Why does conduction velocity in an earthworm decrease when the earthworm is cooled.
Why does conduction velocity in an earthworm decrease when the earthworm is cooled.
3. Is there a relationship (correlation) between action-potential amplitude and conduction velocity? Why or why not? **please explain in detail
Find the drift velocity of conduction electrons in a gold wire of diameter 2.91 mm when a current of 0.159 A flows in it. The density of conduction electrons in gold is 5.90 × 1028 m–3.
is the mean drift velocity of a conduction electron due to typical electric fields used to measure resistance of a metal larger or smaller than its fermi velocity? why?
What specialized structures does an earthworm (lumbricus) have to acquire food and also to process the food it eats.
1.When a tsunami wave approaches the coast : - Does speed increase or decrease ? - Does height increase or decrease ? - Does wavelength increase or decrease ? Explain why.
1 a) Explain why a real gas that expands is cooled. Why is this effect only obtained at temperatures below 40 K for helium? b) Calculate the mean path and root mean square velocity of helium atoms at 101.3 kPa and 40 K. c) How would the medium path be affected for a gas trapped in a steel cylinder if heated?
1 Why does absorbance decrease when you add DCPIP to cholorplast and use light ? 2 Where would you find LHCII ? 3 What will happen if you put the gel against the positive pole and the membrane against ghe negative pole? 4 Why is immunoblotting better than using Commassie Blue? 5 If an herbecide was used and only co2 was generated and ATP was not generated, what was the mode of action of herbecide?
When does the slope of an Ellingham line increase and when does it decrease? Consider (i) a phase change occurs with increasing temperature on the reactants side (ii) a phase change occurs with increasing temperature on the products side
why the intensity of stokes line decrease when the temperature is increase? why the intensity of anti-stokes line increase when the temperature is increase?
Why, as we introduce taxes into the model, does the value of the multiplier decrease?
