What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

Front

What is aerobic respiration?

Back

Aerobic respiration is a biological process in which cells convert glucose and oxygen into energy, carbon dioxide, and water, producing more energy than anaerobic respiration.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a process of energy production that occurs in the absence of oxygen, resulting in less energy compared to aerobic respiration.

Front

Define mutualism in ecology.

Back

Mutualism is a symbiotic relationship between two different species where both parties benefit from the interaction.

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells build proteins based on the genetic instructions carried by mRNA.

Front

What role do ribosomes play in a cell?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of the yucca moth in relation to the yucca plant?

Back

The yucca moth pollinates the yucca plant while laying its eggs, ensuring cross-pollination and providing food for its larvae.

Front

What is the difference between aerobic and anaerobic respiration in terms of energy production?

Back

Aerobic respiration produces more energy (approximately 36-38 ATP) compared to anaerobic respiration, which produces only 2 ATP.

Front

What is the significance of concentration gradients in biological processes?

Back

Concentration gradients drive the movement of substances across membranes, influencing processes like osmosis and diffusion.

Front

What is the role of saltwater in reducing swelling in gums?

Back

Saltwater creates a hypertonic environment, causing water to move out of swollen gum tissues, reducing swelling.
