Which type of environment results from an equal amount of solute and solvent in and out of the cell?
a. hypertonic environment
b. isotonic environment
c. hypotonic environment
d. flaccid

a molecule that moves across a cell membrane without using the cell's energy tends to move
a. away from the area of equilibrium.
b. away from the area where it is less concentrated.
c. away from the area where it is more concentrated.
d. toward the area where it is more concentrated.

The correct answer for first question is- B) Isotonic enviroment.

Isotonic environment is created in and outside a cell when the concentration of solute ( like salt) and solvent ( like water) are same on both the sides ( that is inside and outside the cell).

In other words, it represents the same osmolarity.

The correct answer for second question is- C) Away from the area where it is more concentrated.

When a molecule moves across a cell membrane without using energy, it represents passive transport. In this transport, molecules move from an area where their concentration is high to an area of lower concenteration.

Thus, option C) is the right answer.

dang that balls went far

what is the actual question though?
