Which of the following statements best explains the change in herbicide-resistant horseweed populations over time? A
Individual horseweed plants that are resistant to the herbicide increased over time by surviving and reproducing, and passing their herbicide-resistant genes to their offspring.
B
Horseweed plant populations resistant to the herbicide increased over time by growing in areas where the herbicide is not present, increasing their chance of survival.
с
Numbers of individual horseweed plants remained the same over time, however they reproduced at different rates. Since the herbicide-resistant individuals can reproduce faster
and increase their genes in the population, the population became more resistant over time.
D
Numbers of individual horseweed plants remained the same over time, however they developed genes that make them more resistant to herbicides. As the resistant individuals
pass their genes on to other populations, the horseweed plants become more resistant over time
