The term "biological structure" refers to what?

• A. The arrangement or organisation of parts to form an organ or system
• B. The genome sequence
• C. The hormonal profile
• D. The brain's electrical activity

Answer: (A)

Biological structure is about how parts are arranged and organized to form a whole, such as an organ or a system. It refers to the physical makeup of an organism—the anatomy from cells and tissues up to organs and body systems and how these parts fit together. This is different from the genome sequence, which is the genetic code; from the hormonal profile, which reflects biochemistry and signaling levels; and from brain electrical activity, which shows neural function rather than how parts are physically organized. The option that describes the arrangement forming organs or systems best captures what is meant by biological structure.
