Question

Quizplus · Accepted Answer

The question is referring to the concept of osmosis, which involves the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. In this case, the marine vertebrate has adapted to maintain a lower concentration of solutes (such as salt) in its body compared to the surrounding seawater, in order to prevent water from leaving its cells and causing dehydration. This means that the marine vertebrate has a lower osmotic concentration than the seawater, making choice D the correct answer.

The __________ Concentration of a Marine Vertebrate Is About One-Third
