Hi lovely,
Are you able to provide me with your answer choices?
Living things are based on a universal genetic code. All organisms store the complex information they need to live, grow, and reproduce in a genetic code written in a molecule called DNA. That information is copied and passed from parent to offspring and is ALMOST identical in every organism on Earth.
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
