Final answer:
The suffixes that mean "two" are "dipl-" and "bi-". Examples include diplomacy and bicycle, which use these prefixes to indicate the concept of two. In chemistry, "di-" and "bis-" also indicate two, as in dioxide and bis(bipyridyl)osmium(II).
Step-by-step explanation:
The suffixes that mean "two" are "dipl-" and "bi-". Therefore, the correct answer to which of the following suffixes mean "two" is A. "dipl-" and "bi-".
Examples:
- dipl-: Diplomacy (where 'dipl-' comes from Greek 'diplous,' meaning double)
- bi-: Bicycle (where 'bi-' means two, as in two wheels)
The prefix "di-" is also commonly used to indicate two, especially in chemistry. For instance, in a chemical name such as 'dioxide,' 'di-' specifies that there are two oxygen atoms. Similarly, 'bis-', a variant of 'bi-', is used to indicate two, primarily in coordination chemistry, where it avoids confusion with other prefix meanings and aids in clarity, as seen in 'bis(bipyridyl)osmium(II)'.
