- Which of the following is the correct definition of positive feedback? a The process by which the body neglects homeostasis. b A mechanism in which the body's response to a stimulis opposes the stimulus. c A mechanism whereby the body responds to a stimulus by acting to enhance the stimulus d The dynamic equilibrium maintained by an integrating center which causes an effector to respond to the stimulus received by the receptor.Which of the following is true of positive feedback? a. The change is opposite that of negative feedback b. The effector turns off the response c. The change is amplified What is the difference between the answers a & b?The state of maintaining a constant internal environment iscalleda. reproduction.b. homeostasis.c. responsiveness.d. growth.
- Which of these statements about homeostasis is true? a.The internal environment is maintained absolutely constant. b.Negative feedback mechanisms act to correct deviations from a normal range within the internal environment. c.Homeostasis is maintained by turning effectors on and off. d.All of these are true.Write a long response that thoroughly explores examples of structure and function working together at the following levels in the interest of maintaining homeostasis: A – Organ B – Organ System C – Organism Be specific at each level of organization while keeping the greater good of the whole body in mind. If there was significant dysfunction at the organ level, predict how the effects of that flaw might ripple though higher levels of organization mentioned above? How might this affect the overall health of the person?Explain how homeostasis is maintained (use the term feedback loop, stimulus, response, effector, sensor, control center and set point )
- In a positive feedback loop: O Processes lead back to homeostasis O Processes lead away from homeostasis The effect of the original stimulus is increased 2nd and 3rd answer are correct_______ is a state in which an organisms internal environment is maintained within a tolerable range.In a negative feedback loop: O Processes lead back to homeostasis O Process lead away from homeostasis The effect of the original stimulus is increased 2nd and 3rd Choice are correct
- Which of the following statements best describes homeostasis? a. Keeping the body in a fixed and unaltered state b. Dynamic equilibrium c. Maintaining a near-constant internal environment d. Altering the external environment to accommodate the body's needsMatch the body temperature control item to the appropriate location in the negative feedback loop. Effector when variable is low Effector when variable is high Control center Sensor Controlled variable A. Muscles for shivering and goosebumps B. Nerves in skin C. Brain D. Sweat glands E. TemperatureWhich of the following statements is CORRECT in describing the positive feedback control systems in our body? Group of answer choices The response counteracts the stimulus, shutting off the response loop. The response reinforces the stimulus, sending the variable farther from the set-point. The response is able to move the variable closer to the set-point. The response is able to move the variable farther from the set-point by suppressing the stimulus.
