What is the rapid transformation of a larva into an adult observed in some animals?

1. any of the small solid extraterrestrial bodies

2. the marked transformation of a larva into an adult

3. the remains of a meteoroid that reached the earth's surface

4. a substance consisting of two or more substances mixed together

The correct answer is: the remains of a meteoroid that reached the earth's surface

The correct answer pertains to the transformation process known as metamorphosis, which specifically refers to the marked transformation of a larva into an adult. This biological phenomenon is observed in various species, including insects like butterflies and amphibians like frogs. During metamorphosis, the organism undergoes significant physical changes that enable it to transition from one life stage to another, often resulting in a completely different form and function in adulthood compared to the larval stage. In the context of the other options provided, they do not relate to this biological process. The first option references extraterrestrial bodies, which is not connected to animal development. The third option refers to meteoroids, which again has no relevance to the transformation of life stages in animals. The fourth option discusses mixtures of substances, unrelated to the concepts of organism development or life cycles. Each of these distracts from the core concept of metamorphosis, highlighting the distinct nature and significance of the rapid transformation that occurs in some animals.
