Given a scientific passage and an answer, generate a question for the given answer.

Passage: Condensation reactions are the chemical processes by which large organic compounds are synthesized from their monomeric units. Hydrolysis reactions are the reverse process. During condensation reactions, water is produced from the two molecules being bonded together; an H from one monomer is joined to an -OH from another molecule, producing H 2 O. Answer: water
What is produced during a condensation reaction?

Passage: To harness water power, a stream must be dammed. Narrow valleys are the best for dams. While sitting in the reservoir behind the dam, the water has potential energy. Water is allowed to flow downhill into a large turbine. While flowing downhill, the water has kinetic energy. Kinetic energy makes the turbine spin. The turbine is connected to a generator, which makes electricity. Answer: kinetic energy
Water is allowed to flow downhill into a large turbine to harness power. what helps the turbine spin?

Passage: Cells are organized into tissues, and tissues form organs. Answer: cells
Tissues are organized by what?
