We talked about the Doppler Effect for sound waves. Electromagnetic waves exhibit the same type of effect. Explain in detail how Doppler shift is used in astronomy, weather forecasting and radar.

1. You identify a mutation in roses for the red pigment molecule; the pigment molecule is encoded by the gene RED.

The mutation you identified creates a much smaller, non-functional protein. You know the RED gene is haplosufficient.  

Is the mutation a loss-of-function or gain-of-function?

Is a heterozygote for the RED mutation (one wild type allele, one mutant allele) likely to look wildtype in phenotype (red colour) or have a mutant

phenotype (not red)? Explain your answer.

2. In a population of sneetches there are three body shapes: diamond, triangular and skinny. Body shape is controlled by two genes.

You breed a true-breeding diamond sneetch to a true-breeding triangular sneetch and all the offspring are diamond shaped.  

You then intercross the diamond F₁ and out of 64 offspring: 36 are diamond, 24 are triangular and 4 are skinny shaped. What best explains the inheritance pattern of sneetch shape? Explain your answer.

In the Deep Sea Kraken tentacle colour is determined by the presence of two pigment molecules. The pigment molecule/tentacle colour is normally controlled in the tentacle cells as follows:

• Precursor pigment molecule 1 is a colourless molecule. It is normally converted by Enzyme 1 into a blue pigment molecule.
• Precursor pigment molecule 2 is a colourless molecule. It is normally converted by Enzyme 2 into a yellow pigment molecule.   
• If both blue and yellow pigment molecules are present in the tentacle, the tentacle appears green.

A. One true-breeding Kraken line  (line A) has a mutation in the core promoter of the gene for precursor molecule 1 (mutated allele -> p^1A).  The mutation prevents transcription.  Presuming everything else about the line is normal what colour would you predict the Crake eyes to be in this line (line A)?  Explain your answer.

B. Another true-breeding Kraken line (line B) has a mutation in the gene for enzyme 2 (mutated allele -> e^2B). The mutation prevents conversion of the precursor molecule into the yellow pigment (only the colourless precursor is present).  If you crossed line A (from the question above) with line B what colour(s) would you find amongst the offsprings's eyes? Explain your answer.

You are a dragon breeder and have discovered that some of your dragons have a rare disorder that causes them to suffer progressive neurodegeneration leading to an early death. Unfortunately the disorder does not become apparent until after they have reached reproductive age.  This means that some of your healthy looking dragons may soon succumb to the neurodegenerative disease. It also means that “healthy” is not a good criteria to use when setting up future breeding because dragons who are “healthy” upon reaching breeding age may still develop the disease later.

Luckily there is a microsatellite marker that is located very close (on the chromosome) to the gene that when mutated causes the neurodegenerative disease. Below is the pedigree and microsatellite typing for one dragon family.  As the neurodegenerative disease allele is extremely rare you can assume anyone outside the family does not have the disease allele.

You have affected information for generation I and II (symbol filled in = affected = neurodegenerative disease) however the individuals in generation III are too young to show the condition (regardless of whether they have the affected genotype). Letters on the pedigree refer to the microsatellite alleles shown in the gel on the upper right. The chromosome region is also shown for your information.

A . What is the most likely inheritance pattern of the neurodegenerative disease? Explain your answer.

B . You type generation III for the microsatellite alleles A, B, C and D and find that III-1 inherited microsatellite allele B from her mother.  Given the inheritance pattern, and distance between the microsatellite allele and the gene of interest, what is the likelihood III-1 will have the neurodegenerative disease? For full marks you must show your work or explain your answer.

To show your work you may type in a description or attach an image.

3. Please list the 4 key supply side growth factors we discussed, and discuss their viability in terms of getting our economy growing again, given that today our economy is not growing.

a. The slides should provide you with what you need here.

b. The issue of viability – if the economy is growing slowly or not at all, do we have any chance of achieving success with each of the 4 growth factors? What will likely cause us problems? What approaches could we use to increase our odds of success? You need to think carefully on this one.

4. Creative problem solving

Scenario #1:

The rate of growth in the US economy is currently 0.5% annually. Your mission is to increase our growth rate to at least 4% annually, without setting off unacceptable levels of inflation. You have the tools of fiscal and monetary policy available.

a. Present your solution to the problem – write it down first.

i. Strategy for creating your solution:

1. First identify a specific natural resource and think through how having more of it or a better quality of it could lead to significantly increasing the GDP growth rate.

2. This will lead you to a general solution to the problem.

3. Write it down! The explanation of the solution should take at least one good paragraph!

4. Determine what will be required to make the solution happen, typically it is money.

5. Think of ways to use your fiscal and monetary policy tools to get the needed money.

6. To attack the problem you must select at least one Monetary Policy tool and one Fiscal Policy tool.

b. Write down the names of the one fiscal policy tool and the one monetary policy tools you picked.

i. Remember – for this question you need one Fiscal Policy tool and one Monetary Policy tool.

c. Explain why you picked the tools that you picked and why you did not select the other choices.

i. Specifically explain what is good about the tool you selected and what is not so good about the tools

you did not select? Do this for

both the monetary and fiscal policy tool that you selected. The key here is to use some decision criteria in making your choice.

d.,Thoroughly and completely explain how your solution would work to solve the problem. You must include and explain the use of your monetary and fiscal policy tools and indicate the impact your solution would have on the key economic variables. Please present your answer using a chain of events format. Be specific. I need to see the detail.

One can consider an IS and other technologies as a solution to most business challenges and problems experienced; this is one way of understanding more about information systems and often reffered to as a problem-solving approach. As an analyst you will learn more about problem-solving and create solutions to business problems, you will build great experience fo your career as an analyst. Your knowledge gained in problem- solving and information systems will be beneficial for both you and your employer.

Discuss in detail the simple four-step process model that you would use to solve problems in a business. 20 MARKS

you will include information about the health services your patient received. In this section, include the types of doctors your patient has seen and why. Discuss how he or she was diagnosed with the illness, how he or she stays informed about his or her illness, and what treatments he or she is receiving. Discuss the adherence (or nonadherence) to the treatment. If your patient is not yet at this point, discuss what steps you will use to help him or her adhere to treatment. Include in your discussion ways that communication could have been improved in the treatment process.

While performing his routine internal audit of Some Co’s payroll records, Baxter noticed that salaries and wages expense, including overtime pay for Q1 2018 had increase 17% over the previous quarter and 10% over Q1 2017. Baxter found these increases to be unusual given the recent layoffs at the company and its efforts to keep overtime pay to a minimum. He is aware that pay raises, capped at 1%, were issued in Q1 2018, but these alone do not explain the large increase in salaries and wage expense.

After some initial inquiry, Baxter learned that Some Co’s controller, Derek, had covered for the human resources manager while she was on vacation for two weeks during Q1 2018. Baxter is concerned that this breach in separation (segregation) of duties might have set the stage for payroll fraud. He is especially concerned about the possibility of a false salaries and wage scheme.

Create a planning form shown in class: Red Flags, Documentation, Testing, Why Not Fraud to show Baxter how you are going to investigate the situation.

Assume you have completed the investigate prepare an interoffice memo case study format to detail your findings for Baxter.
