Science Homeostasis

What is cellular homeostasis?

• The process by which cells divide and reproduce.

• The ability of cells to communicate with each other.

• The process by which cells convert nutrients into energy.

• The ability of cells to maintain a stable internal environment despite external changes.

Why is cellular homeostasis important for living organisms?

• Cellular homeostasis is not important for living organisms.

• Cellular homeostasis only affects non-living organisms.

• Cellular homeostasis is important for living organisms because it allows cells to maintain an unstable internal environment.

• Cellular homeostasis is important for living organisms because it allows cells to maintain a stable internal environment, which is necessary for proper functioning and survival.

How does the respiratory system help in maintaining oxygen and carbon dioxide balance?

• By converting oxygen into carbon dioxide

• By filtering oxygen and carbon dioxide from the blood

• Through the process of respiration

• By producing oxygen and removing carbon dioxide

What are the consequences of disrupted homeostasis in the body?

• Imbalance, dysfunction, and deterioration

• Inflammation, infection, and disability

• Disease, organ failure, and death

• Malfunction, disorder, and decay

Explain the negative feedback loop involved in homeostasis.

• Negative feedback loop is a mechanism in which the body senses a change and amplifies that change to maintain homeostasis.

• Negative feedback loop is a mechanism in which the body ignores a change and allows it to persist, disrupting homeostasis.

• Negative feedback loop is a mechanism in which the body senses a change and activates processes to further enhance that change, disrupting homeostasis.

• Negative feedback loop is a mechanism in which the body senses a change and activates processes to reverse that change and restore homeostasis.
