Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
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.
1. Believed that change was gradual;Gradualism(the mechanisms of the world - then - are the same today)

2. Results in a tissue or an organ that is identical to the DNA donor

10. 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

12. Cells that can turn into other cells

13. Scientific explanation of how life changes over time - science is based off of evidence - science is obtained with observation and testing - science is always open to question
Lamarck
Microevolution
Recombinant DNA technology
Evolution
14. Came up with the term Uniformitarianism(mechanisms for change in the past still occur today; believed at first there was no evolution

Most organisms are...
Natural selection does not make perfect individuals
20. Can make large quantities of product; infection free; less expensive than a natural source
Mate choice/non - random mating
Bottleneck effect
Natural selection does not make perfect individuals
Advantages of Recom. DNA tech
21. 1.edits existing variation by using the material it has(variation that exists in population/ no new traits created by natural selection) 2. Has historical constraints(change in old structures) 3. Adaptations are compromises (good for one thing - bad
