What do we call the changes that occur in an organism as it grows?

• A. Adaptation
• B. Development
• C. Reproduction
• D. Metamorphosis

Answer: (B)

The changes that occur in an organism as it grows are referred to as development. This process encompasses all the physical and biological changes that an organism undergoes from the time it is conceived until it reaches maturity. Development includes processes like cell division, growth, and differentiation, allowing the organism to attain its adult form.

Adaptation, on the other hand, refers to changes that enhance an organism's ability to survive in its environment over generations, which is distinct from the changes that happen within a lifetime of an individual organism. Reproduction pertains to the biological process through which new individuals are produced, but it does not describe the growth process of an existing organism. Metamorphosis is a specific type of development seen in certain animals, such as frogs and insects, where the organism undergoes a dramatic transformation, but it is not a general term that applies to all organisms as they grow. Therefore, development accurately describes the overall changes that happen as an organism matures.
