Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
I've checked all the options and I think that the right answer looks like this: Mollusks have highly developed olfactory receptors.
i dont know where the choices are but plant gain energy from sunlight and they use it to make food through photosynthesis.
Hope it helps bro :D
Answer:
Your answer would be betwen 400 to 700 nm
Answer:
