Unripe fruits are hard and tart. Ripening is a process that sweetens and softens the fruit to make it more attractive to animals who will eat the fruit and disperse the seeds. A plant hormone, ethylene, leads to the ripening of many fruits. Once ethylene starts being pro- duced, it initiates a feedback loop that causes more ethylene to be produced, increasing the rate of ripening. Which of the following best identifies and describes the feedback loop initiated by the pro- duction of ethylene? A It is a positive feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. B It is a negative feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus. с It is a negative feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. D It is a positive feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus.

Question
Unripe fruits are hard and tart. Ripening is a process that sweetens and softens the fruit to make it more attractive to animals who will eat the fruit and disperse the seeds. A plant hormone, ethylene, leads to the ripening of many fruits. Once ethylene starts being pro- duced, it initiates a feedback loop that causes more ethylene to be produced, increasing the rate of ripening. Which of the following best identifies and describes the feedback loop initiated by the pro- duction of ethylene? A It is a positive feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. B с D It is a negative feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus. It is a negative feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. It is a positive feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus.
