Draw the interference pattern for a double-slit interference situation on a screen. Label the constructive and destructive interference regions clearly with words and show the representation clearly. Indicate where the central maximum is.
If a pane of glass is inserted in the gap between the slits and screen, what is the effect on the interference pattern? Draw the new pattern next to the original and explain any changes in the positionings of the pattern. Use words to explain as well as equations.

There are only a handful of signaling pathways (FGF, WNT, BMP/TGFB, HH, Notch, steroid) that shape development. Which one do you think is the most important? Sketch the signaling pathway (ligand, receptor, intercellular signaling). Defend the importance of your choice with specific examples. Identify a human disease caused by changes in this signaling pathway. Propose a way to treat the condition by modulating the pathway with genetic technology.

Hemoglobin is the main protein in red blood cells and performs
the function of transporting oxygen. Oxygen is combined into the
hemoglobin's prostatic group, heme molecule.
A. Describe the changes in the quadratic structure of hemoglobin
with oxygen binding and explain the role of the 2,3-BPG.
B. Describe the reasons for oxygen deficiency in the highlands and
the body's action in adapting to high-altitude hypoxic
environments.
C. Describe the bohr effect that affects the oxygenation of
hemoglobin.

it takes careful analysis to determine the actual cause and effect of a breakdown / problem. Although many of you have taken statistics courses by now, I find that many students are not confident with their analytical skills. These are important skills to develop and your abilities and confidence will improve with experience. Many students are able to do the mathematical analysis, but cannot put the results into practical application. What changes does your analysis suggest?

1)If, for a given conductor, the local surface charge density is sigma, what is the direction and magnitude of the electric field in that region? 2)What’s the value of the electric field inside a conductor and why? 3)Where is the excess stationary electric charge located for a conductor and why? 4)What is a Gaussian surface? 5)If you increase/decrease the area of a Gaussian surface, how does the net flux through it changes?

Discussion Topic: Distinguish between common vision problems in the older adult (Age-related macular degeneration, cataracts, diabetic retinopathy, and glaucoma). What is the clinical presentation, risk factors, and treatment for each? Discuss the impact these vision changes have on functional abilities. What pharmacologic and non-pharmacologic interventions should be included in the plan of care of the client with the vision problem? What patient and family teaching should be included?

- Activity-Based Costing Define activity-based costing (ABC) systems. What benefits does implementing an ABC system bring to the company? Explain at least two benefits. What are the disadvantages to implementing an ABC system? List and explain at least two. Would the proposed changes make ABC a universally applicable costing method in your opinion? Why or why not? Elaborate your response.
No plagiarised answer, please.

A golf ball strikes a hard, smooth floor at an angle of 35.0 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0542 kg, and its speed is 41.0 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the weight of the ball.)
