[0] Draw a class hierarchy for the classes defined above.

[1] No or Yes:  class R extends Object

[2] class G extends C   does not compile. Why?

[5] System.out.println(new R());   prints: R@6bc7c054   Why?

[6] No or Yes:  class D can have subclasses (children).

[7] If  public String toString() { return "Arizona"; }  
    is added to class A, then System.out.println(new D()); 
    prints what?

[8] Assume the following is added to class C.

    public String toString() { 
       int azAgeIn2018 = 2018 - 1912;
       return "Arizona is " + azAgeIn2018 + " years young!";
    }

    What does System.out.println(new C()); print?

[9] System.out.println(new R().hashCode());  prints: 1808253012.
    No  public int hashCode()  method is implemented in class R.
    Briefly explain why this compiles and runs?

[10] If  public int hashCode() { return 48; }  is added to 
     class R, then what does the following statement print?

     System.out.println("Arizona is state# " + new R().hashCode());

Description

Mr. Bryan is a 29-year-old married man who came to the medical office because, over the last three years, he has progressively increased the size of his shoes, and he has resized his wedding ring three times. He says his feet and hands have grown. He has also noticed that his face has turned coarse. He was a very active man and practiced sports, but now he fatigues just by walking, and feels weakness in his muscles and stiffness in his joints. He is depressed because in the last few months he has been experiencing erectile dysfunction, which is affecting his relationship with his wife. He feels he is losing his vision as well.

Mr. Bryan does not drink alcohol, smoke, or use any recreational drug. His mother suffers from diabetes mellitus type II, and his father suffers from hypertension.

On physical examination we found:

Remarkable Signs

• Head: Enlarged and coarsened facial features, prominent superciliary arches, prognathism
• Neck: Thyroid is visible and palpable
• Thorax: Barrel appearance
• Abdomen: Hepatomegaly. Splenomegaly.
• SOMA: Enlargement of the hands and feet. Generalized arthralgia.

Remarkable Signs

• Integumentary system: Thick and oily skin. Numerous acrochordon disseminated throughout the body.
• Cardiovascular system: Blood pressure 150/100. Radial pulse 72.
• Digestive system: Megaloglossia. Diastema.

provided, respond to the following questions:

1. The patient refers to muscle weakness. Mention some common muscular diseases, and explain them briefly, including their prognoses.
2. Is Mr. Bryan at risk of suffering from diabetes mellitus? Why? How many types of diabetes mellitus are there? What are the differences between them?

Shelley believes that the unit sales, variable costs and equipment cost projections are accurate to ±20%.

Taxpayer is considering the following investment.

Compute the present value of the after-tax cash flows of this investment, using a discount rate of 6%. Note: This investment begins with year 1, not year 0. Your cash flows should be discounted accordingly.

1. What is countercurrent exchange? Give an invertebrate example, both naming the taxon and explaining how it works and what it achieves. Use a simple figure with labels as well as some text (in your own words, of course) to explain.
2. What is a coelom and what advantages does it provide in animals that have it? Name some phyla that have and do not have a full coelom. How is the status of having or not having a full coelom predicted to affect invertebrate design and function, including movement?
3. Give some examples of colonial animals where the individual units within a colony are specialized for different functions. What are the functions? What colonial animals do not show specialization within a colony, i.e., all the units are instead functionally equivalent. Be sure to consider this question at the level of phyla and do discuss ALL of the colonial phyla that we have discussed in this course. Note if all the members of the phylum share the features you mention or only a subset.
4. Describe the difference between ocelli and image-forming eyes. Give examples of phyla that have both types of light sensing abilities across different species within a phylum.

The business I am opening is Spirulina. Spirulina is a micro-algae and as such has been growing naturally in our environment for millions of years, it is a tough plant able to withstand harsh growing conditions, in fact, the micro-algae cell never really dies it goes dormant when weather conditions are not favorable, and as soon as these change and the environment is once again suitable for growth, spirulina begins growing and reproducing again. Naturally growing spirulina can be found in high alkaline lakes and in general, it is said that where flamingos are, spirulina is sure to be found. It is a type of cyanobacteria, which is a family of single-celled microbes that are often referred to as blue-green algae. Just like plants, cyanobacteria can produce energy from sunlight via a process called photosynthesis (Ebène, 2011-2016). The main reason that I am interested in such a product is that the product benefits people’s health which I am going to mention and cover in the rest of my report.

Question

Using your Business idea. Create a sample cashflow sheet that would be specific to your business. You can create a monthly statement that will culminate to an annual total.

A 30 y male was delivered to andrology department for medical evaluation due to ineffective sexual competency. His physical examination and interview with the specialized physician revealed some other symptoms that were related to wounds that won’t heal, unexplained weight loss, hair loss, lack of alertness and sometimes diarrhea. These symptoms were seen in the last 6 months only and nothing seen before. Semen analysis and other tests were prescribed and the results were: Semen analysis Days of abstinence: 3 days Time of collection: 9:30 am Time of receipt: 9:45 am Liquifaction time: 30 min Volume: 4ml Viscosity: normal pH: 8.5 Sperm concentration: 12 million/ml Sperm motility: marked decreased motility Morphology: more than 50% normal forms Spermatids and WBCs: less than 1 million/ml Other tests Fructose level was in normal range Viability testing showed that most sperm are viable Low serum testosterone Discuss these results, what is the expected case, mention any confirmatory tests if required?

You cringe, want to pull your hair out and strongly desire to open handedly slap your good friend Ima Nodall when you hear her explaining to her sister that; "spermatogenesis and oogenesis are exactly the same process - one just has a tail, the other doesn't.'' While you secretly bristle at the thought of this misinformation, you decide that you will lay out a point by point essay comparing the two processes. In this essay, you should really let Ima know that she does have a point, there are some similarities in the processes (1 pt per similarity, mention at least two (2 pts total)) but largely the processes are different. These differences should include differences in timing including when in a person’s lifetime the processes are active (2 pts), how many gametes are produced with each process (include viability of cells) (4 pts) and the actions of FSH and LH (include 1 function per hormone for each process) (8 points). After gametes are produced where do they mature(2pts) 2 pts for essay formatting, grammar, spelling.

5. What is the functiion of the sarcoplasmic reticulum in muscle cell contraction?

6. Explain why calcium ions and ACh are vitals for muscle contraction.
