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.

Adaptation
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
