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. 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

2. The idea that characteristics can enhance an organisms survival

Mutation
Lamarck
Neutral Variation
Natural selection does not make perfect individuals
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
Ericson Method
Evolution
Hardy- Weinberg equilibrium
Stabilizing
14. Takes the gene from a needed product - puts it into another organism (usually bacteria) and it will make duplicates of the product
Most organisms are...

15. Mate choice; one sex chooses their mate
Asexual reproduction
Intersexual selection

20. A widely accepted idea with lots of evidence
