Question

which type of solution does water move out of the cell and the cell shrinks? isotonic hypertonic hypotonic what is the main component of the cell membrane? carbohydrate cholesterol proteins phospholipids which is not a characteristic of life? must reproduce must respond to environment must sleep must be made of cells

Explanation:

1. In a hypertonic solution, the solute concentration outside the cell is higher than inside. So, water moves out of the cell by osmosis to balance the solute - solvent ratio.
2. The cell membrane is mainly composed of a phospholipid bilayer. Phospholipids have a hydrophilic head and a hydrophobic tail, which allows them to form a stable membrane structure.
3. Reproduction, response to the environment, and being made of cells are fundamental characteristics of life. While sleep is a behavior or state in some organisms, it is not a universal characteristic of all life - forms.

Answer:

1. B. Hypertonic
2. D. Phospholipids
3. C. Must sleep
