Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions, such as temperature and pH.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and waxes, which are important for energy storage, insulation, and making up cell membranes.

Front

What happens to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will lose water and shrink due to osmosis.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of the cell's genetic material.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division, often resulting from disruptions in the normal cell cycle.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, following the concentration gradient.

Front

What role do proteins play in the body?

Back

Proteins are essential macromolecules that perform a variety of functions, including acting as enzymes, hormones, and structural components of cells.
