Determine whether each statement regarding multicellularity 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?

Indicate whether the output will be “Yes”, “No”, no output, or will it produce an error message for the following bash command.  xyVect=-90.0910if [ `echo “$xyVect > 23.5” | bc -l` == “1” ]; then        echo “Yes”else        echo “No”fi

Indicate whether the output will be “Yes”, “No”, no output, or will produce an error for the following bash command: score=100if [[ $score < 100 || $score == 100 ]]; then        echo "Yes"else        echo "No"fi  

The following if-statement condition will cause a file named “25” to be created: if [[ $x > 25 ]]; then echo True; else echo False; fi

Given a target string of “1024 bytes used”, what would the following regular expression match? (Note: the forward slashes are simply used as delimiters and do not constitute a part of the regex pattern itself). /[0-9]+[ \t]+[a-z]+/

Match the hybrid mating to its correct term for the offspring.
