AQA Biology Paper 2 EXAM LATEST 2026-2027
QUESTIONS AND 100% Verified ANSWERS
Artificial splitting of an early embryo which results in several clones who have the same mix of parental
traits - answer>>embryo cloning
Process in which the nucleus of an adult cell of one animal is fused with an empty egg from another
animal. The embryo which results is placed inside the uterus of a third animal to develop. -
answer>>adult cell cloning
A highly precise type of genetic engineering in which DNA is inserted, deleted or replaced in the genome
of an organism using engineered nucleases - answer>>gene editing
Branch of study of moral issues, questions, & problems arising in the practice of medicine & biological
research - answer>>bioethics
- answer>>b15
Characteristics determined by just one pair of alleles - answer>>monohybrid inheritance
Assisted by Rosalind Franklin's X-ray diffraction DNA images, they discovered the double-helix structure
of DNA molecules - answer>>James Watson and Francis Crick
Crystallized DNA to make an x-ray pattern. Showed an "x" shape, leading scientists to the idea that DNA
had a helix shape. - answer>>Rosalind Franklin and Maurice Wilkins
He proposed that by selective use or disuse of organs, organisms could acquire or lose certain traits
which are then passed on to their children and future generations, eventually changing the species -
answer>>Jean-Baptiste Lamarck
,English naturalist. He studied the plants and animals of South America and the Pacific islands, and in his
book On the Origin of Species by Means of Natural Selection (1859) set forth his theory of evolution. -
answer>>Charles Darwin
A process typically caused by environmental pressures and the genetic isolation from a main population
resulting in a new genetically distinct species. - answer>>speciation
English naturalist who proposed, independently of Charles Darwin, the concept of natural selection as a
mechanism for evolution and as a way to explain the great variety of living things - answer>>Alfred
Russell Wallace
The trace or remains of an organism that lived in the geological past, most commonly preserved in
sedimentary rock - answer>>fossil
A term that typically describes a species that no longer has any known living individuals. -
answer>>extinction
Develops when an antibiotic fails to kill all of the bacteria it targets; therefore, the bacteria becomes
resistant to that particular drug. When more and more bacteria become resistant to first-line
treatments, the consequences are severe - answer>>antibiotic resistant bacteria
Methicillin resistant staphylococcus aureus; an infectious disease caused by a pathogen that is resistant
to many antibiotics - answer>>MRSA
In biology, the ordering of organisms into categories, such as orders, families, and genera, to show
evolutionary relationships. - answer>>classification
A taxonomic category, the second broadest after domain. - answer>>kingdom
A taxonomic category above the kingdom level. The three are Archaea, Bacteria, and Eukarya. -
answer>>domain
, Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan -
answer>>archaea
Kingdom of unicellular prokaryotes whose cell walls are made up of peptidoglycan - answer>>eubacteria
A system for giving each organism a two-word scientific name that consists of the genus name followed
by the species name - answer>>binomial nomenclature
A Swedish botanist, physician, and zoologist, who laid the foundations for the modern biological naming
scheme of binomial nomenclature. He is known as the father of modern taxonomy, and is also
considered one of the fathers of modern ecology. - answer>>Carl Linnaeus
Did King Phillip Come Over For Good Soup? Domain Kingdom Phylum Class Order Family Genus Species.
- answer>>taxonomic hierarchy
Kingdom of unicellular prokaryotes whose cell walls do not contain peptidoglycan -
answer>>archaebacteria
Domain of unicellular prokaryotes that have cell walls containing peptidoglycan - answer>>Bacteria
Domain of organisms whose cells contain nuclei, includes animals, plants, fungi, and protists -
answer>>Eukaryota
A kingdom of unicellular living organisms that are neither animals, plants nor fungi; includes some
groups of algae, slime molds and protozoa; cells contain nuclei - answer>>Protista
The classification kingdom containing complex, multicellular organisms that lack cell walls, are usually
able to move around, and possess specialized sense organs that help them quickly respond to their
environment - answer>>Animalia
