Complete the following dihybrid crosses. Draw out the Punnett for the F₁ generation and the F₂ generation.

1. In Drosophila, fruit flies, individuals with ebony body color and vestigial (small) wings represent the homozygous recessive. If you crossed an individual that was homozygous dominant (normal) for both genes with an individual that was homozygous recessive for both genes, you would observe the following:

a. phenotypic ratio in the F₁

b. phenotypic ratio in the F₂

c. genotypic ratio in the F₁

d. genotypic ratio in the F₂

1) At 25

ArrayStack:

package stacks;
public class ArrayStack<E> implements Stack<E>
{
   public static final int CAPACITY = 1000; // Default stack capacity.
   private E[] data; //Generic array for stack storage.
   private int top = -1; //Index to top of stack./*** Constructors ***/
   public ArrayStack()
   {
       this(CAPACITY);
       }
   //Default constructor
   public ArrayStack(int capacity)
   {
       // Constructor that takes intparameter.
       data = (E[]) new Object[capacity];
       }
   /*** Required methods from interface ***/
   public int size()
   {
       return (top + 1);
       }
   public boolean isEmpty()
   {
       return (top == -1);
       }
   public void push(E e) throws IllegalStateException
   {
       if(size() == data.length)
       {
           throw new IllegalStateException("Stack is full!");
           }
       data[++top] = e;
       }
   public E top()
   {
       if(isEmpty())
       {
           return null;
           }
       return data[top];
       }
   public E pop()
   {
       if(isEmpty())
       {
           return null;
           }
       E answer = data[top];
       data[top] = null;
       top--;
return answer; }
}

Recall: In the array based implementation of the stack data type, the stack has a limited capacity due to the fact that the length of the underlying array cannot be changed. In this implementation, when a push operation is called on a full stack then an error is returned and the operation fails. There are certain applications where this is not useful. For example, a stack is often used to implement the \undo" feature of text editors, or the \back" button in a web browser. In these cases, it makes sense to remove the oldest element in the stack to make room for new elements. A similar data structure, called a leaky stack is designed to handle the above type of situation in a dierent manner. A leaky stack is implemented with an array as its underlying storage. When a push operation is performed on a full leaky stack, however, the oldest element in the stack is \leaked" or removed out the bottom to make room for the new element being pushed. In every other case, a leaky stack behaves the same as a normal stack. Write an implementation of the leaky stack data structure. Your class should be generic and implement the following public methods: push, pop, size, and isEmpty. Your class must also contain at least two constructors: one where the user does not specify a capacity and a default capacity of 1000 is used, and one where the user does specify a capacity.

Hint: The following is a skeleton of the class to get started (You will have to fill in the missing implementations of the abstract methods from the Stack interface):

public class LeakyStack implements Stack {

public static final int DEFAULT = 1000;

private E[] stack; private int size = 0;

private int stackTop = -1;

public LeakyStack()

{

this(DEFAULT);

}

public LeakyStack(int c);

public void push(E e);

public E pop();

public boolean isEmpty();

public int size(); }

Make sure you articulate some of the ethical issues you discover in commercials that target children.

Consider the titration of a 20.0mL sample of 0.105M HC2H3O2 with 0.125M NaOH. Determine each of the following. a) Initial pH b) the volume of added base required to reach the equivelence point c) the pH at 5.0 mL of added base d) the pH at one-half of the equivelence point e) the pH at the equivelence point f) ph after adding 5.0ml of base beyond the equivalence point

• Opportunity A: a "me-too" oncology drug currently in Phase 3 clinical trials that requires a $100 million investment today (year 0), and if successful, provides annual profits of $100 million over its remaining 10 year patent starting in year 3 (otherwise it returns nothing). Suppose the probability of success is 50%.
• Opportunity B: a combination therapy of blinatumomab and chemotherapy designed to cure acute lymphoblastic leukemia that requires a $200 million investment today (year 0), and if successful, provides annual profits of $2 billion over its remaining 10 year patent starting in year 11 (otherwise it returns nothing). Suppose the probability of success is 5%.

A) What are the expected annual cash flows of opportunity A for years 3 to 12? (Note: Your answer should be expressed in units of millions of dollars.)

Expected annual cash flow = $___ million

B) What are the expected cash flows of opportunity B for years 11 to 20? (Note: Your answer should be expressed in units of millions of dollars.)

Expected annual cash flow = $____ million

C) Suppose we calculate the NPV of each opportunity by discounting the expected cash flows. Assume a discount rate of 12% per year for opportunity A, and 20% per year for opportunity B. What is the NPV of each opportunity? (Note: Your answer should be expressed in units of millions of dollars.)

NPV opportunity A = $____ million

NPV opportunity B = $____ million

Add up the total grams of organic material extracted via 3 extractions and compare it to the grams extracted with only 1 extraction. What conclusions can you make about the use of multiple extractions?

2.Some tumor suppressor genes inactivated during multi-step tumorigenesis may be readily identified because of LOH in the chromosomal region carrying them, while others may be difficult to identify in this way. Describe the factors that allow or complicate this identification.

During the course, you have designed a network to meet the specific needs of your client. Now, it is time to showcase that design. When you are dealing with a client, communication plays a key role in your professional success. You may have a very effective design, but you may not still be able to achieve maximum client satisfaction if you cannot communicate your design to your client properly.
For this part of the Final Project, review this week’s resources. Give special attention to the resource “Oral Presentation and PowerPoint.” Remember the following when developing the presentation:

Keep the presentation short and simple.

Do not load the presentation down with paragraphs of text. Keep it simple and use images.

Make sure that the presentation is informative and that it uses facts and figures.

When presenting to a non-technical audience, try to refrain from making it too technical. Remember that the presentation would normally be presented to leadership who most likely will not understand the technical information.

Explain clearly to the leadership the costs and benefits that the network will offer to the organization.

Presentation (6–10 slides):
Create a PowerPoint presentation with a narrative overlay. The overall slide show must be in the 8–10 minute range. The presentation must be engaging, organized, easy to understand, appropriate for the intended audience, and complete the following:

Introduce the presentation

Describe the network in layman’s terms

Identify how the network meets each specific client need

Describe how the network ensures security

Provide technical details with which the client needs to be familiar

Instruct the client on any technical needs for supporting the network

Summarize the presentation

Note: To complete this presentation, you must have Microsoft PowerPoint 2007 or a higher version loaded on your computer. In addition, you must have a microphone to record your oral narrative to accompany the presentation.
Once the PowerPoint slides are complete, you have created a written copy of the narrative, and you have tested the narrative to be sure it is the proper overall length (time), you will embed the oral narrative into the file. To embed the narrative, complete the following steps.
Beginning with the first slide:

Select the Slide Show Tab—Record Narration—Set microphone level.

Talk into your microphone to make sure it is working properly.

Click OK—Begin your narrative for the first slide.

Advance to the next slide (left click)—Be sure you are done speaking before you left click.

Record the narrative for the second slide.

Continue advancing through the slides and recording your narrative.

After the last slide, you will be asked if you want to save the slide timings—Select SAVE.

Now start your slide show. The show will progress at the pace you set while creating the narrative for each slide.

If you need to redo the recording, simply go back to the first slide. Then, select the Slide Show Tab and re-record your narrative, or you may choose to re-record just one slide at a time.

REPEAT steps 1–8 until you are satisfied with the presentation and your slide show is completed in 6–10 minutes.

Save the PowerPoint presentation with embedded narrative.
Submit your Final Project Part 5 through uploading your file (saving it according to the filenaming convention specified in this Assignment’s submission link) by Day 5.
