Obviously, clerical temps need to be proficient in at least basic office skills. They should be able to type, whether on a typewriter or a computer keyboard, and produce documents that are free of typographical, spelling and grammar errors. Although many positions do not require 10-key skills, others do, so 10-key proficiency is desirable.
A. Scientific theories are proposed answers to questions. B. Scientific theories are never proven. C. Scientific theories become hypotheses. D. Scientific theories summarize patterns found in nature. Weegy: The TRUE statement about scientific theories is : Scientific theories are never proven.
Examples are, plate tectonics, evolution, gravity, atomic theory, the germ theory of disease, relativity, quantum theory, electromagnetic theory, layered Earth theory, etc. It's statement (d), of course! Because if a scientific theory could never be proven, that wouldn't be a theory, would it. Scientific laws...if by laws you mean the law of gravity or Coulomb's law of charge...whatever, then (a) is also partially true. (c) just sounds ridiculous because it's actually the reverse that happens.
