What is the significance of genetically modified organisms (GMOs)?

Back

GMOs are organisms whose genetic material has been altered using genetic engineering techniques, often to enhance desired traits such as resistance to pests or improved nutritional content.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the mass of the reactants equals the mass of the products.
