Homeostasis is the process of keeping the body’s internal conditions, like temperature and oxygen levels, relatively constant so that cells can function properly.

What are some examples of large biomolecules made in the body?

Examples of large biomolecules include carbohydrates, lipids, and proteins.

What is the cell life cycle, and why is it important?

The cell life cycle includes cell growth and reproduction. It’s important because it allows the body to grow, repair, and pass on genetic information to new cells and future generations.

A tissue is a group of similar cells that work together to perform a common function.

What are the two main types of connective tissues that make up the skeleton?

The two main types are bone and cartilage.

What is an articulation, and what are its types of movement?

An articulation, or joint, is where two bones meet. Some joints allow a lot of movement, while others—like the sutures in the skull—are immovable or only allow limited motion.

Why is the movement of phospholipids and proteins in the membrane important?

Their movement keeps the membrane flexible and helps the cell control what enters and exits, communicate, and stay supported.

What is DNA and what is its main function?

DNA, or deoxyribonucleic acid, is the molecule that stores genetic information and provides instructions for building proteins and controlling traits.

What is the difference between negative and positive feedback in homeostasis?

Negative feedback reverses a change to bring the body back to normal (like sweating to cool down), while positive feedback strengthens a change (like stronger contractions during labor).

What are the three main layers of the skin?

The three main layers of the skin are the epidermis, dermis, and subcutaneous tissue (hypodermis).
