7. How does AZT block the production of infectious virus?
It acts as a substitute for a DNA nucleotide that can only be inserted by the viral reverse transcriptase. The presence of the AZT in the DNA aborts the production of new viral DNA.
It directly blocks the reverse transcriptase.
It blocks the protease that cuts apart the three viral proteins, which is a necessary step during viral synthesis.
It blocks the adsorption of the virus to the CXCR4 and CCR5 receptors on the T-cell surface.

Assignment Question(s): (Marks 5)
Q1. Alfa Company is issuing eight-year bonds with a coupon rate of 6.5 percent and semiannual coupon payments. If the current market rate for similar bonds is 8 percent, what will be the bond price? If the company wants to raise $1.25 million, how many bonds does the firm have to sell?
1 mark
Q2. Suppose a 3 year bond with a 6% coupon rate that was purchased for $760 and had a promised yield of 8%. Suppose that interest rates increased and the price of the bond declined. Displeased, you sold the bond for 798.8 after having owned it for 1 year. What is the realized yield ? 1 mark

Deepwater Horizon Rig Disaster Threatens Drilling
British Petroleum (BP) is an oil exploration and production company that encourages high risk projects with the potential for high return. Last summer the company’s exploration and production chief, Andy Inglis, is quoted as saying, “We don’t do simple things. We are prepared to work on the frontier and manage the risks.” So far that strategy has paid off for BP. Now that strategic decision is being called into question.
BP’s earnings for the quarter ending March 31, 2010 were $5.6 billion; more than double what they were five years ago. However, a recent deepwater drilling rig accident in the Gulf of Mexico killed eleven employees and has spewed over three million barrels of oil into the ocean with no real end in sight. The company’s disaster is threatening one of the most productive fisheries in the world and the fragile Gulf ecosystem.
From BP’s perspective the disaster may also be threatening the company’s future. If the spill is not contained soon it may mark the end of Gulf exploration and drilling. The practice may be deemed too risky, both politically and environmentally. For a company that has staked much of its future on the Gulf, it may also signal the end of BP. Investors are abandoning BP and the company has lost over $30 billion in market capitalization since the disaster.

Assignment: Regulation for Nursing Practice Staff Development Meeting
Nursing is a very highly regulated profession. There are over 100 boards of nursing and national nursing associations throughout the United States and its territories. Their existence helps regulate, inform, and promote the nursing profession. With such numbers, it can be difficult to distinguish between BONs and nursing associations, and overwhelming to consider various benefits and options offered by each.
Both boards of nursing and national nursing associations have significant impacts on the nurse practitioner profession and scope of practice. Understanding these differences helps lend credence to your expertise as a professional. In this Assignment, you will practice the application of such expertise by communicating a comparison of boards of nursing and professional nurse associations. You will also share an analysis of your state board of nursing.

Nursing Essay HelpFlowering plants
Nursing HomeworksAngiosperms (flowering plants) are the largest Phylum in the plant kingdom Plantae. These plants have true roots, stems, leaves, and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as the main organs for photosynthesis. Stems provide above-ground support for the plant and operate as conduits to move nutrients and water throughout the plant. Flowers contain the male and female reproductive organs of the plant.
Plants develop specialized roots, stems, leaves, and flowers to make them better adapted to their environment. With the anatomical features described above in mind, do some research to find an angiosperm that has modified leaves, stems, roots or flowers that are structurally different from the norm, do not function in the normal manner, or that function in an unusual manner. For example, a cactus has spines in place of leaves. The spines help reduce water loss that would occur through a large, expanded leaf in a desert environment, and they also help to prevent herbivory.
