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.

Reproductive fitness
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
Mutation
Artificial selection(breeding)
Lamarck
Modes of Selection
17. Form of reproduction more used because it creates Variation
Cuvier
Micro - sort
Sexual reproduction
Hardy- Weinberg equilibrium
18. Set sail on the HMS Beagle to travel the islands and areas for signs of evolution; First book written in 1839 'voyage of the Beagle'; Second book published in 1859 'The Origin of Species by means of Natural Selection
Charles Darwin
Molecular similarity
Restriction enzymes
Germinal choice
19. 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
Mate choice/non - random mating
Sexual dimrphism
Pluripotent stem cells
Natural selection does not make perfect individuals
20. The process of sperm sorting; separating the male sperm from the female sperm; difference told by swimming speed; boy sperm swim faster than girl sperm; Theory might have flaws in it though - only works 50% of the time
Restriction enzymes
Reproductive fitness
Ericson Method
DNA fingerprinting
21. Closely related organisms have more similar DNA sequences and protein structures

Heterozygote Advantage
Mutation
Molecular similarity
22. An accumulation of genetic charges over a certain amount of time
Lyell
Directional selection
Asexual reproduction
Descent with Modification
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
Descent with Modification2
Sexual dimrphism
Descent with Modification
24. Direct competition for mates with the same sex
