Determine whether each statement regarding protists is true or false.

Two closely related species of birds (Purple and Green) live in the same region and mate between June and July. Purple males have an elaborate mating dance that involves keeping their wings out and pointing upwards for the duration. Green males’ mating dance involves rapid flapping motions with their wings that creates a humming sound.  When a Green female sees a Purple male’s dance, she never shows interest. When a Purple female sees a Green male’s dance, she will often mate with the male, however, the offspring often die within two weeks of hatching.  Which of the following pre-zygotic and post-zygotic barriers are demonstrated in this scenario?

Male frogs give calls that attract female frogs to approach and mate. Researchers examined mating calls of closely related but separate species of tree frogs in South America. What outcomes could possibly occur where the ranges of two species overlap?

grep will always perform global matching, and no mechanism exists by which it may be disabled. Example output: $> echo “RA = 16 h 41.7 min = 16 + 41.7/60 = 16.695 hrs” | grep -E –color “(+\.)+{1,}”RA = 16 h 41.7 min = 16 + 41.7/60 = 16.695 hrs
