, Biological populations of same species become reproductively isolated
from each other due to non physical barriers.
How does a scientific theory differ from a scientific hypothesis?
A) Theories are proposed to test scientific hypotheses
B) Theories are usually an explanation for a more general phenomenon; hypotheses
typically address more specific issues
C) Confirmed theories become scientific laws; hypotheses become theories
D) Hypotheses are usually an explanation for a more general phenomenon; theories
typically address more specific issues
E) You can do experiments to prove hypothesis but not theory
