Answer the following question given this paragraph: The light reactions occur in the first stage of photosynthesis. This stage takes place in the thylakoid membranes of the chloroplast. In the light reactions, energy from sunlight is absorbed by chlorophyll. This energy is temporarily transferred to two molecules: ATP and NADPH. These molecules are used to store the energy for the second stage of photosynthesis. The light reactions use water and produce oxygen. Q: Light reactions occur during which stage of photosynthesis? Choices: - intermediate stage - third stage - final stage - first stage A:
first stage

Ques:Answer the following question given this paragraph: A liquid is a form of matter that has a definite volume, but an indefinite shape. As water is poured from one container into another, it adopts the shape of its new container. However, the volume of the water does not change, because the water molecules are still relatively close to one another in the liquid state. Unlike a solid, the arrangement of particles in a liquid is not rigid and orderly. Liquids are also incompressible. Q: What is a form of matter that has a definite volume, but an indefinite shape? Choices: - a solid - a plasma - a gas - a liquid A:

Ans:a liquid
