Question

1. which statement below best describes how a cell responds to its external environment? a. the difference in concentration of solids in a cells external environment has no effect on how water moves into and out of a cell. b. if the concentration of solids in the cells external environment is greater than the internal environment, water passes out of the cell. c. if the concentration of solids in the cells external environment is less than the internal environment, the water passes out of the cell. 5. conclusion: the dialysis tubing in the beakers represented cells in solution. which beaker represented which type of solution? isotonic: type answer here hypertonic: type answer here hypotonic: type answer here

Explanation:

For question 4, osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. If the external environment has a higher solute concentration (hypertonic), water moves out of the cell. For question 5, in an isotonic solution, there is no net movement of water; in a hypertonic solution, water moves out of the cell; in a hypotonic solution, water moves into the cell. But without information about the beakers, we can only define the solutions conceptually.

Answer:

1. B. If the concentration of solids in the cell’s external environment is greater than the internal environment, water passes out of the cell.
2. Isotonic: A solution where the solute concentration is equal inside and outside the cell, resulting in no net water movement.

Hypertonic: A solution where the solute concentration outside the cell is higher than inside, causing water to move out of the cell.
Hypotonic: A solution where the solute concentration outside the cell is lower than inside, causing water to move into the cell.
