16. A student is using a straw to blow bubbles into a calcium hydroxide solution. The carbon dioxide in the student's breath is reacting with the water to form an acid, which
begins to neutralize the basic solution. Which of the following best describes the initial
change in pH of the solution?
A. increase in pH toward a pH of 7
B. increase in pH away from a pH of 7
C. decrease in pH toward a pH of 7
D. decrease in pH away from a pH of 7

but there is no

i guess you forgot putting it.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
