They also produce toxins that may poison predators that try to eat them. Choices: - sea floor - sand - beaches - reef or rock A:
reef or rock

Q: Solutions to schrodinger's equation involve four special numbers called what? Read this paragraph and choose the correct option from the provided answers: Solutions to Schrodinger's equation involve four special numbers called quantum numbers . (Three of the numbers, , , and , come from Schrodinger's equation, and the fourth one comes from an extension of the theory). These four numbers completely describe the energy of an electron. Each electron has exactly four quantum numbers, and no two electrons have the same four numbers. The statement that no two electrons can have the same four quantum numbers is known as the Pauli exclusion principle . Choices: - gravity numbers - linear numbers - light numbers - quantum numbers A:
quantum numbers
