Developmental biology focuses on what?

• A. Focuses on the genetics of inherited diseases only
• B. Focuses on the ecological relationships between species
• C. Focuses on the study of change during the cycle of life from conception to death
• D. Focuses on the anatomy of adult organ systems

Answer: (C)

The main concept being tested is what developmental biology studies: the changes organisms undergo from conception through the rest of life. It covers how cells divide and differentiate, how tissues and organs form (morphogenesis), and how gene regulation and signaling guide these developmental processes. For example, it looks at how an embryo’s cells become bone, muscle, or nerve tissue and how those patterns create a functioning organism, as well as how development progresses and changes later in life. This field isn’t limited to genetics of inherited diseases, nor is it about ecological relationships or just the anatomy of adult organ systems; it focuses on growth, development, and aging from fertilization onward.
