Question 1
What term describes the process by which biological systems maintain a stable internal environment despite external changes?
Explanation
Homeostasis refers directly to the physiological processes that organisms use to regulate their internal environment.
Question 2
Which of the following is an example of negative feedback in homeostasis?
Explanation
Negative feedback works to counteract changes, such as sweating to cool the body when temperature increases.
Question 3
Which hormone, produced by the pancreas, lowers blood glucose levels?
Explanation
Insulin is responsible for decreasing blood glucose levels by facilitating the uptake of glucose into cells.
Question 4
Homeostatic mechanisms that amplify a physiological response until a specific process is completed are known as what?
Explanation
This is characteristic of Positive Feedback, which enhances a response until a finish point is reached, such as childbirth.
Question 5
The hypothalamus plays a crucial role in the regulation of which homeostatic parameter?
Explanation
The hypothalamus is essential for maintaining body temperature through various physiological responses.
Question 6
What condition may arise from an inability to properly regulate insulin levels in the body?
Explanation
Diabetes Mellitus is characterized by impaired insulin regulation, leading to abnormal blood sugar levels.
Question 7
Which organ is primarily responsible for regulating fluid and electrolyte balance in the body?
Explanation
The kidneys help maintain fluid and electrolyte balance through filtration and reabsorption processes.
Question 8
What common misconception about homeostasis is addressed in the material?
Explanation
A common misconception is that homeostasis is static; in reality, it is a dynamic and continuous process.
