  • Question 4
    60 seconds
    Q. What is cohesion?
    answer choices
    water molecules sticking to other water molecules
    water molecules sticking to different molecules
    when you dissolve a substance in a solution 
    when molecules become chemically combined
  • Question 5
    60 seconds
    Q. Why does ice float in water?
    answer choices
    Because of stronger hydrogen bonds at the surface
    The density of water as a solid is less than the density of water as a liquid
    Surface tension helps it float
    It is more dense

    answer choices
    catabolic
    anabolic
  • Question 9
    60 seconds
    Q. A chemical reaction in which a larger molecule is broken down into smaller molecules
    answer choices
    catabolic
    anabolic
  • Question 10
    60 seconds
    Q. The equations below represent two biochemical processes, A and B. 
    Equations
    (A) glucose + glucose --> maltose + water
    (B) amino acid + amino acid --> dipeptide + water

    Which statement about processes A and B is correct?
    answer choices
    Processes A and B are examples of dehydration synthesis.
    Process A is an example of hydrolysis,  but process B is an example of dehydration synthesis.
    Process B requires enzymes, but process A does not.
    Processes A and B are examples of hydrolysis.
