The condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as 

• sexual dependency
• reproductive isolation
• geographic isolation
• adaptive radiation

The wing of a bat and a humans' arm have different functions and appear very different.  Yet, the underlying anatomy is basically the same.  therefore, these structures are examples of

• geographic isolation
• analogous structures
• homology
• reproductive isolation

Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection? 

• in order to survive exposure to penicillin, bacteria developed a resistance to the drug 
• a few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance
• penicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studies
• some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillin
