Question
Why do freshwater vertebrates have to actively transport inorganic ions in their bodies?Multiple choice question.Because they are hypertonic to the environment and tend to lose ions.Because most freshwater vertebrates accumulate ions throughout their life.Because freshwater vertebrates require high concentrations of inorganic ions from their kidneys to work.Because they are hypotonic to the environment and tend to lose ions.
Solution
The correct answer is: Because they are hypotonic to the environment and tend to lose ions.
Freshwater vertebrates are hypotonic to their environment, meaning their bodily fluids have a lower concentration of solutes (like inorganic ions) than the freshwater environment. This causes water to move into their bodies by osmosis, while ions tend to diffuse out. To maintain their bodily functions and prevent ion deficiency, these vertebrates need to actively transport inorganic ions back into their bodies against the concentration gradient. This is done through various ion transport mechanisms in their gills, skin, and kidneys.
