  1. CHEMISTRY OF LIFE REVIEW

  2. True or False • Matter (atoms) obey the same rules of chemistry whether they are in living or non living things.

  3. FILL IN THE BLANK • If we take a living thing apart, we eventual end up with ____________

  4. MULTIPLE CHOICE • Life builds from atoms to form many levels of organization. What happens at each new level? • A vital force becomes apparent • Rules of chemistry change • New properties emerge • Nothing changes

  5. LIST • LIST 12 LEVELS OF BIOLOGICAL ORGANIZATION

  6. FILL IN THE BLANK All living and non-living things are composed ________________. HINT-takes up space and has mass

  7. SHORT ANSWER • Where do living things get there matter from?

  8. SHORT ANSWER • Why must matter be recycled?

  9. FILL IN THE BLANK • Matter is composed of ______________ • HINT-A pure substance that can’t be broken down any further by ordinary chemical means

  10. LIST • What are the six elements that make up 98% of living things?

  11. SHORT ANSWER • How can you CHNOPS to evolution?

  12. FILL IN THE BLANK • 3-4 different types of CHNOPS elements combine to make the ______________ of living things. HINT-Two or more different elements chemically combined in a fixed ratio.

  13. SHORT ANSWER • What are trace elements?

  14. FILL IN THE BLANK • Each type of element consists of one type of _____________. HINT-Smallest unit of matter that still retains the properties of an element

  15. MULTIPLE CHOICE • What determines the properties of an element? A. Structure of atom B. Arrangement of atoms within a compound C. Structure of a molecule D. The nucleus of an atom
