An examination of a freshwater fish that died after being placed accidentally in saltwater would likely show that ________.
A) loss of water by osmosis from cells in vital organs resulted in cell death and organ failure
B) high amounts of salt had diffused into the fish's cells, causing them to swell and lyse
C) the kidneys were not able to keep up with the water removal necessary in this hyperosmotic environment, creating an irrevocable loss of homeostasis
D) the gills became encrusted with salt, resulting in inadequate gas exchange and a resulting asphyxiation

Question

Quizplus · Accepted Answer

When a freshwater fish is placed in saltwater, there is a higher concentration of solutes outside of the fish's body than inside, leading to water loss by osmosis from cells in vital organs. This results in cell death and organ failure, ultimately leading to the fish's death. Therefore, an examination of the fish would likely reveal loss of water by osmosis from cells in vital organs resulting in cell death and organ failure.
