TEST BANK FOR ANATOMY & PHYSIOLOGY: AN INTEGRATIVE APPROACH 4TH EDITION MICHAEL MCKINLEY VALERIE O’LOUGHLIN THERESA BIDLE ISBN10: 1260265218

1) If a scientist forms and tests a hypothesis, but gets unexpected results, what is a logical next step? Check all that apply. A) Accept the original hypothesis B) Reject the original hypothesis C) Revise the original hypothesis D) Design a new experiment based on a new or modified hypothesis. 2) Some researchers think pheromones are important tools in human communication. Pheromones are chemical signals that one individual sends to another. What research questions might be asked by anatomists, and what questions might be asked by physiologists, to determine if pheromones are important to humans? 3) Iron atoms help our blood transport oxygen. Describe each level of anatomical structural complexity for an iron atom in your blood, working from the simplest level (atom) to the most complex (organism). 4) If someone speaks too loudly into a microphone, a public address system will sometimes produce a loud whistle of amplified feedback. Explain whether this is an example of negative or positive feedback, and explain how the microphone, control box,and speaker of the system serve as the different components of a feedback loop.
