Answer the following question given this paragraph: An electron is a particle outside the nucleus of an atom that has a negative electric charge. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. As a result, the negative and positive charges "cancel out. " This makes atoms electrically neutral. For example, a carbon atom has six electrons that "cancel out" its six protons. Q: What is the term for a particle outside the nucleus of an atom that has a negative electric charge? Choices: - proton - ion - neutron - electron A:

Answer the following question given this paragraph: The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. Ironically, the deadly effects of gamma rays can be used to treat cancer. In this type of treatment, a medical device sends out focused gamma rays that target cancerous cells. The gamma rays kill the cells and destroy the cancer. Q: What enables gamma rays to pass through hard matters like bones, teeth, and just about anything? Choices: - Weight - Being Heavier - Density - their extremely high energy A:
(A).
their extremely high energy
