Explain how phylogeny, classification, taxonomy, and binomial nomenclature are all related.

Taxonomy is the study of the classification of organisms. Taxonomists study the characteristics of organisms in order to classify them into the appropriate taxonomic groups, such as kingdom, phylum, class, etc.
Binomial nomenclature is a system of naming a species using two names, the genus and the species (and sometimes subspecies), which make up the scientific name of a species. Examples include Panthera tigris for the tiger, and Canis lupus for the gray wolf.
Phylogeny, or phylogenetics, is the study of the evolutionary development of organisms and relationships between them. Phylogeny is a useful tool for taxonomists.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
