Question

during osmosis
water moves from high to low concentration.
large or oddly shaped molecules move across a cell membrane.
water moves when energy is used.
proteins are built.

Explanation:

Osmosis is a process in Biology (a subfield of Natural Science) where water moves across a semi - permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration). Let's analyze each option:

• Option 1: "water moves from high to low concentration" matches the definition of osmosis.
• Option 2: Large or oddly shaped molecules moving across a cell membrane is more related to processes like facilitated diffusion or active transport for larger molecules, not osmosis.
• Option 3: Osmosis is a passive transport process, which means it does not require energy. So this option is incorrect.
• Option 4: Protein synthesis is a completely different cellular process and has nothing to do with osmosis.

Answer:

A. water moves from high to low concentration.
