Questions and Answers

1.

The balance of all of a living organisms internal conditions is known as what?
- A.
  
  Equilibrium
- B.
  
  Osmosis
- C.
  
  Balance
- D.
  
  Homeostasis
Correct Answer
D. Homeostasis

Explanation
Homeostasis refers to the balance of all internal conditions in a living organism. It is the body's ability to maintain a stable and constant internal environment despite external changes. This process involves various physiological mechanisms that regulate temperature, pH levels, blood pressure, and other vital functions. Homeostasis ensures that cells can function optimally and is crucial for the overall health and survival of an organism.

2.

Which of the following would be something regulated by homeostasis?
- A.
  
  Body Temperature
- B.
  
  Color
- C.
  
  Taste
- D.
  
  Intelligence
Correct Answer
A. Body Temperature

Explanation
Homeostasis is the body's ability to maintain a stable internal environment. Body temperature is regulated by homeostasis to ensure that it remains within a narrow range that is optimal for the body's functioning. This is achieved through mechanisms such as sweating or shivering to cool or warm the body, respectively. Color, taste, and intelligence are not regulated by homeostasis as they are not related to the body's internal environment.

3.

Which of the following would also be something regulated by homeostasis?
- A.
  
  Acid & Base Levels
- B.
  
  Taste
- C.
  
  Sight
- D.
  
  Reproduction
Correct Answer
A. Acid & Base Levels

Explanation
Homeostasis is the body's ability to maintain a stable internal environment. Acid and base levels in the body are regulated by homeostasis to ensure a balanced pH. The body has various mechanisms, such as the release of bicarbonate ions and the regulation of breathing, to maintain the acid-base balance. This is important for the proper functioning of cells and enzymes. Therefore, acid and base levels are regulated by homeostasis to ensure optimal physiological conditions.

4.

Which system of the body is responsible for helping to maintain homeostasis?
- A.
  
  Digestive
- B.
  
  Reproductive
- C.
  
  Skeletal
- D.
  
  Nervous
Correct Answer
D. Nervous

Explanation
The nervous system is responsible for helping to maintain homeostasis in the body. It controls and coordinates the functions of all other systems, allowing them to work together in balance. It regulates body temperature, blood pressure, heart rate, and other vital functions to keep the body in a stable state. The nervous system also detects and responds to changes in the external and internal environment, ensuring that the body can adapt and maintain a constant internal environment.

Rate this question:
5.

What organ would help to regulate blood glucose levels in the body?
- A.
  
  Lungs
- B.
  
  Pancreas
- C.
  
  Heart
- D.
  
  Brain
Correct Answer
B. Pancreas

Explanation
The pancreas is responsible for regulating blood glucose levels in the body. It produces insulin, a hormone that helps to lower blood sugar levels by allowing cells to absorb glucose from the bloodstream. Additionally, the pancreas produces glucagon, which helps to raise blood sugar levels when they are too low. This balance of insulin and glucagon secretion helps to maintain stable blood glucose levels, ensuring that cells have the energy they need to function properly.
