Which of the following is a good definition of homeostasis?(2 points) Responses Homeostasis means that our body monitors the value of several parameters and prevents them from ever changing. Homeostasis means that our body monitors the value of several parameters and prevents them from ever changing. Homeostasis means that our body doesn't regulate the value of different body parameters. Homeostasis means that our body doesn't regulate the value of different body parameters. Homeostasis means that our body monitors the value of several parameters and restores them to their correct value after any alteration. Homeostasis means that our body monitors the value of several parameters and restores them to their correct value after any alteration. Homeostasis means that we stand still all the time.

Answer 1

The best definition of homeostasis from the provided options is:

Homeostasis means that our body monitors the value of several parameters and restores them to their correct value after any alteration.

This definition accurately reflects the concept of homeostasis, which involves the regulation and maintenance of stable internal conditions despite changes in the external environment.

Answer 2

Which of the following variables do our bodies regulate:(2 points) Responses Blood volume Blood volume Glucose concentration in blood Glucose concentration in blood Body temperature Body temperature All answers are correct

Answer 3

The correct response is: All answers are correct.

Our bodies regulate various variables, including blood volume, glucose concentration in blood, and body temperature, to maintain homeostasis.

Answer 4

Which of the following is an example of positive feedback to indirectly maintain homeostasis?(2 points) Responses the chemical reactions involved in blood clotting the chemical reactions involved in blood clotting your blood vessels dilate and you begin to sweat in response to elevated body temperature your blood vessels dilate and you begin to sweat in response to elevated body temperature your blood vessels constrict and you begin to shiver in response to low body temperature your blood vessels constrict and you begin to shiver in response to low body temperature your coach compliments you on your performance in practice

Answer 5

The correct response is: the chemical reactions involved in blood clotting.

This is an example of positive feedback, where the initial stimulus (injury) leads to a series of reactions that amplify the response (increased clotting) until the problem (bleeding) is resolved. The other options describe mechanisms of negative feedback or unrelated responses.
