Explanation:
In the reflex arc, a signal is generated by the sensory cells and is conducted with the help of interneurons and returns back using motor neurons to bring out the reflex. The nerve pathway taken by a reflex action is known as a reflex arc. In the process, a receptor situated in the skin determines a stimulus. After that the sensory neuron transmits electrical impulses towards a relay neuron, and this relay neuron associates sensory neurons to the motor neurons. The motor neurons further transmits electrical impulses to an effector. The effector eventually generates a response.
It is crucial to avoid air bubbles in the assembled potometer. The plant stem must be cut under water to prevent airlocks forming in the xylem. All fittings must be tight so that the only way the apparatus can lose water is by the plant transpiring.
Because mutations do not always result in an amino acid change.
