How does the contraction time of a typical finger twitch compare to the relaxation time?
Exercise 2: The Effect of Weight on Finger Twitches.Questions:1- Discuss how do the amplitudes of the finger twitches with different weights compare to each other?2- Why did the amount of work decrease when heavier weights were used?3- Is there any correlation between the weight moved and the contraction or relaxation times of the twitches?
Exercise 3: Stimulus-Response.Questions:1- At which stimulus current did the finger first show a twitch? Why didn't a finger twitch occur at a lower stimulus current?2- How does the finger twitch amplitude increase when the stimulus current is increased?3- Is there a stimulus current at which the amplitude of the finger twitch is maximized?4- Above a certain stimulus current, the amplitude of the finger twitch no longer increases. Why does this happen?
Exercise 4: Summation and Tetanus.Questions:1- At which frequency did summation first appear? At which frequencies does incomplete tetanus occur? At which frequency did complete tetanus first occur?2- How much greater than the amplitude of a single twitch is the amplitude of the tallest twitch during summation or incomplete tetanus?3- How much greater than the amplitude of a single twitch is the amplitude of complete tetanus?4- After the stimulator is turned off, the relaxation time after tetanus is much longer than relaxation time after a single twitch. Why?5- What is the name for the decrease in the level of constant tension that occurs during tetanus?
In many countries, conservationists are trying to design national park systems so that "islands" of natural area (the big parks) are connected by thin "corridors" of undisturbed habitat. The idea is that this arrangement will allow animals and plants..
For a given reaction, G = -4 kcal/mole and the energy of activation for the uncatalyzed reaction = 5 kcal/mole. You add an enzyme, after which the activation energy decreased to 3 kcal/mole.
Complete a chart by identifying six actions that reduce the risk of infection and strengthen the body's immune system. In the second column, explain how the action reduces risk of infection and strengthens the body's immune system.
Give a mechanistic explanation for finding which is consistent with all the data. Explain your reasoning
Filling out two Punnett squares for a cross between a male with blood type B and a female with blood type AB. Build two Punnett squares and answer the following questions about them.
Do you really think the age of the man is main in determining the chance of chromosomal abnormalities? Why or why not with appropriate reasons. Describe a single meiosis event.
On the coding strand above, indicate where you would expect FRP to bind to the DNA. In one sentence, describe why the decision makes sense.
The value of neutrons and protons a molecule have determine a molecules "Molecular Weight". An important part of working a laboratory involves making molar solutions.
How various ATP equivalents are required to synthesize de novo one molecule of IMP, starting from ribose-5-phosphate? Presume that all required precursors in the pathway are present.
Explain at least one historical extinction with parallels to the extinction threats facing the bog turtle. When allosteric effector X binds to enzyme #1, enzyme stops working. However, the speed of reaction can be altered by adjusting the concentrati..
Explain how one of these main concepts is connected to your own personal observations. Clearly describe two methodological problems associated with the way Scientists study the topic.
Think about the following hypothetical scheme of determination of coat color in a mammal. Gene A controls the conversion of a white pigment P 0 into a gray pigment P 1 ;
