(A) Short-term adaptation refers to physiological or behavioral changes that occur within an individual's lifetime to cope with environmental stress.$(1)$ Accumulation of melanin in the skin is a physiological response to $UV$ exposure,which is a short-term adaptation.$(2)$ Utilization of stored fat during hibernation is a metabolic adaptation to survive periods of food scarcity,which is a short-term adaptation.$(3)$ Seed dormancy is a long-term evolutionary strategy to ensure germination under favorable conditions,not a short-term adaptation.$(4)$ Phototropism and geotropism are growth responses (tropisms) inherent to plant development,not short-term adaptations to environmental stress.Therefore,only $(1)$ and $(2)$ are examples of short-term adaptation.
