Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions without being consumed in the process.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where the solute is completely dissolved in the solvent, while a mixture can be heterogeneous.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.
