Which of the following best describes the role water plays in passive transport?

• Water regulates temperatures within the cell.

• Water assists in the digestion of cellular compounds.

• Water carries molecules across membranes during diffusion.

• Water collects in the soft tissue of plant cells making them more rigid.

Hydrogen bonding- (check all that apply)

• causes cohesion

• causes adhesion

• causes polarity

•  

  is the cause of water's high boiling point

Which property of water makes it well suited for the transport of gases and electrolytes through the human body?

• Its low molecular weight makes it an easy substance to pump.

• Its high polarity makes it an excellent solvent of many substances.

• Its high specific heat makes it resistant to temperature change.

• Its relative chemical stability makes it an excellent energy source.

Which property of water is responsible for the phenomena observed in this photo?

Which statement best describes what is occurring when NaCl dissociates in water?

• hydrogen atoms create repulsive forces with sodium and chloride ions

• the partial negative charge created by the oxygen atom in water is attracted to the positive sodium ion

• gravity rotates the water molecules so that oxygen faces outward

• the hydrogen bonds between the water molecules undergo a combustion reaction with the NaCl
