For an ecological study, you monitor herbivore-plant interactions in a rainforest and notice that mammalian herbivores avoid the leaves of a particular species of plant. However, a number of tiny herbivorous insect generalists that feed by piercing individual plant cells with their mouthparts appear capable of completing their entire life cycle feeding on this same species. You hypothesize that in this species the chemical defenses are:

Imagine a person stepping on a pin and pulling his or her foot away. look at the reflex arc of this scenario below. which statement best describes the image? a)the sensory nerve carries the signal from the effector to the interneuron, and the motor neuron carries the signal to the receptor. b)the motor nerve carries the signal from the receptor to the interneuron, and the sensory neuron carries the signal to the effector. c)the sensory nerve carries the signal from the receptor to the interneuron, and the motor neuron carries the signal to the effector. d)the sensory nerve carries the signal from the receptor to the motor neuron, and the interneuron carries the signal to the effector.
