Answer 1

Hyo- is a root word referring to the hyoid bone. The word 'hyoid' is a bone name, and 'hyostyly' is a type of jaw structure in fish determined by the attachment to the hyoid bone.

Step-by-step explanation:

The root word hyo- is derived from Greek and means related to the hyoid bone in humans and mammals. For instance, the term hyoid refers to a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage which serves as an anchor for the tongue. The term hyostyly is a type of jaw suspension in fish, where the mandible is attached to the hyoid bone, which is in turn suspended from the skull. This type of jaw structure allows for a wide range of movements, contributing to feeding efficiency in various fish species.
