P.S. I don't know what this worksheet is about but I tried my best to answer these questions

Action Potential Worksheet

1. Explain how an action potential and graded potential are different.

Action potentials are depolarization events that surpasses the threshold. Graded potentials have depolarizations that stay below thresholds or hyper-polarizations

2. Describe the following in your own words
a. resting potential

The membrane potential of a resting neuron

b. depolarization

Reduction in magnitude of the membrane potential

c. hyperpolarization

Increase in magnitude of the membrane potential

d. repolarization

Resting membrane potential reached by outflow of k+ from axon …show more content…
threshold

The value where if the membrane voltage surpasses the depolarization it continues as a depolarization event which results in action potential

3. What triggers an action potential? What happens to the membrane to trigger an action potential?

Stimuli causes the voltage gated sodium channels to open depolarizing the membrane to a point above the threshold

4. What is a positive feedback loop? How does a neuron create a positive feedback loop?

The stimulus is increased in the response. It causes the bext axon to open up its gates

5. What is the role of the voltage-gated sodium channels for producing an action potential?

The gated channels allow the sodium into the axon which causes the membrane potential above the threshold

6. What is the role of the voltage-gated potassium channels?

Potassium gates close after sodium gates close too

7. What would happen if the voltage gated sodium and potassium channels opened
a. at the same

three quarters did not like the outside preparation. The one quarter liked the outside preparation because they felt that the research gave them more background about the lab they were doing. They could spend the time researching online exactly what the experiment wanted us to do. The other three quarters of the group felt that the labs were too difficult, and that the descriptions on canvas didn't provide enough information to create a procedure. They would prefer to have a procedure given to them. New…

1. What questions (hypotheses) are addressed in the paper? Look in the Abstract. Can we calculate the equilibrium for the entire MgO-SiO2 range? If so, can we use these values to create a phase diagram for these minerals? What minerals are present in this composition range? 2. What are the main conclusions of the paper? Look in the Abstract and Conclusions. The main conclusions of the paper are that the most accurate part of the MgO-SiO2 range to calculate equilibrium is the middle compositions…

are found, they are then compared to normative data to obtain the SNR loss. List pairs 1-8 have ten sentences in each list, with one sentence at each SNR of +21, +18, +15, +12, +9, +6, +3, 0, -3, and -6 dB. List pairs 9-18 have eight sentences in each list, with one sentence at each SNR of: +21, +18, +15, +12, +9, +6, +3, and 0 dB. Scoring…

The balance of protons and neutrons in a nucleus determines whether it will be stable or unstable. If the nucleus has too many protons or too many neutrons this will upset the balance. The upset of the balance disrupts the strong nuclear forces and the nucleus becomes unstable. The graph below demonstrates the neutron to proton ratio: From the graph shown many stable nuclei have an equal number of protons to neutrons, these are elements in the lighter sections of the periodic table. The heavier…

Steve Chan- Our third quarter of IB Chemistry focused on quantitative chemistry, atomic structure, and the behavior of electrons in the atom. Much of this quarter focused on lab skills and we did experiments on titration, calculating formulas, flame tests, and using a spectrometer. During the 4th quarter we will looking at the topics of periodic trends, chemical bonding and structure, and organic chemistry. For all students reading the text of the chapter would be very beneficial before new material…

block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling? 0.04(300) =0.5+0.04v 12=0.24v V=22.22m/s 6. Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass…
