SBI3U unit 1 review Question and
answer already passed 2025
What is a species? - correct answer A group of similar organisms that can
breed and produce fertile offspring.
What is hybridization? - correct answer When two species breed and produce
a cross under natural conditions (a horse and a donkey create a mule).
What is morphology? - correct answer A branch of biology that studies the
external and internal structured of living things.
What is taxonomy? - correct answer The branch of biology concerned with
classification of organisms. A system of organisation through which individual
species can be grouped together based on shared characteristics and
lineages.
What is binomial nomenclature? - correct answer Biological system of naming
organisms where the name is composed of the genus and the species.
What is a taxon? - correct answer A group or level of organisation into which
organisms are classified.
What is a dichotomous key? - correct answer An aid that is used to identify
organisms and that consists of the answers to a series of questions.
Who developed taxonomy and when? - correct answer It was created by
Swedish Botanist Carl Linnaeus in 1735.
,What are the seven levels (taxa) in taxonomy? - correct answer Kingdom,
Phylum, Class, Order, Family, Genus, Species.
How do you name an organism using binomial nomenclaure? - correct answer
You use two terms: the genus and the species. For example "homo sapien."
What is phylogeny? - correct answer The science that deals with evolutionary
relationships among a set of taxa.
What is a phylogenic tree? - correct answer Branching diagram that
represents relationships between taxa, similar to a cladogram
What is a clade? - correct answer A taxonomic group that includes a single
ancestor species and all its descendants.
What is evolution? - correct answer Change over time in a certain direction,
when something evolves.
What is a prokaryote? - correct answer Organisms whose cells lack a nucleus
and other organelles. Divided into bacteria and archaea.
What is a eukaryote? - correct answer Organisms whose cells contain a
nucleus and other membrane-bound organelles.
What is a domain? - correct answer The largest of all taxonomic groups.
What are the three domains? - correct answer Archaea, Bacteria, Eukarya.
, What are the six kingdoms? - correct answer Eubacteria, Archaebacteria,
Protista, Fungi, Plantae, Animalia.
What is a cladogram? - correct answer A branching diagram which shows the
key evolutionary relationships between the six kingdoms.
What is a pathogen? - correct answer Any disease causing agent.
What are organic chemicals? - correct answer Compounds containing both
carbon and hydrogen atoms.
What are inorganic chemicals? - correct answer A chemical that does not
contain carbon and is not associated with life.
What is binary fission? - correct answer A form of asexual reproduction in
which one cell divides to form two genetically identical cells.
What is conjugation? - correct answer One bacterial cell transfers some
genetic material to another bacterial cell through direct physical contact.
Typically involving a specialised structure called a pilus.
What is transformation? - correct answer The process by which bacteria can
take up and incorporate foreign DNA from surroundings into their own genetic
material.
What is an endospore? - correct answer A highly resistant structure that
forms around the chromosome when the cell is under stress.
What are the six kingdoms of life? - correct answer Eubacteria,
Archaebacteria, Protista, Fungi, Plantae, Animalia.
