For what kind of external environment is a saltwater fish adapted?(1 point) Responses hypertonic environment hypertonic environment isotonic environment isotonic environment hypotonic environment hypotonic environment osmotonic environment

Answer 1

A saltwater fish is adapted to a hypertonic environment. In this context, the surrounding water has a higher concentration of salts than the fish's internal body fluids, which leads to the need for these fish to actively regulate their internal osmotic balance.
