14
The theory of evolution through natural selection is considered a
scientific
theory because
it is supported by a massive body of evidence
The mitochondria is the powerhouse of the cell.
it is broad enough in scope to explain many observations
it is general enough to provide many testable hypotheses

16
The evolutionary effects of genetic drift are greatest when _____.
competition is weak
The population size is large
The population size is small
Sexual selection occurs
17
What H-W condition would be most difficult to meet studying a flatworm population in a lab?

No selecton
No gene flow
No mutation
18
Charles Darwin completed his famous voyage upon the seafaring vessel named....

19
A population of organisms will not evolve if
All individual variation is due to environmental factors
The environment is changing but at a relatively slow rate
The population size is large
There is competition among individuals
20
Only twins have the same DNA. The main source of genetic variation among human individuals is
environmental effects
the reshuffling of alleles in sexual reproduction.
geographic variation within the population.
