Question

an investigation was designed to determine how freshwater fish maintain homeostasis within their environment. it was observed that the concentration of substances inside the fish cells was much higher than the concentration of substances in ponds, lakes, and streams and that freshwater fish have a constant flow of water from the environment into their cells. based on these observations, in what type of environment must these fish live?

oa hypertonic

ob hypotonic

oc isotonic

od osmotic

Explanation:

In a hypotonic environment, the solute concentration outside the cell is lower than inside the cell. Water moves into the cell by osmosis. Since freshwater fish have a higher concentration of substances inside their cells compared to the surrounding water in ponds, lakes, and streams and there is a constant flow of water into their cells, they live in a hypotonic environment.

Answer:

B. hypotonic
