How do sensory receptors work?
A receptor is generally a recognition molecule situated on the surface of a cell. A receptor is a molecule that is sensitive to a particular signal and is also able to transmit information to the nucleus in order to control gene regulation. In order for a receptor to function, it must first be activated. The binding of a ligand to the receptor places the receptor in the activated state. Once the receptor is activated, it is now able to transmit signal to the interior of the cell.
How do cells specialize and communicate in order to promote the functioning of an organism?

How are stimuli converted into signals for the body to respond to?
stimuli are converted into electronic signals. Such electronic signals travel by a huge network of nerves throughout the body. These signals converge to the brain, where sensory neurons interpret them and send back an "order" through the Central Nervous System, to the correspondent point of the body where the stimulus has happened. Such "order" may refer to the release of defence cells, or simply tell your arm to touch the point of the stimulus,in order to calm you down, as a simple example. The signal that flows through the nerve, uses a mineral, magnesium, as a basis to conduct the electronic signal. Sodium is another mineral that participates of the process. Such travel may take only miliseconds to reach the brain and to come back.
Which neuron delivers sensations to the cns?
Afferent neurons receive and transmit impulses to the CNS.
Which cell must have action potentials to produce one or more action potentials in the postsynaptic cell?
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.
Why the same devices using cross over cable?
In order for two devices to communicate the transmit signal wire must be connected to the receive wire. A crossover cable accomplishes this. With a straight through cable you would have a transmit signal connected to a transmit signal, which is similar to two people talking at once (and no one listening). In a network scenario a straight through cable would cause constant collisions.
Why is modulation necessary in radiobroadcasting?
Modulation in radio broadcasting is important because it is necessary to adjust the carrier signal so that the information in the modulating signal can be broadcasted. You must have modulation in order to transmit thru a radio wave.
What is need of module?
we modulate audio signal due to following reasons: -audio is a low frequency signal that cannot travel longer distance due to low energy -if we transmit the signal without modulation then the height of antenna will be of the order of several thousand kilometers that is impractical
Explain if transmit baseband signal directly in a wireless system and why?
An antenna must be the order of magnitude of the, wavelength signal in size to be effective. Using only baseband transmission, FDM could not be applied and (Path loss, penetration of obstacles, reflection, scattering and diffraction. All the effects depend onthe wavelength of a signal.

What is the difference between time division multiplexing and space division multiplexing?
The difference is the way the data is separated and transmitted between two points. In Space Division the data is separated physically i.e. the carrier medium is divided into different channels. This could be by using different wires, waveguides, optical cables, etc, or by frequency i.e. radio channel, carrier frequency. Time Division uses the same channel in one of the above but different data is given a specific order and location in time for transmission. e.g. Synchronsation followed by type (a) data, then type (b) data followed by a checksum. The whole process is repeated continuously until transfer is complete.
Which modulation can reduce the noice of signal?
Signals of different frequencies cannot interfere with each other. For example can audio waves (speech) interfere with AM or FM signals?? So when we perform modulation we just transfer the message to another amplitude/frequency/phase. Hence they will never interfere with signals which are not in the same range as them. Regards Arvind
How is sinusoidal signal produced?
You may use a filter which will round off the square pulse to sine wave.The higher order the filter the better the SINE wave . The Square pulse and the sine wave must both be tuned to our required frequency
Are signal words are used mostly for chronological order or sequence?
Depends on what you mean by signal words this is not common grammar terminology. Possibly the answer is both signal words show chronological order or sequence
