The distinction between protostomes and deuterostomes is based on differences in their?

The distinction between protostomes and deuterostomes is based on differences in their embryonic development.

This difference in early development leads to distinct patterns of development in the two groups.


Why is it possible to draw a distinction between natural substances and chemical substances?

The distinction between natural substances and chemical substances lies primarily in their origins and compositions. Natural substances are typically derived from nature and consist of complex mixtures of various compounds, such as minerals, plants, and animals. In contrast, chemical substances are often synthesized or purified through chemical processes in laboratories, resulting in specific compounds with defined chemical structures. This distinction highlights the differences in their sources, complexity, and the methods used to obtain or create them.
