Question
NASA’s Kepler mission found evidence of several potentially habitable exoplanets, raising the possibility that life may have evolved independently outside of our solar system. If NASA found a novel lifeform, we would expect it to use energy molecules based on similar principles as lifeforms on Earth. The organism would likely use molecules with _____________ bonds. It might use two separate molecules, one serving as a rapidly utilizable energy currency and another molecule serving as long-term energy storage A.high energy B.low energy C.hydrogen D.electrostatic
Explanation / Answer
D. Electrostatic bonds
electrovalent bond, ionic bond
bond, chemical bond - an electrical force linking atoms.
electrostatic bond - a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ionelectrovalent bond, ionic bond
bond, chemical bond - an electrical force linking atoms.
