Which of the following is not an example of homeostasis?
A) perspiring in order to restore normal body temperature
B) feeling hungry and eating to restore the level of blood glucose to normal
C) feeling hungry at the sight of appetizing food**********
D) quenching thirst and drinking water to hydrate the body
E) all of the above are examples of homeostasis
Is it only one answer?
The correct answer is C) feeling hungry at the sight of appetizing food. While the feeling of hunger itself is a component of homeostasis, feeling hungry at the sight of appetizing food is not directly related to maintaining stable internal conditions in the body. It is a response to external stimuli rather than an internal regulation.
To determine which of the options is not an example of homeostasis, we need to understand what homeostasis means. Homeostasis is the ability of an organism to maintain stable internal conditions despite changes in the external environment. It involves a series of physiological processes that work together to keep the body balanced and functioning properly.
Let's analyze each option to see if it demonstrates the concept of homeostasis:
A) Perspiring in order to restore normal body temperature: This is an example of homeostasis because sweating helps cool down the body when it becomes too hot.
B) Feeling hungry and eating to restore the level of blood glucose to normal: This is also an example of homeostasis. When the blood glucose level drops, feeling hungry triggers the desire to eat and restore the balance.
C) Feeling hungry at the sight of appetizing food: This option is not an example of homeostasis. Feeling hungry at the sight of food is more of a conditioned response than a physiological process to maintain internal balance.
D) Quenching thirst and drinking water to hydrate the body: This is an example of homeostasis because drinking water helps maintain the body's fluid balance when it becomes dehydrated.
E) All of the above are examples of homeostasis: This statement is incorrect because option C (feeling hungry at the sight of appetizing food) is not an example of homeostasis.
Therefore, the correct answer is C) feeling hungry at the sight of appetizing food, as it does not demonstrate the principle of homeostasis.
