A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

• behavioral isolation
• temporal isolation 
• gametic isolation
• geographic isolation 

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?

• hybrid sterility 
• temporal isolation
• mechanical isolation

The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation 

What is a species? 

• A group of organisms that can mate with each other and produce fertile offspring. 
• A group of organisms that can mate and produce offspring even if those offspring are infertile.
• A group of organisms that genetically are very different from each other. 
• Indivual organisms that live in the same environment.
