Answer
48) protons
49) covalent
50) decomposition; decomposition
51) bases
52) cytosine
53) ATP
54) Potential energy is stored energy from an object's position or condition, while kinetic energy is energy from motion.
55) False. All atoms have a nucleus with protons and electrons orbiting around it; hydrogen’s nucleus has only a proton.
Solution
48) protons
49) covalent
50) decomposition; decomposition
51) bases
52) cytosine
53) ATP
54) Potential energy is stored energy based on an object’s position or condition (for example, an object held at a height), whereas kinetic energy is the energy of motion (energy an object has when it is moving).
55) False. All atoms have a nucleus that contains protons (and usually neutrons), while electrons orbit the nucleus; no atom’s nucleus contains electrons, even hydrogen’s nucleus, which consists of a single proton.

Think of a drawn bow (potential) versus an arrow flying through the air (kinetic)! 55) False; hydrogen is unique because it only has one proton and no neutrons in its nucleus, making it the simplest atom. Protons and neutrons are found in the nuclei of all other atoms.
