The scientific name for a species has how many parts? (a)
A common ancestor and all its descendants make up a (a)
The members of which domain are most apt to live in harsh habitats, such as brine pools or volcanic hot springs?
Archaea
Bacteria
Eukarya
Monera
Which cell structure distinguishes members of domain Eukarya from other organisms?
cell wall
cell membrane
cytoplasm
nucleus
Which is an example of binomial nomenclature in the Linnaean system of taxonomy? (a)
System of naming and classifying organisms based on shared characteristics and universal rules (a)
A young child classifies animals into 26 groups according to the alphabet. For example, the first group of animals in this scheme includes ants, antelope, apes, and other animals that have common English names beginning with the letter A.
How do the taxa that scientists use to classify animals differ from the child’s classification scheme?
Taxa are based on Latin, not English.
Taxa are based on biological relationships, not language.
Every taxon contains exactly the same number of members.
Every taxon contains a wide variety of organisms, not just animals.
Scientists now classify all living things into 6 kingdoms. Which of the following groups of organisms is classified into the greatest number of kingdoms?
multicellular animals that are larger than humans
humans and other multicellular organisms that are about the same size as humans
plants and animals that are smaller than humans but still visible
organisms that are microscopically small and each made of a single cell
The domain is a relatively new taxonomic category. Which statement best explains why scientists added the domain to the Linnaean classification system?
A prokaryotic cell lacks a nucleus, while a eukaryotic cell has a nucleus.
The two groups of prokaryotes differ greatly from each other and from eukaryotes
All prokaryotes are single celled, while many eukaryotes are multicellular.
Prokaryotic cells are much smaller than eukaryotic cells.
Members of domain Archaea and domain Bacteria share many characteristics. In which characteristic are archaea different from bacteria?
Cell organization, because archaea are single-celled.
Cell structures, because archaea use different types of cell walls and cell membranes
Size, because archaea are too small to be observed without a microscope.
Presence of a nucleus, because archaea are prokaryotic.
Scientists now use domain Eukarya to group together the kingdoms of eukaryotic species, which include plants, animals, protists, and fungi. Which statement about the evolution of eukaryotes supports the grouping of the kingdoms into domain Eukarya?
All eukaryotic species descended from a common eukaryotic ancestor.
Each eukaryotic kingdom descended from a unique prokaryotic ancestor.
Species in the four eukaryotic kingdoms evolved independently of one another.
Protists evolved first, then the fungi appeared, and then plants and animals.
Which property describes members of kingdom Animalia, but not the members of the kingdom Plantae?
cell walls made of cellulose
cell walls made of chitin
heterotrophic
autotrophic
Which characteristic applies to all four eukaryotic kingdoms: Protista, Fungi, Plantae, and Animalia?
cells without nuclei
cells with uniform, sphere-like shapes
cells with DNA stored in the cytoplasm
cells with nuclei and other membrane-bound organelles
A group of closely related species; the first part of the scientific name in binomial nomenclature (a)
The study of the evolutionary history of lineages of organisms is known as
a genus
binomial nomenclature
phylogeny
systematics
The largest taxon is called (a)
Which kingdom or kingdoms have only heterotrophs?
Eubacteria
Archaebacteria
Protisa
Fungi
