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).

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
