What does it mean for an environment to be isotonic?(1 point) Responses The concentration of solute in the environment is different from the concentration inside the cell. The concentration of solute in the environment is different from the concentration inside the cell. The concentration of solute is greater in the environment than inside the cell. The concentration of solute is greater in the environment than inside the cell. The concentration of solute is greater inside the cell than in the environment. The concentration of solute is greater inside the cell than in the environment. The concentration of solute in the environment and the concentration inside the cell are at equilibrium.
The concentration of solute in the environment and the concentration inside the cell are at equilibrium.
For an environment to be isotonic, the concentration of solute in the environment is the same as the concentration inside the cell.
To determine what it means for an environment to be isotonic, we need to understand the concept of concentration of solute. In biology, cells are surrounded by a fluid environment called the extracellular fluid. This fluid contains various substances, including solutes like ions and molecules.
Isotonic refers to a specific concentration relationship between the solute concentration inside the cell and the solute concentration in the environment. It means that the concentration of solutes is the same inside the cell and in the surrounding environment.
In the given options, the correct response would be: "The concentration of solute in the environment and the concentration inside the cell are at equilibrium." This means that there is no net movement of water across the cell membrane, as the concentration of solutes is balanced both inside and outside the cell.
