The Science of Biology
Across
- 2. In this type of reproduction, the cells from two different parents unite to produce the first cell of the new organism
- 5. An experiment in which only one variable is changed
- 6. A logical interpretation based on what scientists already know
- 10. The act of noticing and describing events or processes
- 11. The variable that is observed and that changes in response to the independent variable
- 13. In this type of reproduction, the new organism has a single parent
- 14. A group that is exposed to the same conditions as the experimental group except for changes in the independent variable
- 15. The process by which organisms keep internal conditions constant
- 16. The science that employs scientific methodology to study living things
Down
- 1. A tentative scientific explanation that can be tested by further observation or experimentation
- 2. A signal to which an organism responds
- 3. A tested, highly reliable scientific explanation that unifies many repeated observations
- 4. The variable that is deliberately changed
- 7. The process by which any organism can change to survive
- 8. Comes in two types: quantitative- numbers obtained by counting or measuring, and qualitative- descriptions that cannot be measured
- 9. A personal, rather than a scientific, point of view for or against something
- 11. This molecule carries the directions for inheritance
- 12. The combination of chemical reactions that carry out life processes
