Fill in the blank(s) with correct word
One patient at your audiology clinic has an actin defect, and another patient has a microtubule defect. How might these defects affect the function of their hair cells in hearing?
Hair cells are delicate sensors of sound, movement, and gravity. They are stimulated by movement of the stereocilia -- which are actually microvilli -- and the single kinocilium, which is a true cilium. A. Neither actin nor microtubule mutations will disrupt hair cell cilia function. B. Only the actin mutation will affect hair cell cilia function. C. Only the microtubule mutation will affect hair cell cilia function. D. Both can create problems in hair cell cilia function. Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about hair cells? What other information is related to the question? Choose Answer Given what you now know, what information is most likely to produce the correct answer? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
