Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment in an organism, often incorporating feedback regulation.

Front

What happens to blood cells in a hypertonic solution?

Back

In a hypertonic solution, blood cells shrivel (shrink) due to the loss of water.

Front

What is the role of pulse rate during exercise?

Back

Pulse rate increases during exercise to facilitate faster gas exchange and transport of oxygen and carbon dioxide.

Front

What is an example of a behavior that is NOT homeostasis?

Back

A human producing gametes is NOT an example of homeostasis.

Front

Why is thirst important for homeostasis?

Back

Thirst is important because it signals the need to replace water removed by the kidneys.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing the cell to swell.

Front

What is a feedback regulation in homeostasis?

Back

Feedback regulation is a process where the output of a system influences its own operation, helping to maintain stability.

Front

How do plants maintain homeostasis?

Back

Plants maintain homeostasis by adjusting their water intake and orientation towards sunlight.

Front

What is the significance of gas exchange in homeostasis?

Back

Gas exchange is crucial for maintaining oxygen levels and removing carbon dioxide, which is vital for cellular function.

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.
