  • 1

    It is one of the most plentiful compounds on Earth, referred to as an inert space filler in a living organism.

    water

  • 2

    Water is a major component of the cell, making up this percentage of its weight.

    70-90%

  • 3

    How long can a person live without water?

    3 days

  • 4

    death

  • 5

    These are the four properties of water.

    solvent, transporter, temperature regulator, lubricant

  • 6

    Water dissolves, not only “like” polar substances but many non-polar substances as well. This is why water is known to be a

    universal solvent

  • 7

    This is a reaction that happens when large compounds are broken down into smaller compounds by adding water.

  • 8

  • 11

    Why does water take a great deal of heat to turn into water vapor?

    heat retention

  • 12

    Even when temperatures are not very hot, water is constantly evaporating from the skin and lungs, making our body temperature remain constant. This water loss is called

    insensible perspiration

  • 13

    This body fluid helps joints such as knees and elbows to move easily.

  • 15

    What do tears protect in the eyes?

    surface

  • 16

    Water also lubricates the thin spaces around

    internal organs

  • 17

    In the chest, water serves as a lubricant as the rib cage slides over several internal organs during:

    breathing

  • 18

    Water moistens food during this process and ends with the passage of water-softened feces through the anus.

    ketones

  • 37

    Tertiary alcohols cannot be further oxidized due to its:

    lack of alpha hydrogen

  • 38

    The enzymes have a higher affinity for this alcohol, which is why it is given to a victim of methanol poisioning as treatment.
