Peas heterozygous for three independently assorting genes were intercrossed.

(example cross: Aa Bb Cc x Aa Bb Cc )

What proportion of the offspring will be homozygous for one gene and heterozygous for the other two?

(hint: apply binomial expansion equation)

1/4

3/8

1/8

3/16

already answered 1/4 and 1/2 and they were incorrect

Two identical point charges (q = +5.80 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.320 m. A test charge (q0 = -7.90 x 10-8 C), with a mass of 6.20 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square.

chief Complaint: 40-year-old man with a cough and dyspnea. History: Joe Butt, a 40-year-old white male with a 52-pack-year smoking history suffered from chronic bronchitis. For the last several months he has been on an antibiotics treatment. Three weeks ago, his otherwise normal smoker’s cough started producing bloody sputum ("hemoptysis"). In the past week Joe has become increasingly short of breath ("dyspnea"). A routine chest X-ray revealed a couple of quarter-sized opacities in his right lung around the alveoli. Bronchoscopic examination revealed the tumors were nearly occluding two major bronchioles in his right lung. A bronchial biopsy revealed the diagnosis: bronchogenic carcinoma. Questions: 1. What is "bronchogenic carcinoma"? What medical professional most likely confirmed the nature of the biopsy? 2. Describe the structure of the bronchial epithelium. How many layers of cells make up this tissue? 3. Describe what the “mucociliary escalator" is and it’s function in the respiratory system. 4. What two conditions do you think have led to Joe experiencing a shortness of breath ("dyspnea")? 5. What is the most likely or common way that this type of cancer may metastasize (i.e. spreading to other parts of the body)?

A certain production process employs two inputs¾labor (L) and raw materials (R).  Output (Q) is a function of these two inputs and is given by the following relationship:

                           Q = 6L² R² - 0.1L3 R³

Assume that raw materials (input R) are fixed at 10 units

5 - Find the number of units of input L that maximizes the marginal product function

6 - Find the number of units of input L that maximizes the average product function

7 - Determine the boundaries for the three stages of production

8 - Find the number of units of input L where the law of Diminishing Marginal Returns starts to take effect first

True/False Questions.

For each question below, please answer “true” or “false” and explain why.

6. A consumer with convex preferences who is indifferent between the bundles (5,2) and (11,6) will like the bundle (8,4) at least as well as either of the first two bundles. Assume these two goods are imperfect substitutes.

7. The marginal rate of substitution is always the same constant number when the goods are imperfect substitutes and no matter how many of each good is being consumed.

8. The transformation of a utility function described as f(u) = ln⁡ (α(U(x,y))) where α=-1 will retain the ordinal preferences of bundle A preferred to bundle B.

Python Programming

1. Write a function name split_name which takes one parameter called name. If the name parameter value is a name in the form LastName, FirstName(e.g., ”Grounds, Nic”) then the function should return a list of two elements where FirstName is the first element and LastName is the second element. If the name parameter value is a name in the form FirstName LastName(e.g., ”Nic Grounds”) then the function should return a list of two elements where FirstName is the first element and LastName is the second element.

2. Repeatedly prompt the user for a name (which the user may give in Last-name, FirstName form or FirstName LastName form). If the user’s response is an empty string (i.e., they simply press Return) cease looping. If the user’s response is not the empty string, call the split_name function you wrote and append the returned value to a list (initially empty).

3. Using the sorted function (which can take a single parameter, a list) and returns a copy of the list in sorted order) sort the list of names once the loop has finished. Print the sorted list of names, one name per line in LastName, FirstName form.

4. Observe the sorted list of names, are they sorted alphabetically by first name or last name? Leave your answer in a comment within the Python file you submit. Also, how do you think we could potentially modify the program to sort by last name instead of first (or first name instead of last, whichever is opposite of what you observed)? Leave your answer in a comment within the Python file you submit.

5. At the top of your file must be a comment that contains a brief explanation of how you determined which portion of each name was the first name vs. the last name.

Buchholz Corporation follows a moderate current asset investment policy, but is now considering a change, perhaps to a restricted or maybe to a relaxed policy. The firm's annual sales are $400,000; its fixed assets are $100,000; its target capital structure calls for 50% debt and 50% equity; its EBIT is $50,000; the interest rate on debt is 8%; and its tax rate is 25%. With a restricted policy, current assets will be 15% of sales, while under a relaxed policy, current assets will be 25% of sales. What is the difference in the projected ROEs between the restricted and relaxed policies? Enter your answer rounded to two decimal places. Do not enter % in the answer box. For example, if your answer is 0.12345 or 12.345% then enter as 12.35 in the answer box.

We have a bag filled with 201 marbles, of which 100 of them are blue and 101 of them are red. Every turn, we remove 2 marbles from the bag. If the two marbles are of the same color, we remove the two marbles but add a blue marble into the bag. If the two marbles are of different colors, we remove the two marbles and add a red marble into the bag. What is the color of the last marble in the bag?
