Flies would likely have benefitted less from acclimation if the temperature had changed several times per generation instead of once every generation.
a. true
b. false
Ans: a. true
(If temperatures fluctuated several times per generation, flies that developed a certain way would only enjoy the benefits during some portions of their life and would suffer the costs during other portions; for example, a fly that acclimated to 25°C during development would suffer each time the temperature switched to 16°C during its life.)
