Synapses are . Question 14 options: a) where neurons make direct contact with one another b) chemical structures that allow dendrites to send their messages to axons c) intersections where the axons of one neuron meet the dendrites of another neuron d) the area where neurons determine whether a stimulus exceeds the absolute threshold or not

C) intersections where the axons of one neuron meet the dendrites of another neuron

Explanation:

In a neuron, a synapse is a site at which the two neurons meet physically with a small gap between them. The synapse is present between the two neurons but when the more than one neuron is involved then it forms a junction where a synaptic. The synapse is formed when the axon of the presynaptic neuron meets the dendrite of the postsynaptic neuron.

The two synapses interact with each other by chemical signals that are the electrical signal of the neuron is converted into the chemical signal which gets passed on via these synapse to another neuron and it is again converted back into the electrical signal.

Thus, Option-C is the correct answer.

the answer to you question is   jet streams

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
