Final answer:
The prefix 'mono-' denotes 'one'. It is used across various disciplines, including English and chemistry, to indicate singular elements in compound words. Understanding prefixes such as 'mono-' is essential for vocabulary development and word analysis. The correct option is A.
Step-by-step explanation:
The prefix mono- means 'one'. The application of the prefix mono- can be seen in various words to denote a single unit or element, like 'monologue' (a speech by one person) or 'monochrome' (a picture in shades of one color). It is important to understand prefixes as they help determine the meaning of the compound word they form when joined with a base word or stem.
In chemistry, the prefix mono- is used to indicate one atom of a single element, as in monoxide, which means one oxygen atom combined with another element.
When reviewing words with different prefixes, you would analyze each word by separating the prefix from the stem. For example, in the word 'disagree', 'dis-' is the prefix, and 'agree' is the stem. When a word starts with an s- and the prefix 'dis-' or 'mis-' is added, it results in a double 'ss' as in 'dissolve' or 'misstep'.
