1. Science is the...: Collection of unified insights about nature, the
evidence of which is an array of facts.
2. A theory is the...: Generalization that explains many observation - has
been tested and researchers have yet to find evidence that disproves it -
usually generates many hypotheses.

and electrons.
,6. Water provides basis for...: Life.
7. Surface tension is when water molecules...: Bond to each more strongly
that to air.
8. The properties of water include...: - Being polar.
- Having high heat capacity.
- Acts as a solvent.
9. How is pH important to living organisms?: - Most reactions can only occur
at certain acidities. - Enzymes only work at certain pH levels.
10. Organic compounds contain...: Carbon.
11. Carbon is so important in the molecules that make up living organisms
because...: It's ability to form four covalent bonds allows it to create a
variety of other structures.

attract water molecules to one another.: polar covalent / hydrogen
