Final answer:
The prefix meaning "above" can be both Supra- and Hyper-, depending on the context.
Step-by-step explanation:
The correct prefix meaning "above" is both a) Supra- and b) Hyper-. These prefixes are used in various words in the English language to convey the meaning of being above or beyond the normal or usual level of something. For example, in words like supranational and hypersonic, the prefixes indicate being above the national level and the speed of sound, respectively.
For example:
Supra- is used in words like suprarenal, which refers to something situated above the kidneys. The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys.
Hyper- is often used in terms like hyperactive, which means abnormally or extremely active and can suggest 'above' normal activity levels.
