experiment, in the scientific method the hypothesis is tested through experimentation and if confirmed is called a theory.
The taxa under which the given plant fossil come is angiosperm.
<h3>What are taxa?</h3>
Taxa refer to any unit employed in the discipline of biological classification, often known as taxonomy. Taxa are organized in a hierarchical order, from kingdom to subspecies, with a particular taxon typically containing numerous taxa of lower rank.
Taxa are given formal names after being properly identified by nomenclature codes and systems. Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms are a few examples of major plant taxa.
Therefore, the taxonomic group from which the presented plant fossil is derived is angiosperm.

The given statement is true.
The majority of genes in the human beings are same and the variation lies in some point percentage. This small percentage causes a huge variation in the phenotype of the humans. The expression of gene is different in different individuals. The variation is very tiny though this little variation leads to a large phenotypic variation and makes one individual different from other.
