondary succession is much faster than primary succession and will reach climatic climax much sooner. This is because there will still be a lot nutrients and soil left behind from the previous ecosystem.
Which substance, water or the buffer does a better job of maintaining pH when small amounts of strong acid are added? The buffer does a much better job at maintaining pH. 3. Compare what happen to the pH of flask 2 to what happened to the pH of flask 4 when NaOH was added. Both flask’s pH went up 4.
if you were to have a larger hole in your aluminum cap, you would be losing vapor to the room. If this is the case then you would have a falsely high weight of vapor. It seems that you take a known volume of vapor and condensed and weigh it b) Water vapors condensed under the aluminum foil before the final weighing. If Water vapors condensed under the aluminum foil before the final weighing, the final weight would be lower than the fact. There will have some error.
Reddens skin and increases risk of skin cancer later in life. c. Electrolytes- electrically conductive substance containing free ions d. Glucose- Sugar used by cells in the body for energy e. Melanin- Pigment in the skin associated with coloration. 2. He lost approximately 10% of his total water volume. He would see a decrease in urinary output as his kidneys worked to maintain volume in the body.
Lower light frequencies had a more immediate effect than higher light frequencies. Question 2: Does the chart provide information suggesting saturation of rate as a function of increasing intensity? Justify your answer. Yes, the increased light intensity causes results in a slower rate of photosynthesis. This is because of the aquatic environment in which Elodea is found.
However in the long run consumers will realize the effect of changes in price and they will find new alternative products like kitchen towels or sponges etc. So therefore long rung price elasticity of demand for paper towels is higher. Moreover, not like non durable goods, price elasticity of demand for durable goods like televisions are higher in the short run compared to long run. Because if price of television increases, consumers will defer buying or they will delay purchase. So demand decreases sharply.
