The tendency of the body to maintain stable internal conditions is called____ .
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
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

O effector O gland O receptor O muscle none of the above Next ► « Previousarrow_forwardHomeostasis can be defined in which of the following ways: using the least amount of energy maintaining a stable internal environment within narrow limits regardless of environmental changes O maintenance of a static state with no deviation from predetermined set points a dynamic state within an unlimited range, depending on circumstances O more than one of the above Next » « Previousarrow_forwardBecause the body's goal is to maintain stable, homeostatic conditions, positive feedback occurs more often than negative feedback.

- 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.arrow_forwardwhat can go wrong if specific homeostatic disrupted? Functions arearrow_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
