Question
Chapter 28.3, Problem 2EQ
Summary Introduction
To explain: The reason that boiling in concentrated acid is a reasonable way to investigate the presence of biological materials that may resist decay long enough to form fossils.
Introduction: Cladophora is a species of green algae. It has the capacity to perform photosynthesis. This green alga is generally found near aquatic areas such as the ocean. A unique feature is observed in this alga that is it is not attacked by microbes. It is protected by the microbial attack. The scientist worked to discover the reason that Cladophora is resistant to microbial attack.
