What is homeostasis?

Back

Homeostasis is the tendency of an organism to maintain a stable internal environment despite changes in external conditions.

Front

What process does organelle X perform if it is responsible for cellular respiration?

Back

Organelle X, likely the mitochondria, performs cellular respiration, which is the process of converting glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are feedback mechanisms?

Back

Feedback mechanisms are processes that help maintain homeostasis by responding to changes in the internal environment, such as temperature regulation through blood vessel dilation and sweating.

Front

What is aerobic respiration?

Back

Aerobic respiration is a metabolic process that requires oxygen to convert glucose into energy (ATP), carbon dioxide, and water.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy through aerobic respiration.

Front

What is the difference between homeostasis and stimuli?

Back

Homeostasis refers to the maintenance of a stable internal environment, while stimuli are changes in the environment that can provoke a response from an organism.

Front

What is the significance of sweat glands in temperature regulation?

Back

Sweat glands help cool the body by excreting sweat, which evaporates and lowers body temperature, a key aspect of maintaining homeostasis.

Front

What is the definition of cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the importance of maintaining a balanced state in organisms?

Back

Maintaining a balanced state, or homeostasis, is crucial for the health and proper functioning of organisms, allowing them to survive in varying environmental conditions.

Front

What is the role of blood vessels in thermoregulation?

Back

Blood vessels can dilate or constrict to regulate blood flow and heat loss, helping to maintain body temperature.
