Purple coneflower is a common plant in Indiana. One year during a drought, the plants that had a shorter growing period survived
better than the ones with a longer growing period. What effect did this MOST LIKELY have on the plants? A) There was no change. B) The plants all died out. C) The plant adapted to have a longer growing period. D) The plant adapted to have a shorter growing period.
D. The plant adapted to have a shorter growing period
Over a period of time, if a certain selection pressure is applied on a population of organisms, the ones that are more suited to survive are successful. In this case, if the period of drought continues, then the plants will become more and more adapted to have shorter growing periods.
