Answers
What are the three main domains of life? - CORRECT ANSWER - Eukarya, Bacteria, and
Archaea
Which Kingdoms are Eukaryotes? - CORRECT ANSWER - Animalia, Fungi, Protista,
and Plantae
All of these domains share an ancestor that came around about________ - CORRECT
ANSWER - 3.5 bya
Archaea - CORRECT ANSWER - This kingdom of prokaryotes (simple cells that do not
have nuclei)
Bacteria - CORRECT ANSWER - Second group of prokaryotes, convert light to energy.
Protista - CORRECT ANSWER - unicellular eukaryotes
Fugi - CORRECT ANSWER - non photosynthetic organisms that digest their food
externally.
What are the fundamental properties that all living things have? - CORRECT ANSWER -
Cellular organization, energy utilization, homeostasis, growth, development, and reproduction
and heredity.
Hierarchial organization - CORRECT ANSWER - 1. Atoms
2. Molecules
, 3. Macromolecules (large complex molecules, DNA).
4. Organelles
5. Cells
6. Tissues (groups of similar cells)

8. Organ System (Nervous System)
9. Organisms
10. Population (groups of organisms)
11. Species

14. Biosphere
Emergent Properties - CORRECT ANSWER - result from a way in which components
interact, and often cannot be guessed by looking at the parts themselves
Reductionism - CORRECT ANSWER - Understanding a complex system by reducing it to
its working part.
inherent limitation: emergent properties (cannot be predicted based on the working parts)
Holist - CORRECT ANSWER - contend that a complete understanding of a complex
system cannot be elucidated merely by studying its piece and parts.
Cell Theory - CORRECT ANSWER - All living things are made of one or more cells
All cells come from preexisting cells
all cells are the basic units of living
Radiometric dating - CORRECT ANSWER - cosmic radiation N14 to C14 in the
atmosphere. C14 is taken by humans. Organisms stop taking C14 when they die. C14 slowly
