Step 1: Familiarize yourself with your tutoring options

Begin by familiarizing yourself with the tutoring options available to you, to do this follow the directions in the learning assistance page from the introductory module. I highly recommend using Valencia’s tutoring over Brainfuse, but either will count for credit.

Step 2: Attend tutoring

Next, attend tutoring a maximum of 4 separate times for a minimum of an hour each time (the sessions have to be on different days you cannot attend tutoring two times for 2 hours or one time for 4 hours). You have all semester to complete this assignment so I am confident that you are capable of making time in your schedule for your education 😀

Before a Session: Prepare for a tutoring session the same way that you would for your own personal study session. Jot down the concepts that you want to cover in that session and problems that you want to work on. Good places to start looking for ideas of what to ask during tutoring are the weekly learning objectives for this class. You will benefit more from tutoring if you come with concepts and questions prepared, BUT it’s always better to attend (unprepared) than to never attend.

1. Axons in the brain have smaller diameters than motor neurons; 0.6 ?m is a typical value. Most connections are short range, with an average axon length of about 700 ?m. The resistivity of the 7-nm-thick axon membrane is approximately 4×107 ?; the dielectric constant is 5. Model the axon as a cylinder. (6 pts)

Find out and show your work

(a) the resistance in M?,

(b) the capacitance in ?F, and

(c) the time constant in ms of the axon membrane?

2. The giant axon of a squid is 0.5 mm in diameter, 10 cm long, and not myelinated. Unmyelinated cell membranes behave as capacitors with 1 ?F of capacitance per square centimeter of membrane area. When the axon is charged to the ?70 mV resting potential, what is the energy stored in this capacitance? (4 pts) Show your work

3. A myelinated nerve fiber has a 4.0-?m-diameter cylindrical axon covered by a 1.0-?m-thick layer of myelin. No ions pass through the axon membrane, which is sealed by the myelin, but an action potential at a node causes an ion current to flow along the axis of the axon. The axon is filled with cytosol, whose resistivity was given in Chapter 24 as 0.50 ??m The dielectric constant of myelin is assumed to be 5.0, the same as that of the cell membrane (8 pts) Show your work.

a) What are the capacitance in pF and the resistance in M? of a 1.0-mm-long segment of a myelinated nerve fiber? Use the average radius of the myelin sheath for calculating capacitance.

b) What is the time constant in ?s of this RC circuit

I’m working on a geographic information writing question and need an explanation and answer to help me learn.

This is the writing component of the class and is worth 10% of the final grade.

Each student must pick a topic relating to physical geography (water, disasters, the environment, global warming, etc…) and write a one-page letter to a specific policy maker at any level of government addressing your topic and your suggestions for action.

Recall that this letter should be no more than one-page in length (12 size, normal font), single-spaced and be addressed to an actual person/entity with their address (you do not need to use your personal address and can instead use the University address)

Grading will be based on the presentation of your topic and the information used to back up your position (60 pts) as well as the writing capability displayed (40 pts).

Use a friend proofread your essay. Once you have completed your essay and had it proofread, please be sure to save your file as either as Word (.doc) or Adobe (.pdf) file, naming it with your last name, first initial, and the title “policy letter” as demonstrated by the following example: JudkinsG_policyletter.

You will then click on the “Browse My Computer” button at the bottom of the Webcampus page describing the assignment to attach your completed essay from wherever you saved it locally.

Please also monitor any feedback we give in the event that we are unable to open your attachment due to a corruption of the file. We will then ask you to email it directly to us.

1. Read the Dunn v. Reeves case in its entirety.

2. Read “A Guide to Reading and Analyzing Cases.”

3. Read “IRAC for Law 003 Students.”

4. Write a summary of the case using IRAC as the organizing tool. In addition to the IRAC headings, I want you to include a heading entitled FACTS. Under the FACTS, please write a few sentences on the case’s path to the US Supreme Court. In other words, a brief timeline/chronology. Then write the content of IRAC.

Remember, your brief must have these headings.

F: FACTS

I = ISSUE

R = RULE OF LAW

A – APPLICATION/ANALYSIS

C = CONCLUSION

5. The brief should be NO fewer than 2 pages with double spacing in between the headings.

6. Once you begin there is NO time limit but there is a DUE DATE. Please do not procrastinate as there will be no extensions of time or make ups.

To complete each scenario assignment:

1. Read the attached scenario pictures.

2. Compose in a Word document and be sure to address, at a minimum, the following questions:

• Why do you feel the way you do about the issue presented?
• Of the four responses offered in the scenario, which do you think is the most ethical and why?
• Which ethical theory would you use to support your stance? Why does this theory work?
• Which ethical theory (of the 6 approved ones ONLY – Kant; Act Utilitarianism; Rule Utilitarianism; Care Ethics; Virtue Ethics; and Social Contract) would you apply to this topic to defend your stance? A) In this reflection you must first define the key terms of the debate (for example, define what Euthanasia/Abortion/Stem Cell/Public Health/PreNatalTesting/Animal Research/Health Care, etc. means and what are the different types depending on which topic you are discussing)B) Define and explain the ethical theory you chose (show me you know exactly what the theory is and does – in your own words)C) Present the evidence both pro and con and follow up how using your ethical theory is the best way to determine whether or not your stance is really ethical

4. Support your conclusions with evidence and specific examples from the textbook, including a minimum of one theory of ethics to defend your stance.
