Coherent light with wavelength 450 nm is incident upon a pair of slits. The interference pattern produced on a screen 2.0 m from the slits is measured to have a separation between two adjacent bright fringes of 1.8 mm. Next, a laser with an unknown wavelength shines upon these same pair of slits and screen. The interference pattern shows the distance between adjacent bright fringes is 0.5mm. What is the wavelength of this mystery laser, in nm?

The client was given Morphine 2mg IV for pain associated with a right fractured rib 1 hour ago and now has the following vital signs: B/P 100/56 mmHg, Pulse 110, RR 14, SPO2=91% on room air, and Temp 38.1 Celsius.  The client is laying on their left side and is sleepy . Which of the following priority interventions will the nurse complete first?  

Use the following description to answer the question(s) below.In the ocean, on either side of the Isthmus of Panama, are thirty species of snapping shrimp; some are shallow-water species, others are adapted to deep water. There are fifteen species on the Pacific side and fifteen different species on the Atlantic side. The Isthmus of Panama started rising about ten million years ago. The oceans were completely separated by the isthmus about three million years ago.In the following figure, the isthmus separates the Pacific Ocean on the left (side A) from the Atlantic Ocean on the right (side B). The seawater on either side of the isthmus is separated into five depth habitats (1-5), with 1 being the shallowest.Which factor is most important for explaining why there are equal numbers of snapping shrimp species on either side of the isthmus?

Which of the following information or processes does gene therapy require?
