Answer 1

Answer:

1. d) Phylogenetic classification is based on common evolutionary descents.
2. d) Division, Class, Order, Family, Genus, Species

Explanation:

Phylogenetic classification is the process of grouping organisms into convenient categories based on common evolutionary characters between the organisms. This type of classification is used to study the relationships among the organisms. These are expressed as phylogenetic trees.

Taxonomy is a process of classification of living organisms into different taxa based on characteristics. Taxa are the scientific term for categories. It represents a rank of classification. Category, species is the very basic level, it includes organisms with fundamental similarities. The genus includes a group of related species. The family includes groups of related genera with less number of similarities. The order has groups of related families. class includes related orders. The division includes related classes. It is also termed a phylum.
