The gene-directed process by which an organism matures.

The gene-directed process by which an organism matures.

• A. Evolution
• B. Hypothesis
• C. Theory
• D. Development

Answer: (D)

Development is the gene-directed process by which an organism matures. It encompasses growth, cell differentiation, and the shaping of tissues and organs, all guided by patterns of gene expression and signaling that tell cells when to divide, what to become, and how to organize into a functioning organism. This contrasts with evolution, which describes genetic changes in populations over many generations, not the maturation of a single individual. A hypothesis is a testable statement, and a theory is a well-supported broad explanation, but neither captures the idea of an individual mending and forming its mature form under genetic instructions in the way development does.
