<span>Sensitive to stimuli that stretch, compress, twist, or distort their plasmalemmae. 3 classes: 1) tactile- provide sensations of touch, pressure, and vibration 2) baroreceptors- detect pressure changes in the walls of blood vessels, digestive, reproductive, and urinary tracts. 3) proprioceptors- monitor the position of joints and muscles are are the most complex general sensory receptors.</span>
it’s either the 1st or 2nd one, if i had to guess i’d say the second one. hope that helps :)
Building models doesn't actually help scientists observe phenomena. Scientists build models to describe how nature and systems operate then make observations to see if their models match what they observe. Models which don't match what they observe are either alterated or scrapped. Good models are kept and used by the scientific community.
