What type of feedback system reverses a change in a controlled condition?

Which body structure monitors changes in a controlled condition and sends input to a control center in a feedback system?

What does a positive feedback system tend to do to a change in one of the body’s controlled conditions?

Which component of a feedback system produces a response that changes the controlled condition?

Organs are composed of only one type of tissue.

Homeostasis is a self-regulating process by which biological systems maintain stability.

A vital organ not functioning can never result in death.

Cells are composed of water, inorganic ions, and carbon-containing molecules at the tissue level.

The chemical level of structural organization consists of subatomic particles like protons, electrons, and neutrons.

Homeostasis refers to a state of internal balance maintained by the body, while homeostatic imbalance indicates a disruption in this balance.

In a positive feedback system, the response reverses the stimulus.

Homeostasis is maintained when body cells function inefficiently.

Moderate homeostatic imbalance can lead to death.

Disease is a less specific term compared to disorder.

Vital organs are structures composed of only one type of tissue.

Homeostasis in the human body is a static condition that never changes.

Moderate homeostatic imbalance always leads to death.

The chemical level of structural organization consists of four sub-levels.

Homeostatic imbalances can only occur at the tissue level of structural organization.

In homeostasis, cells are primarily composed of inorganic ions like sodium and potassium.

In a negative feedback system, the response enhances or intensifies the stimulus.

Homeostatic imbalance always leads to the occurrence of a disease.

Cells are the smallest level of structural organization in the human body.

A fluctuation in maintaining equilibrium within the body is a characteristic of homeostasis.
