A. If you have a bucket of water, and you pour a small amount of glucose into the center, is it possible that you could come back later and find that the glucose has stayed in the center, without moving to the edge? Is it realistic? Explain why or why not. B. A cell with volume V = 9 um has a salt concentration of 1 million/um. Outside the cell, the salt concentration is 0.1 million/um?.

6. You set out to observe the behavior of carmine (red) dye by placing a small amount in a droplet of water. After some time has passed, you come back to observe the dye particles at 400X total magnification, using your super sweet microscope. a. What you observe is the following: The dye particles have dispersed throughout the water droplet and the particles appear to be moving! b. Question: What is the process responsible for your observation? Provide your answer...

Only question 5
In a bathtub, the velocity of water near2 the drain is given by the vector field (22 +1)2222 + 1 where r, y, and z are measured in centimeters and (0, 0,0) is at the center of the drain. 1. Rewriting F as follows, describe in words how the water is moving: Consider each of the three terms in equation (4). (Look at some plots.) For fixed z, what is the flow like? How...

There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin off the water. The radius of the container is 14.4 cm. When the cylinder is rotating at 1.09 revolutions per...
