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.

20. Way more offspring are produced than by sexual reproduction
Most organisms are...

Advantages of Recom. DNA tech
21. Taking good genes to replace bad genes; almost never works; has unintended side effects; sometimes just doesn't work; protein becomes degraded - etc

Advantages of Recom. DNA tech
Theraputic cloning
Gene Therapy
22. The idea that characteristics can enhance an organisms survival
Descent with Modification2
Mutation
Linnaeus
Adaptation
23. 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
Evolution
Lamarck
Historical Context of evolution
Reproductive fitness
24. 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
