- PART C: CALCULATING THE DIAMETER OF THE FIELD OF VIEW (FOV)_ The field of view (FOV) is the circular area you can see when you look through the microscope. The diameter of the field of view is different depending on which objective lens you are using. For example, you are using the medium-power objective lens, then the area you can see is actually smaller than if you were using the low-power objective lens. Knowing The diameter of the field of view can help you estimate actual size of objects / cells seen through the microscope. When the revolving nose piece is turned to the low power objective lens, a dear plastic ruler can be placed on the microscope stage (see figure 1). Then, the coarse adjustment knob can be used to focus on the millimeter marks of the ruler making sure that one of the milimeter marks is at the left edge of the field of view (see figure 2). NOTE: Slage cip I-1000 Objects in the FOV are usually measured in micrometers (um). To convert, a FOV in mm, times it by 1000…Bionic Prosthetics What is the state of the technology today?Please decribe two image in complete sentences what models showns

He had just been diagnosed with acute appendicitis and was waiting to be taken to the operating room (OR). Although he desperately wanted the pain to stop, Kevin was terrified of having general anesthesia. He hoped his fear wasn’t obvious to his older brother Cole, who was finishing medical school and thought he knew everything. “Hang in there,” Cole said, for what seemed like the eighteenth time. “I’m sure they’ll get you upstairs as soon as they can. They don’t want that thing to burst.” Kevin grunted. “I know…but does that anesthesia stuff work all the time? How can I not wake up when someone’s slicing my gut open?” Cole assumed a professorial air, and Kevin wished he’d kept his mouth shut. However, Cole didn’t get a chance to say anything before an aide arrived to take Kevin to the OR. In the OR, someone placed a mask over…
