Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

12. Takes the gene from a needed product - puts it into another organism (usually bacteria) and it will make duplicates of the product

13. Subset of natural selection that increases the likelihood of mating specifically
Gel Electrophoresis

14. A subset of a population colonizes a new area
Founder effect
Natural selection does not make perfect individuals
Transitional forms
Diploiding
15. A widely accepted idea with lots of evidence
Descent with Modification2
Asexual reproduction
Theory
Neutral Variation
16. First to publish mechanisms for evolution; Had 2 idea: Use and disuse - use it more gets bigger; less it disappears - Inheritance of acquired characteristics - pass on changes to offspring
Stem cells
Neutral Variation
Linnaeus

17. Forms that show how an organisms anatomy change over time

Evolution
Bottleneck effect
22. Results in a genetically identical inidvidual

Reproductive cloning
23. Theory of a stable - nonevolving population in which frequency of alleles do not change; only occurs in large - isolated populations with random mating - and no natural selection or mutations
Hardy- Weinberg equilibrium
Modes of Selection
Stem cells
Hutton
24. Sometimes different species share common ancestors
