25 Questions

1.
contains genetic information (DNA) needed to make proteins

2. when one organism feeds on another organism without killing it (ex. lice)

3.
the normal/'do nothing' group

4. an hormone that regulates blood sugar (it tells body to lower glucose in blood when blood sugar is too high)

5.
internal balance in an organism

6. when there is a natural variation (mutation) in insects and the ones with the mutation become resistant to the pesticide; solution to the problem →make a new pesticide

7. organisms that get food from eating other organisms; another word for consumer (animals)

8. the building blocks of protein

9. the best evidence of evolution (includes similar DNA and amino acid sequences); if two species have a lot of DNA in common, they likely evolved from a common ancestor

10. Levels of organization (organize cell, organelle, organism, organ system, tissue and organ from most complex to least complex)

11. a disease you get if insulin is not working properly

12. organisms that get food from eating (consuming) other organisms (animals)

13. the building blocks of carbohydrates

14. a trait that allows a species to survive (ex. strong wings, good eyesight)

15. oil, gas and coal; nonrenewable resources that cause a lot of pollution (cheap BUT bad for the environment)

16. things that stay the same in an experiment; NEVER the variables

17. reproduction that requires two parents makes different offspring

18. double stranded molecule that contains genetic information

19. all cells except sex cells; mutations in these cells are not passed to offspring

20. living factors (plants, animals, bacteria, food)

21. process used to make identical offspring by taking DNA out of a body cell, placing it in an empty egg cell

22.
how cells communicate with each other (hormones and neurotransmitters)

23. diversity (differences) in living things (VERY important!)

24.
process that makes ATP (O2 + glucose → CO2 + H2O + ATP)

25. when organisms with the better traits survive and reproduce; thus being selected by nature
