Two plant species interbreed and produce hybrid offspring. These offspring are unable to reproduce with either of the parent spe
cies, but they are fertile when breeding with each other. Which of the following can you infer from this information? Allopatric speciation has occurred as a result of interrupted gene flow.
Hybrid zones fused and have caused reproductive isolation.
Sexual selection has formed a new species due to prezygotic barriers.
Sympatric speciation has resulted in the formation of an allopolyploid species.
Silicon dioxide is dissolvable in water and has a high melting point because the atoms in the dioxide has a strong bond between them, which requires a lot of energy to break them.
Land development creates impervious surfaces through construction of roads, parking lots, and other structures. Impervious surfaces:
Contribute to nonpoint source water pollution by limiting the capacity of soils to filter runoff.
Affect peak flow and water volume, which heighten erosion potential and affect habitat and water quality.
Increase storm water runoff, which can deliver more pollutants to water bodies that residents may rely on for drinking and recreation.1 Storm runoff from urban and suburban areas contains dirt, oils from road surfaces, nutrients from fertilizers, and various toxic compounds.
