Impulses are conducted by myelinafed axons by jumping from node to node in a process called a(n):
a. action potential.
b. excitatory postsynaptic potential.
c. saltatory conduction
d. monosynaptic reflex
e. depolarization.

c. saltatory conduction  

Explanation:

An electrical impulse begins at the upper end of the neuron. This area is known as the axon ridge, and this ensures that the electrical impulse will travel in one direction only.

Through the myelin, the electrical impulse jumps from one node to another, instead of having to travel the entire distance from the axon. This type of signal conduction is called saltatory conduction.

Saltatory conduction speeds up impulse movement, as some axons may be up to one meter long. With this, the body achieves fast and efficient nerve conduction, and it is what allows you to react so quickly during reflexes.

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.  

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
