Contrast osmoconformers and osmoregulators.
a) The process by which salmon maintain an internal balance is called osmoregulation. Describe how salmon achieve osmoregulation as they migrate between fresh and saltwater environments.
b) Describe what happens to salmon in fresh water. What direction do solutes tend to move via diffusion? What direction does water tend to move via osmosis?
