Trees utilize sunlight to synthesize (make) sugars required for life. Many trees have evolved to great heights as a result of direct competition for light. Which property of water allows trees to grow tall yet still maintain water flow to leaves?

• The cohesion behavior of water

• Water’s ability to absorb heat

• Water’s ability to dissolve nutrients

• The expansion of water upon freezing

In Florida, daytime and nighttime temperatures usually differ by 5 to 10 degrees Celsius, while temperatures in the desert often differ by as much as 40 degrees Celsius. What role does water play in keeping temperatures in Florida from fluctuating dramatically?

• Bodies of water store heat during the day and release it at night

• Humid air releases heat as it rises, keeping temperatures constant

• Evening rain brings heat from the upper atmosphere back to Earth

• Water cools the land around it so that it never gets as hot as a desert

• Ocean water is hypertonic to body tissue fluid.

• Body tissue fluid is hypertonic to ocean water.

• Ocean water is hypotonic to body tissue fluid.

• Ocean water is isotonic to body tissue fluid.

Osmosis occurs when there is a different concentration of solute molecules on each side of the membrane. The drawing below shows a beaker containing a 30% salt solution and a suspended cell containing a 10% salt solution. What statement best describes the cell after 20 minutes?

• Water will move from the cell into the beaker, resulting in a smaller cell.

• Water will move from the beaker into the cell, resulting in a larger cell.

• Salt will move from the beaker into the cell, resulting in a larger cell.

• Salt will move from the cell into the beaker, resulting in a larger cell.
