Phasic receptors adapt quickly to a stimulus. For that reason, they are good at detecting changes instead of constantly signalin
Ainat [17]

Answer:

TRUE

Explanation:

Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are  fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when  stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.

If all the droplets were the same size, which would fall most slowly through the apparatus?
Alenkinab [10]
If all the droplets were the same size, the droplet with the smallest charge <span>would fall most slowly through the apparatus. Basically, buoyancy is the same for all droplets but the electrical force would be different for each. The higher the electrical force the greater is the gravitational pull towards that droplet. Therefore, the droplet that has the </span>smallest charge<span> would drop most slowly.</span>
