What is homeostasis, and why is it important in the human body?

Homeostasis is the body's ability to maintain a stable internal environment. It is important because it allows cells and organs to function properly.

What are the four major types of biomolecules and their primary functions?

Carbohydrates (energy), proteins (structure & enzymes), lipids (energy storage & membranes), nucleic acids (genetic information).

What is the function of the mitochondria in the cell?

Mitochondria are the "powerhouses" of the cell. They produce energy in the form of ATP through cellular respiration.

What is the difference between growth and development in biology?

Growth is an increase in size or number of cells, while development is a change in form and function as an organism matures.

What are the four main types of tissues in the human body?

Epithelial, connective, muscle, and nervous tissues.

What is the primary function of the skin?

The skin protects the body from pathogens, regulates temperature, and prevents water loss.

What is the main difference between compact and spongy bone?

Compact bone is dense and provides strength, while spongy bone is lighter and contains red bone marrow for blood cell production.

Name the two major divisions of the human skeleton.

The axial skeleton (skull, spine, ribcage) and the appendicular skeleton (limbs and girdles).

What type of joint allows for the greatest range of motion, and give an example.

Ball-and-socket joints, such as the shoulder or hip
