Front

What is homeostasis?

Back

Homeostasis is the process by which a cell or organism maintains a stable internal environment despite changes in external conditions.

Front

How do cells maintain homeostasis?

Back

Cells maintain homeostasis by regulating what enters and leaves the cell, ensuring a balance of nutrients, ions, and water.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

Front

What is the role of energy in active transport?

Back

Active transport requires energy to move substances against their concentration gradient, from areas of lower concentration to higher concentration.

Front

What factors can increase the carrying capacity of an ecosystem?

Back

Factors that can increase carrying capacity include an increase in available food, water, and suitable habitat.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can sustainably support.

Front

What are lipids?

Back

Lipids are a group of organic compounds that are insoluble in water, including fats, oils, and waxes, and are important for energy storage and cell structure.

Front

What is the function of cell membranes?

Back

Cell membranes protect the cell, provide structure, and regulate the movement of substances in and out of the cell.

Front

What is osmosis?

Back

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

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of substances during diffusion.
