What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions, despite changes in the external environment.

What happens to plant cells when placed in saltwater?

Back

Plant cells will shrink because water will move out of them due to osmosis.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms, where carbon dioxide is converted into glucose.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil and organisms already exist, typically after a disturbance.

Why is reporting a sea turtle stranding important?

Back

Reporting a sea turtle stranding is important because the information can help biologists and managers protect the species and understand their health and population dynamics.

Front

What is excretion?

Back

Excretion is the process by which waste products are removed from the body of an organism.

Front

What is metabolism?

Back

Metabolism refers to all the chemical reactions that occur within a living organism to maintain life, including those that convert food into energy.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed for photosynthesis, allowing plants to convert carbon dioxide and water into glucose and oxygen.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, initiating the process of ecological succession.

Front

What is osmosis?

Back

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