and size. The diagram below shows three different types of cells found in the human

body.

A. Identify one similarity, other than the genetic information, that these body cells have.

B. Explain why differences in these human body cells are a biological advantage.

Multiple Choice

Which statement describes how water is pulled up through the xylem to the leaves of the plant?

• As water exits the leaf, hydrogen bonding between water molecules pulls more water up from below.

• As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion.

• Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem.

• Evaporation of water from the leaf increases the hydrogen bonds that form between water molecules in the air, providing the energy for transport.
