  1. Control Sample
  2. Archaea
  3. Genome
  4. Experimental Variable
  5. Genome Characteristics
  1. a a sample that receives no treatment during an experiment, and demonstrates what happens if no experimental variables are applied.
  2. b One of two prokaryotic domains of life, the other being Bacteria. Unicellular Prokaryote.
  3. c 1. Stores information in a stable form: The genome of every organism stores information that provides a blueprint to create its characteristics.

    2. Provides continuity from generation to generation: The genome is copied and transmitted from generation to generation.

    3. Acts as an instrument of evolutionary change: Every now and then, the genome undergoes a mutation that may alter the characteristics of an organism. In addition, a genome may acquire new genes by horizontal gene transfer. The accumulation of such changes from generation to generation produces the evolutionary changes that alter species and produce new species.
  4. d entire set of genetic information that an organism carries in its DNA
  5. e independent variable, the component or factor being tested
