Study this photo below carefully.  It shows a microscopic image collected during a urinalysis.  It was acquired with a compound microscope set at 400x total magnification.  Imagine that you are tasked with interpreting the results of such a test and must make a preliminary diagnosis.  In 1-2 complete sentences, FIRST identify the most likely diagnosis that you would assign to this case, based ONLY on the sediments you see in this image.   Be as specific as you can with this diagnosis (i.e., you can’t just say “kidney disease” and call it a day).  NEXT, explain your reasons for making this specific diagnosis by describing at least TWO abnormalities that you see here.

You review the food label and find the nutritional adequacy statement. What method does this food manufacturer use to verify nutritional adequacy? Image states under Complete & Balanced: Nature’s Variety Instinct Raw Small Breed Chicken Formula provides complete and balanced nutrition for dogs of all life stages and is comparable in nutritional adequacy to a product which has been substantiated using AAFCO feeding tests.

Use the pull-down menus to insert the best terms that make these sentence true: Even if you are stranded on a desert island with no water intake, you will still [blank1] approximately [blank2] of urine per day to remove nitrogenous wastes and any excess biomolecules and ions from your body.  This minimum amount of urine is called [blank3].

Study this composite diagram showing microscopic images of the events that occur after fertilization.   Use the pull-down menus below to answer each question:

A company has bonds outstanding with coupon rate equal to 8%, semi-annual interest payments and 10 years remaining until maturity.  The current price of the bond is $1,109.16 and face value is $1,000.  The tax rate is 30%.  Calculate the component cost of debt (i.e. amount that debt contributes to the WACC). 

A company’s preferred stock is currently trading at $26.80.  The par value is $25 and dividend rate is 6%. If the company issued additional preferred stock they would incur a flotation cost of 5%.  Calculate the marginal cost of new preferred stock (rps). 

Laverne is visiting her best friend Shirley in Milwaukee.  Fun fact … Milwaukee derives from the Algonquin word “millioke”, meaning “the good land.”  Anywho … Shirley was recently diagnosed with metabolic syndrome and needs to monitor her blood glucose levels closely.  Being about the same age, Laverne becomes curious about her own blood sugar levels, so she tests herself with Shirley’s glucometer.  The meter indicates that Laverne’s blood glucose level is currently 120 mg/dL. Given this abnormal reading, describe the steps of the negative feedback loop that Laverne’s body will use to solve this problem and return her to homeostasis in the space below.  You may use any appropriate Effector that you prefer to tell this story.  Assume that Laverne has no metabolic diseases of her own and is perfectly healthy in all respects.  You may list the generic steps and give a brief description of each step, like this: 1) Stimulus – type your description 2) Sensor – type your description etc., etc., until you arrive at the desired Response Make sure to list all the generic steps of a feedback loop for this class AND describe the specific physiological details for each of those steps EXACTLY as if you were drawing a feedback loop diagram like we did during these last 4 labs.  Provide as much physiological detail as possible at each step (e.g., effector cells, receptor types, signal molecules, the step-by-step “action” that fixes the problem, etc.).

When the membrane of the sperm and egg fuse, the plasma membrane of egg cell will  _______.  This event quickly prevents other sperm cells from penetrating the oocyte.

A mining project has an initial cost of $900.  The expected cash flows for the following 5 years are given in the following table:   The project’s weighted average cost of capital (WACC) is 10%.  Calculate the modified internal rate of return.
