<h3>What is structure in biology?</h3>

A structure, according to biology, is an arrangement or organization of parts to form an organ, system, or living thing.

The structures found in living organisms are usually function-specific. Examples of common structures in living organisms and their respective functions are as follows:

  • Radula in snails - feeding
  • Eyespot in Euglena- light sensing
  • Claws in carnivores- for holding prey

Therefore, the statement that best represents how structure relates to function is as follows: a deer's horizontal pupils (structure) help it scan the horizon for predators (function).
