Questions and Answers
- 1.
If the environment gets cold, we will often shiver in order to:
- A.
Lower the body temperature
- B.
Get frost bite
- C.
Increase body temperature
Correct Answer
C. Increase body temperatureExplanation
When the environment gets cold, our body temperature tends to drop. Shivering is a reflex action that helps increase body temperature by generating heat through muscle contractions. The rapid contractions of muscles produce heat, which helps to warm up the body. Therefore, shivering is a natural response to cold temperatures in order to maintain a stable body temperature.Rate this question:

The maintenance of an organism’s internal environment is called
- A.
Homeostasis
- B.
Osmosis
- C.
Cell transport
Correct Answer
A. HomeostasisExplanation
Homeostasis refers to the process by which an organism maintains a stable internal environment despite external changes. It involves regulating various factors such as temperature, pH levels, and nutrient levels within a narrow range. This is crucial for the proper functioning of cells and overall survival of the organism. Osmosis, on the other hand, is the movement of water molecules across a semi-permeable membrane, and cell transport refers to the movement of molecules and ions across cell membranes. While both osmosis and cell transport are important processes, they are not synonymous with the maintenance of an organism's internal environment like homeostasis is.Rate this question:

Homeostasis in the human body is often maintained by a:
- A.
Negative feed back loop
- B.
Positive feed back loop
- C.
Brain loop
Correct Answer
A. Negative feed back loopExplanation
Homeostasis is the process by which the body maintains a stable internal environment. Negative feedback loops are a key mechanism in homeostasis, where the body detects a change in a certain variable and activates mechanisms to reverse or counteract that change, bringing the variable back to its set point. This helps maintain stability and balance in the body. Positive feedback loops, on the other hand, amplify or reinforce a change, which is not conducive to maintaining homeostasis. "Brain loop" is not a recognized term or concept in relation to homeostasis.Rate this question:

The "cause" for something to happen is the
- A.
Stimulus
- B.
Response
- C.
Effect
Correct Answer
A. StimulusExplanation
The "cause" for something to happen is the stimulus. A stimulus is an event or action that triggers a response or reaction. It can be any external or internal factor that influences or provokes a change in behavior, physiology, or thought process. In this context, the stimulus is the initial factor that sets off a chain of events leading to a specific outcome or effect.Rate this question:

What is the evaporation of a liquid to cool the body?
- A.
Sweating
- B.
Shivering
- C.
Breathing
Correct Answer
A. SweatingExplanation
Sweating is the correct answer because when our body temperature rises, the sweat glands release sweat onto the skin's surface. As the sweat evaporates, it absorbs heat from the body, cooling it down. This process helps regulate our body temperature and prevent overheating. Shivering is a response to cold temperatures, not to cool the body. Breathing does not directly contribute to cooling the body.Rate this question:

Homeostasis is maintaining a stable external environment
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Homeostasis is actually the ability of an organism to maintain a stable internal environment, not external. This is achieved through various physiological processes that regulate body temperature, blood pH, and other factors to keep them within a narrow range.Rate this question:

Temperature, exercise, hydration, sugar levels, nourishment, and diseases all affect homeostasis.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because all the factors mentioned, such as temperature, exercise, hydration, sugar levels, nourishment, and diseases, can have an impact on the body's ability to maintain homeostasis. Homeostasis refers to the body's ability to regulate its internal environment and keep it stable despite external changes. These factors can disrupt the balance and trigger physiological responses to restore equilibrium. For example, if the body temperature rises, it will initiate sweating to cool down and maintain a stable temperature. Similarly, if blood sugar levels drop, the body will release hormones to increase glucose levels.Rate this question:

What happens to your body and homeostasis when you work out? Click all that are true
- A.
Muscles need more oxygen, so your heart beats faster increasing his heart rate, which pumps more blood, and then the blood delivers oxygen to the organs
- B.
You start to shiver to warm the body up
- C.
You start to sweat to cool the body down
- D.
The muscles get pumped from you pumping iron
Correct Answer(s)
A. Muscles need more oxygen, so your heart beats faster increasing his heart rate, which pumps more blood, and then the blood delivers oxygen to the organs
C. You start to sweat to cool the body downExplanation
When you work out, your muscles need more oxygen to meet the increased demand for energy. As a result, your heart beats faster, increasing its heart rate. This increased heart rate pumps more blood, which delivers oxygen to the organs in your body. Additionally, as your body temperature rises during exercise, you start to sweat in order to cool down.Rate this question:

Diabetes is a disease where sufferers cannot control their blood glucose levels.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Diabetes is a chronic medical condition characterized by the inability of the body to regulate blood glucose levels effectively. People with diabetes have high blood sugar levels because their body either does not produce enough insulin or does not use insulin properly. This lack of control over blood glucose levels is what defines diabetes as a disease. Therefore, the statement "Diabetes is a disease where sufferers cannot control their blood glucose levels" is true.Rate this question:

- A.
The increase the temperature of the body to kill the bacteria
- B.
To lower the temperature of the body to kill the bacteria
- C.
To make you feel miserable
Correct Answer
A. The increase the temperature of the body to kill the bacteriaExplanation
When the body develops a fever, it increases its temperature in order to kill the bacteria causing the sickness. Higher body temperatures can inhibit the growth and reproduction of bacteria, making it more difficult for them to survive and spread. Therefore, by raising the body's temperature, the immune system aims to eliminate the bacteria and restore health.Rate this question:

Maintaining homestasis is the difference between .... click all that apply
- A.
Life
- B.
Death
- C.
Cell transport
- D.
Diffusion
Correct Answer(s)
A. Life
B. DeathExplanation
Maintaining homeostasis is crucial for the survival and functioning of living organisms. It refers to the ability of an organism to maintain a stable internal environment despite external changes. Without the ability to maintain homeostasis, life would not be possible as the organism would not be able to regulate its body temperature, pH levels, or other vital functions. On the other hand, death occurs when homeostasis can no longer be maintained, leading to the cessation of vital bodily functions. Therefore, both life and death are directly related to the concept of maintaining homeostasis. Cell transport and diffusion, although important processes, are not directly related to the difference between life and death.Rate this question:
