Which of the following is an example of a possible physiological effect a river dam could impose on migrating Pacific salmon?
It could completely block the salmon's migration.
correct
incorrect
The salmon may get past the dam, but their efforts cost them too much energy.
correct
incorrect
The salmon may get past the dam, but subsequent navigation may be impaired.

correct
incorrect
Gills evolved as an organ to extract oxygen from the water.

Which statement regarding conformity and regulation is
false
?
Animals can be both regulators and conformers.
correct
incorrect
Conformity and regulation are extremes; intermediate responses are more common.
correct
incorrect
Animals frequently show conformity with respect to some characteristics while regulating others.
