C D Which of the following local environmental changes will not have global effects?

b. an increase in the annual melt season in the Antarctic peninsula
C. the early arrival of spring in New Hampshire

a

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
