Chapter 18 section assessments and chapter review
Companions to photographed 18-1, 18-2 and 18-3 section questions. Use these for existing classwork and C18 review; no new due date is inferred.
18-1 · Finding order
Use naming conventions and kingdom → phylum → class → order → family → genus → species. Names help people identify the same organism despite differing common names.
18-2 · Evolutionary classification
Compare relationships using inherited derived traits and DNA evidence. Read branch points. A molecular clock uses inherited mutations to estimate separation time.
18-3 · Kingdoms and domains
Compare cell type, cell number and nutrition. Use the six-kingdom model taught in class: Eubacteria, Archaebacteria, Protista, Fungi, Plantae and Animalia. Domains are Bacteria, Archaea and Eukarya.
