Grade 9 Biochemistry
The picture below shows a group of water skate bugs “walking” on the surface of a pond. When an insect lands or falls into the water, the water molecules vibrate. The water skater uses the resulting vibrations to find its prey. What property of water enables this bug to stay on the surface of the pond and not sink?
  1. Water’s high specific heat enhances the vibrations causing the bugs to float.
  2. An optimum pH of the pond water keeps the water calm so that the bugs don’t sink.
  3. The hydrogen atoms, in the water, bond to the bugs’ legs keeping the bugs on the surface.
  4. Hydrogen bonds provide cohesion of the water molecules enabling the bugs to stay afloat.
Grade 8 Biochemical Pathways

  1. water [math](H_2O)[/math] and glucose [math](C_6H_12O_6)[/math]
  2. glucose [math](C_6H_12O_6)[/math] and carbon dioxide [math](CO_2)[/math]
  3. carbon dioxide [math](CO_2)[/math] and water [math](H_2O)[/math]
  4. glucose [math](C_6H_12O_6)[/math] and oxygen [math](O_2)[/math]
Grade 8 Biochemical Pathways
