To properly classify organisms within the newly discovered Solaria fungal ecosystem, botanists adhere to strict taxonomic rules. A specimen is categorized as a bioluminescent species only if it synthesizes the compound luciferyl. Moreover, no fungus in this ecosystem synthesizes luciferyl without also maintaining a symbiotic relationship with local root systems. Finally, exhibiting a rapid spore-dispersal mechanism requires that the fungus not maintain a symbiotic relationship with local root systems.
Based on the botanists' taxonomic rules, which one of the following statements must be true?
- Any specimen in the Solaria ecosystem that exhibits a rapid spore-dispersal mechanism is not categorized as a bioluminescent species.Cevap
- BIf a specimen in the ecosystem does not exhibit a rapid spore-dispersal mechanism, then it synthesizes the compound luciferyl.
- CAny specimen that synthesizes the compound luciferyl must be categorized as a bioluminescent species.
- DAny fungus that maintains a symbiotic relationship with local root systems must synthesize the compound luciferyl.
- EMost specimens that do not exhibit a rapid spore-dispersal mechanism are categorized as bioluminescent species.
Cevap
The statement declaring that any specimen exhibiting a rapid spore-dispersal mechanism is not categorized as a bioluminescent species.
The stimulus provides three conditional statements. First: Bioluminescent -> Synthesizes luciferyl. Second: Synthesizes luciferyl -> Symbiotic relationship. Connecting these gives: Bioluminescent -> Synthesizes luciferyl -> Symbiotic relationship. The third statement is: Rapid spore-dispersal -> NO Symbiotic relationship. The contrapositive of this third statement is: Symbiotic relationship -> NO Rapid spore-dispersal. By attaching this contrapositive to the end of our initial chain, we establish a complete unbroken chain: Bioluminescent -> Synthesizes luciferyl -> Symbiotic relationship -> NO Rapid spore-dispersal. This proves that any bioluminescent species cannot have a rapid spore-dispersal mechanism. The contrapositive of this overarching deduction is that any fungus with rapid spore-dispersal is not bioluminescent. The correct answer choice explicitly states this valid contrapositive.
