If the surface is concave, or curved inward, a group of light rays from a distant source is reflected back toward a single location known […]

How do we hear pitch? Sound waves enter the outer ear (the pinna) and are sent to the eardrum via the auditory canal. There are two theories as to how we perceive pitch: The frequency theory of hearing suggests that as a sound wave’s pitch changes, nerve impulses of a corresponding frequency enter the auditory […]

How do humans affect the abiotic components in an ecosystem? Humans have also learned how to intentionally alter the abiotic factors of the environment. For instance, every time you turn on the air conditioning or sprinkle salt on a road to help snow melt, you are changing abiotic factors. Is human biotic or abiotic? Biotic […]
