  1. 2. In this type of reproduction, the cells from two different parents unite to produce the first cell of the new organism
  2. 5. An experiment in which only one variable is changed
  3. 6. A logical interpretation based on what scientists already know
  4. 10. The act of noticing and describing events or processes
  5. 11. The variable that is observed and that changes in response to the independent variable
  6. 13. In this type of reproduction, the new organism has a single parent
  7. 14. A group that is exposed to the same conditions as the experimental group except for changes in the independent variable
  8. 15. The process by which organisms keep internal conditions constant
  9. 16. The science that employs scientific methodology to study living things

  1. 1. A tentative scientific explanation that can be tested by further observation or experimentation
  2. 2. A signal to which an organism responds
  3. 3. A tested, highly reliable scientific explanation that unifies many repeated observations
  4. 4. The variable that is deliberately changed
  5. 7. The process by which any organism can change to survive
  6. 8. Comes in two types: quantitative- numbers obtained by counting or measuring, and qualitative- descriptions that cannot be measured
  7. 9. A personal, rather than a scientific, point of view for or against something
  8. 11. This molecule carries the directions for inheritance
  9. 12. The combination of chemical reactions that carry out life processes
