Is natural radioactivity is random and artificial radioactivity is controlled?
The same laws and rules are valid for radioactive natural and artificial isotopes.
Why is natural selection random?
No. Natural selection is the non-random survival of randomly varying replicators. The random variation part could be thought of as mutation and recombination that the non-randompart, natural selection, works with.
Why is light from a common lamp nonpolarixed?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
Why is light from a common lamp or from a candle flame nonpolarized?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.

What are the Elements of the theory natural selection?
Replication random variation Non-random survival
What are controlled and uncontrolled changes?
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
What describes genetic drift?
random changes in allele frequency (apex) [Correct]
What is a study of small group behavior of a selected random sample called?
controlled experiment
A study of small group behavior of a selected random group is call a?
controlled experiment
What is genetic drift increased by?
Lack of a selection factor. In the absence of selection pressure from natural, sexual or artificial sources, the propagation of random genes would increase. Mutation rates may also be tuned to optimise genetic drift (emphasis on may!).
What is natural selectiuon?
Natural selection is the non-random survival of randomly varying replicating organisms.
