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

Answer 1

A saltwater fish is adapted to a hypertonic environment. In this type of environment, the salt concentration outside the fish is higher than inside its body, which presents challenges for maintaining osmoregulation. Saltwater fish must actively retain water and excrete excess salt to survive in such conditions.
