As mentioned in the video, Dr. Nachman and his colleagues have collected dark and light colored mice from dark and light colored rocks in other areas of the American Southwest and found similar patterns (i. e., dark colored mice were more likely to be found on dark rocks; light colored mice were more likely to be found on light rocks). However, genetic analysis showed that the dark fur color in other rock pocket mouse populations was caused by mutations in different genes. This means that there is more than one way (genetically speaking) to make a mouse dark. It also means that adaptive mouse coloration has occurred more than once in similar environments across the southwestern US. How does this information support the concept that natural selection is not a random process

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?
