1. When comparing a range of viral populations in a particular year what characteristic is most associated with survival of the population to the next year.

A) a high rate of change in sequences at antigenic sites

B) a high rate of change in sequences generally

C) movement to a new host

D) ability to overwhelm the immune system

E) a low mutation rate

2. Some sharks migrate from the ocean to live in a freshwater lake. After a few generations scientists sequence an enzyme involved with moving ions across cell membranes in both the ancestral ocean population and the lake population. After correcting for the number of possible changes they found 3.3 nonsynonymous changes in the sequence for every synonymous change. This is evidence for which of the following?

A)No selection on the enzyme

B)Positive (directional) selection on the enzyme

C)Negative (stabilizing) selection on the enzyme

D)Ambiguous (disruptive) selection on the enzyme

3. Which evolutionary forces will tend to cause populations to diverge from one another genetically when they (the populations) are geographically isolated?

A) mutation, drift, selection

B) mutation, drift, migration

C) migration, drift, mutation

D) migration, selection

E) migration, selection, drift

At the end of the year, a company offered to buy 4,690 units of a product from X Company for a special price of $12.00 each instead of the company's regular price of $19.00 each. The following information relates to the 67,200 units of the product that X Company made and sold to its regular customers during the year:

Fixed cost of goods sold for the year were $130,368, and fixed period costs were $73,920. Variable period costs include selling commissions equal to 2% of revenue.

6. Profit on the special order is

7. Assume the following two changes for the special order: 1) variable cost of goods sold will increase by $0.90 per unit, and 2) there will be no selling commissions. What would be the effect of these two changes on the special order profit?

8. There is concern that regular customers will find out about the special order, and X Company's regular sales will fall by 500 units. As a result of these lost sales, X Company's profits would fall by

Part 1

Here is some code:

def foo(var):

    var = []
    var.append("hello")
    var.append("world")

list = ["bah"]
foo(list)
print(list)

Which Option is correct?

A) ["hello","world"] is output because python passes the list by reference and the list is changed inside the function.

B) ["bah"] is output because python passes the list by value so changes to the list in the function are made to a separate list than the one that is passed in.

C) ["bah"] is output because python passes the list by reference but a new reference is created by the first line in the function so subsequent changes are made to a separate list than the one that is passed in.

Part 2

Consider this code:

list1 = []
list2 = list1

list2.append(1)
list2.append(2)
list1.append(3)

Which option is correct?

A) list1 contains [3] and list2 contains[1,2]

B) list1 contains [3] and list2 references the same list as list1

C) list1 contains [1,2,3] and list2 references the same list as list1

D) list2 contains [1,2,3] and list1 also contains [1,2,3] but the 3 is stored in a different location than list2

Find the future value of the following annuities. The first payment in these annuities is made at the end of Year 1, so they are ordinary annuities. Round your answers to the nearest cent. (Notes: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in many situations, to see how changes in input variables affect the output variable. Also, note that you can leave values in the TVM register, switch to Begin Mode, press FV, and find the FV of the annuity due.)

A 37-year patient comes into the urgent care and presents with chest pain and hyperventilation. During the assessment process, his vitals are recorded, a brief health history is recorded, he is inspected visually from head to toe, asked about current medications and his chief complaints are addressed. Asking him to breathe through pursed lips or into cupped hands alleviates his hyperventilation. He was also given the option to hold his breath for 10-15 seconds at a time. After lying down for a few minutes, there was little relief for his chest pains therefore an ECG was conducted Recurring panic attacks and high levels of anxiety characterize panic disorder. Panic attacks can occur without warning or stressor however the patient mentioned being stressed due to taking on more responsibilities at work. He was diagnosed with panic attacks and prescribed paroxetine daily and lorazepam prn.

Two stress reducing techniques are medication and psychotherapy or cognitive behavior therapy. CBT is a model that challenges negative thinking and behaviors. It is rooted in the idea that attitude impacts behavior (Plehn, 2002). The meditation was not effective whereas the cognitive behavior therapy proved effective. I believe CBT helped because it allowed the patient to share his feelings in a structured yet intimate environment opposed to being alone with meditation. The patient was reminded that each treatment plan is personalized, to remain compliant with his medications, and continue to ask questions.

Respond and explain if you agree or disagree with how they would handle a client who was having severe anxiety. If you do not agree, please provide how they could have approached the client differently, and provide supporting rationale and citations. in 5 paragraph

Mist (airborne droplets or aerosols) is generated when metal-removing fluids are used in machining operations to cool and lubricate the tool and work-piece. Mist generation is a concern to OSHA, which has recently lowered substantially the workplace standard. The article "Variables Affecting Mist Generation from Metal Removal Fluids" (Lubrication Engr., 2002: 10-17) gave the accompanying data on x = fluid flow velocity for a 5% soluble oil (cm/sec) and y = the extent of mist droplets having diameters smaller than some value:

x: 89 177 189 354 362 442 965

y: .40 .60 .48 .66 .61 .69 .99

d. Estimate the true average change in mist associated with a 1 cm/sec increase in velocity, and do so in a way that conveys information about precision and reliability. Hint: This question is asking for a CI for beta. Compute it AND interpret it. By hand; i.e. you must use the basic formulas for the CI. E.g. for beta: beta_hat +- t* s_e/sqrt(S_xx) , but you may use R to compute the various terms in the formula. Use 95% confidence level.

e. Suppose the fluid velocity is 250 cm/sec. Compute an interval estimate of the corresponding mean y value. Use 95% confidence level. Interpret the resulting interval. By hand, as in part d.

f. Suppose the fluid velocity for a specific fluid is 250 cm/sec. Predict the y for that specific fluid in a way that conveys information about precision and reliability. Use 95% prediction level. Interpret the resulting interval. By hand, as in part d.
