Under the terms of the current contractual agreement, Burger Queen (BQ) is entitled to 20 percent of the revenue earned by each of its franchises. BQs best-selling item is the Slopper (it slops out of the bun). BQ supplies the ingredients for the Slopper (bun, mystery meat, etc.) at cost to the franchise. The franchisee’s average cost per Slopper (including ingredients, labor cost, and so on) is $.80. At a particular franchise restaurant, weekly demand for Sloppers is given by P = 3.00 – Q/800.

a.       If BQ sets the price and weekly sales quantity of Sloppers, what quantity and price would it set? How much does BQ receive? What is the franchisee’s net profit?

b.       Suppose the franchise owner sets the price and sales quantity. What price and quantity will the owner set? ( Hint:Remember that the owner keeps only $.80 of each extra dollar of revenue earned.) How does the total profit earned by the two parties compare to their total profit in part (a)?

c.        Now, suppose BQ and an individual franchise owner enter into an agreement in which BQ is entitled to a share of the franchisee’s profit. Will profit sharing remove the conflict between BQ and the franchise operator? Under profit sharing, what will be the price and quantity of Sloppers? (Does the exact split of the profit affect your answer? Explain briefly.) What is the resulting total profit?

d.       Profit sharing is not widely practiced in the franchise business. What are its disadvantages relative to revenue sharing?

I would like to work closely with you to refine my dissertation for completion in 30 to 60 days (my draft is 90 pages with references, when we add the final chapters, probably btw 100 to 125 pages.

My advisors would like me to focus on three of the 16 students (lowest, middle and highest performance on the tests and questionnaires and audio recordings) and do mini case studies of how they responded.

Research questions: How do students respond to different multi-dimensional learning materials in dissection activities?

Can virtual dissections/#D instruction enhance their engagement w/science dissections? (How they thought they took advantage of the different media in each condition with paper,live frog and virtual dissections?) Reframing: Can various forms of 3D instruction motivate / learning,

What are debits and credits? How are debits and credits used to record business transactions?  Why do accountants debit asset accounts to increase them but credit liability accounts to increase them? Why do accountants debit expenses to increase them but credit revenues to increase them?

A debit is an asset or increase in cash (left column). Debits normally increase assets and decrease liabilities and credits normally decrease assets and increase liabilities. A credit is a decrease in cash (right column). Debits and credits are used to record business transactions by the type of account that is used. Expense and assets are increased on the debit or left side and liability equity and revenue accounts are increased on the credit side. Every transaction must be balanced and in order to accomplish this, a transaction must be posted to an account on the left side as well as to an account on the right side…

Attention deficit disorder (ADD) is a syndrome in which a person has difficulty focusing sustained attention on a task for a significant amount of time. In some cases this is accompanied by hyperactivity as well. It is currently being diagnosed at an all-time high. Between 1989 and 1996, youth visits for ADD increased 90%, from 1.9% of total physician visits to 3.6%.

 

Now, a psychiatrist named Dr. Edward Hallowell is making a new distinction. He has described a similar set of characteristics in a large number of patients that he terms Attention Deficit Trait (ADT). It looks a lot like ADD in its day-to-day manifestation, but unlike ADD, ADT symptoms lessen when the sufferer goes on vacation or into a decreased sensory input setting for an extended time period (on the order of days or weeks). In such a long-term placid situation, the ADD sufferer’s problems continue unabated.

 

Imagine that you have the general set of symptoms described above. But which of the two syndromes are causing your symptoms: the disorder (ADD) or the trait (ADT)? Approach your problem using scientific methodology—developing a question, a hypothesis, an experiment, and a control for the experiment.

 

The initial question and the experiment that will be performed on you are provided. Your job is to state the hypothesis and to design the most important and most basic control for this experiment.

 

 

Your Question: What’s my problem? Is it ADD or ADT?

 

1.      Your Hypothesis: State your hypothesis based directly on the above question.

 

Your Experiment: Keeping your same diet, sleep habits, and basic activity level, you will be sent on a two-week vacation to the Bahama Islands. You will be given only a beach to walk on and your favorite friend to talk to, following which you will be asked to read and memorize 10 sequential definitions from a standard dictionary in 30 minutes.

 

2.      Your Control for this Experiment: You get a numerical result for the number of definitions you memorized. What does that number mean? Nothing—unless you have a control for your experiment. What is the most obvious control for this experiment?

 

Major Hint: The study guide for Quiz 1 indicates where this topic is covered in your text. The two figures in that section give you valuable examples. Remember, the initial question and experiment are provided here. Be careful to provide what the assignment is asking for.

 

Your assignment:

 

1)      Write out a testable hypothesis in a brief sentence. Derive it from the question asked above. (Be certain that the experiment addresses it!)

2)      In a second sentence, describe a basic, critical control situation (additional experiment?) that will give validity to the experiment described above.

Number your sentences with “1” and “2” and do not use paragraph form. The sentences must not be submitted as an attached document, but entered into the text box provided.

How would the financial statements be useful to managers and employees? How would the financial statements be useful to investors and creditors?

Financial statements alert investors of the risk that is involved in investing in the company. The information from these reports also allow investors to judge what type of return they will receive on their investment and it also helps them to determine whether to hold, buy, or sell. Creditors are concerned with any statistical financial information that helps them to determine the financial stability of the organization and whether the business will repay the loan payments on time. Creditors also want to determine the stability of the organization and understand where the money is coming in and where it is going out.

Managers need financial statements so that they can determine what activities within the organization are profitable or not. Managers also use this information to guide decisions, resources, and if operations should continue in the present manner…

My collected data is secondary data from RIOT company and Twitch TV.com Please follow the Guideline You need to explain how you are getting your data, from where or whom. You must explain how you obtained and analyzed your results for the following reasons: 1. Readers need to know how the data was obtained because the method you chose affects the findings and, by extension, how you likely interpreted them. 2. Methodology is crucial for any branch of scholarship because an unreliable method produces unreliable results and, as a consequence, undermines the value of your interpretations of the findings. 3. In most cases, there are a variety of different methods you can choose to investigate a research problem. The methodology section of your paper should clearly articulate the reasons why you chose a particular procedure or technique. 4. The reader wants to know that the data was collected or generated in a way that is consistent with accepted practice in the field of study. For example, if you are using a multiple choice questionnaire, readers need to know that it offered your respondents a reasonable range of answers to choose from. 5. The method must be appropriate to fulfilling the overall aims of the study. For example, you need to ensure that you have a large enough sample size to be able to generalize and make recommendations based upon the findings. 6. The methodology should discuss the problems that were anticipated and the steps you took to prevent them from occurring. For any problems that do arise, you must describe the ways in which they were minimized or why these problems do not impact in any meaningful way your interpretation of the findings. 7. In the social and bahavioral sciences, it is important to always provide sufficient information to allow other researchers to adopt or replicate your methodology. This information is particularly important when a new method has been developed or an innovative use of an exisiting method is utilized.

Liberty University BIOL 101 Individual Assignment 3 complete solutions correct answers key

The global community is plagued by increasing incidence of lung cancer, colorectal cancer, breast cancer, pancreatic cancer, prostate cancer, leukemia, non-Hodgkin lymphoma, liver cancer, ovarian cancer, and esophageal cancer. Other types of cancer exist but are less frequent. What is the scientific community doing to attempt to eliminate the most common forms of cancer that are ravaging society?

 

1.      Be certain that you have read your textbook’s chapter on cell division, specifically the last section on how cells become cancerous. This is context for completing this assignment.

 

2.      Watch the presentation (found in the Reading & Study folder of Module/Week 4) entitled “Ways to Fight Cancer.” Notice that the presentation outlines essentially 3 approaches to fighting cancer: a) reduction of cancer risks, b) correction of cancer genes, and c) destruction of cancerous tissue.

 

3.      In the “Individual Assignment 3: 10 Discoveries in the War on Cancer” document is a set of 10 scientists’ discoveries. Scan the discoveries briefly. Then open the assignment submission link in Module/Week 4. In the text box, number from 1 to 10 for the 10 discoveries listed in the document.

 

4.      Reflect carefully on the first discovery (#1). Would this discovery be more useful for (a) reducing cancer risks, (b) correcting/restoring cancer cells to normal, or (c) destroying cancerous tissue? After #1 in your list, place in parentheses the letter representing the approach to fighting cancer that will best be served by this new discovery. (More than one approach may be served, but which is most likely to be helped most significantly?)

 

5.      Repeat this analysis for each of the remaining 9 discoveries. Return to the “Ways to Fight Cancer” presentation as needed for additional perspective. When finished, your entire text box must be simple: a numbered (1–10) list of letters a, b, or c.

 

6.      Seven points are granted for each correct association, up to 8 correct. If you get any 9 correct out of 10, you get a perfect score (60 points) on the assignment.

 

Individual Assignment 3: 10 Discoveries in the War on Cancer

1.      Malignant brain tumors in adults are fast-growing cancers with median survival rates of 15 months, even with aggressive treatment. Researchers have been searching for genetic “signatures” (characteristic groups of cancer-causing genes) that could help in defining the kind of brain tumor the patient has. They hope to be better able to predict the course of the disease and the patient’s response to treatment.

 

2.      Tobacco smoking is the leading cause of preventable deaths worldwide. It is a risk factor for lung cancer and several other types of cancer. Results of analysis of the entire human gene collection (the “genome”) support some previous findings that a region of human chromosome number 15 contains one or more genes that are associated with smoking intensity (the number of cigarettes smoked per day) and the closely related trait of nicotine dependency.

 

3.      Immunologists are investigating ways to destroy lymphocytes (white blood cells of the immune system) that have become cancerous (lymphomas). A current drug, Rituxamab, contains antibodies that bind to the surfaces of these lymphocytes, setting them up for destruction by the cancer patient’s own immune system. They are currently seeking ways to modify the antibody’s structure so that it will attract the cancer patient’s “natural killer” (NK) cells to the lymphocytes. Success of this project will bring a multifaceted immune response against lymphomas and hasten their destruction.

 

4.      Virologists are modifying lentiviruses as vectors for carrying proto-oncogenes into cancer-transformed cells in culture. They are developing this virus for inserting the ras proto-oncogene directly into its correct location in the genome. The correct ras gene will already be linked to human DNA to either side of it and complexed with a recombination enzyme that will insert it into its correct location within the human genome. At the same time, the recombination enzyme will excise the defective oncogenic form of ras. The cells in culture should again come under normal hormonal control and require extra-cellular signals in order to continue dividing.

 

5.      Immunologists are working with a mutation (HER2) that is expressed on the surface of many breast, bladder, pancreatic, and ovarian cancer cells. They have made antibodies against this mutant surface protein. These antibodies have been covalently bonded to a “gene expression vector” that makes cells light up when incubated with luciferin from fireflies. The vector takes the gene for luciferin into the cancer cells. The researchers have shown that their antibody can accurately find and light up cancer cells. Their next step is to bond the antibody to an expression vector that carries the normal HER2 gene into mutant cancer cells.

 

6.      Biochemists have discovered a protein kinase enzyme named BRAF that is an important link in a molecular pathway that causes a cell to divide. Normally BRAF responds to signals coming from outside the cell—signals calling for the cell to divide normally under normal conditions. But there is a mutation in BRAF enzymes that causes it to activate the cell toward division continually. In this way it results in melanomas, thyroid, and ovarian cancers. Biochemists have also found a drug, vemurafenib, that binds selectively to mutant BRAF, totally inactivating it. Cells that have inactivated BRAF undergo apoptosis, a process that leads to cell death.

 

7.      Organic chemists are exploring structural variations of the organic compound avobenzone (1-(4-Methoxyphenyl)-3-(4-tert-butylphenyl) propane-1,3-dione) for inclusion in sunblock products. Avobenzone is known for its ability to absorb a broad spectrum of ultraviolet radiations, including UVB light (known to enhance the frequency of basal cell and squamous cell carcinomas [skin cancers]) and UVA rays (thought to increase the frequency of melanoma cancers). New variations in the structure of avobenzone are hoped to retain the ability to absorb harmful UV radiation while having an increased stability in the presence of that radiation.

 

8.      Molecular biologists have taken nanoparticle-sized spheres and used them to deliver a cell-killing toxin from bee venom to tumors in mice, substantially reducing tumor growth without harming normal body tissues. Nanoparticles are known to concentrate in solid tumors because blood vessels in tumors show “enhanced permeability and retention effect,” or EPR. Hence, substances such as nanoparticles escape more readily from the bloodstream into tumors and the generally poor drainage of lymph from tumors further helps trap the particles in tumor tissue.

 

9.      Biochemists are analyzing the many, many components of red meat (beef, pork) to determine which component, if any, will cause increased colorectal cancer rates in mice when the component is administered orally. Studies have shown that higher colorectal cancer rates in humans are associated with higher consumption rates of red meat.

 

10.  Molecular biologists have developed a new sequence of human genes called an ankyrin insulator sequence. You place a new, corrected, or therapeutic gene within this sequence. Its role is to create an active area on a human chromosome where the new gene can work efficiently no matter what chromosome it lands on.
