Front

What are the levels of organization in living organisms?

Back

The levels of organization in living organisms include: 1. Cells 2. Tissues 3. Organs 4. Organ systems 5. Organisms.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What are organic molecules?

Back

Organic molecules are compounds that contain carbon and are found in living organisms, such as carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the difference between positive and negative feedback loops?

Back

Positive feedback loops amplify a response or process, while negative feedback loops counteract a change to maintain stability.

Front

What is an example of a negative feedback loop in the human body?

Back

An example of a negative feedback loop is the regulation of body temperature: when body temperature rises, mechanisms like sweating are activated to cool the body down.

Front

What is differentiation in biology?

Back

Differentiation is the process by which unspecialized cells develop into specialized cells with distinct functions.

Front

What is the role of the extracellular matrix (ECM)?

Back

The extracellular matrix (ECM) provides structural and biochemical support to surrounding cells and plays a crucial role in tissue and organ function.

Front

What is a stimulus in biological terms?

Back

A stimulus is any change in the environment that can provoke a response from an organism.

Front

What is an effector in a feedback system?

Back

An effector is a component of a feedback system that carries out a response to a stimulus, such as muscles or glands.

Front

How do cells communicate with each other?

Back

Cells communicate through chemical signals, such as hormones and neurotransmitters, which bind to receptors on target cells.
