Generally speaking, in homeostasis, when there is an adverse or disrupting external stimulus
all variables are maintained within a narrow range simultaneously
all variables will be maintained in stable condition
the variable related to the stimulus will be altered to counteract the stimulus, often at the expense of other variables
the variable related to the stimulus will be altered without involving any other variables

Homeostasis d. metastasisarrow_forwardWhich 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.arrow_forwardWhich 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.arrow_forward
- Body too warm Body too cold Body Body cooler warmer Homeostasis is the control process that " keeps things the same". The mechanism that maintains homeostasis dampens change in the system. When a given characteristic rises above the normal level, a response results to lower the characteristic down to the normal. Similarly, when a given characteristic drops below the normal level, a response results to raise the characteristic up to the normal. This mechanism that dampens change and maintains a stable state is called O natural selection O hydrogen polarity O negative feedback O local response O uniformatarianism Shivering Body cools Sweating Body warmsarrow_forwardHomeostasis is best described as maintaining a(n): O stable and optimal internal environment O deviation in the internal environment O fixed, constant internal environment O internal environment that matches the external environment state of equilibrium between the external and internal environmentarrow_forwardA negative feedback system is one in which a variable is changed in the same direction as the original change that initiated the system the initiating variable is always reduced (made more negative) a variable is changed in the opposite direction to the original change that initiated the system two opposing variables are played against one other the initiating variable is always increased (made more positive)arrow_forward
- . A defective control center (a homeostatic control mechanism component) can lead to: undetermined variable set point inappropriate response to stimuli incorrect analysis of input from effector a and b a, b, and carrow_forwardA response is the body's reaction to the stimulus. What's the response in these situations? Stimulus: You hear a loud noise · A large dog runs toward you, growling and barking You eat a large candy bar You have not eaten in six hours You have strep throatarrow_forwardReflexes: If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don't have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment). Reflexes are responses that protect the body from potentially harmful events that require immediate action. They involve relatively few neurons (nerve cells) so that they can occur rapidly. There are a wide variety of reflexes that we experience every day such as sneezing, coughing, and blinking. We also automatically duck when an object is thrown at us, and our pupils automatically change size in response to light. These reflexes have evolved because they protect the body from potentialy harmful events. Most reflexes protect people from injury or deal with things that require immediate action. Reflex actions do not involve the higher brain regions involved in conscious…arrow_forward
