Final answer:
The 3-letter word for an apple seed or the spots on a pair of dice is "pip". Seeds have various characteristics, but the term "pip" is specific to fruit seeds or dice spots.
Step-by-step explanation:
The 3-letter word for an apple seed or any of the spots on a pair of dice is "pip". When considering apple seeds, one can notice that their characteristics vary, such as seeds can be round or wrinkled, and seeds can have yellow or green cotyledons, with cotyledons referring to the tiny leaves inside the seeds. However, the term "pip" specifically refers to the small seed of a fruit, like an apple, or the spots on dice or dominoes.
In the context of a pair of dice, each dot is known as a pip. On typical six-sided dice, the arrangement of pips indicates the numbers one through six. For example, if a die shows one pip in the center, that represents the number one. The six pips on a die are typically arranged in three pairs of two, forming a pattern that is easy to recognize.
