The nervous system is composed of or nerve cells. a. receptors b. neurons c. neurotransmitters d. axons

B) Neurons.

Nervous system comprises of two branches - CNS ( Central Nervous System) and PNS (  Peripheral Nervous System). It receives and transmits signals in different parts of the body. Neurons or nerve cells are the basic functional unit of the nervous system. The function of neurons is to transmit the signals by generating action potential.

A typical neuron consists of - Cell body, axon, and dendrites.

Cell body receives signals through dendrites, axon transmits it in the nerve endings. Finally the signals are transmitted to next neuron via signaling molecules called as neurotransmitters. The junction between adjacent neurons is called as neurotransmitter junction or synapse.

The nervous system is composed of (answer B  ) Neurons.

How?:

The neuron is the basic unit in the nervous system. Neurons make up both parts of the Central and Peripheral Nervous systems. It is a specialized conductor cell that receives and transmits electrochemical nerve impulses. A typical neuron has a cell body and long arms that conduct impulses from one body part to another body part.

hey, what do you need . just post the question and i may be able to you : )

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
