Which of the following is true of neural impulses in a single neuron? the strength of a neural impulse increases as the strength of the incoming message gets stronger. the strength of a neural impulse is the same each time the neuron fires. the neuron may fire during the absolute refractory period. the strength of a neural impulse decreases as the strength of the incoming message gets stronger. the lack of a neural impulse is different each time the neuron fires.

Option (2).

Explanation:

Neural impulse may be defined as the the way by which nerve cell can communicate with each other in the body. These nerve impulse travels in the form of electrical signals in the neurons.

The strength of the nerve impulse changes in the different neuron. The neural impulse in a single neuron has the same strength each time when the neuron fires.

Thus, the correct answer is option (2).
