The substance must be able to alter its physical characteristic (for example, its color) in accordance to a change in pH. One example of this is litmus paper, which becomes red under acidic conditions and blue under basic conditions.
Answer:
Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.

hope this helps :D
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.
