Question: What is homeostasis, and why is it critical for survival?

Homeostasis is the body's ability to maintain a stable internal environment despite external changes. It’s essential for survival because imbalance can lead to dysfunction or disease

What is hydrolysis, and why is it important in the body?

Hydrolysis is a decomposition reaction that breaks chemical bonds using water, essential for breaking down complex molecules like proteins and carbs during digestion.

As hydroxide ion (OH–) concentration increases, what happens to pH and acidity?

pH increases, and the solution becomes more basic (alkaline).

Definition: Specialized structures within a cell that perform specific functions (e.g., mitochondria for energy production, ribosomes for protein synthesi

What is the role of the plasma membrane in a cell?

It regulates what enters and exits the cell and helps maintain homeostasis by acting as a selective barrier.

What are the two main layers of the skin?

Epidermis (outer layer) and dermis (inner layer).

Term: Epithelial Tissue

Definition: Tissue that covers body surfaces, lines cavities, and forms glands. Functions include protection, absorption, and secretion.

What type of connective tissue makes up most of the skeleton?

Bone tissue (osseous tissue) and cartilage.

What are the two main divisions of the human skeleton, and what do they include?

• Axial skeleton: skull, vertebral column, and thoracic cage — supports and protects vital organs. • Appendicular skeleton: limbs and girdles (shoulder and pelvis) — enables movement.
