Ecosystem resilience relies on
maintaining biodiversity in order to
be sustainable and productive.
Conservation strategies are
required to overcome
environmental challenges—natural
or human induced.
Conservation
 rationale for the effective
conservation of biodiversity
within natural ecosystems
 conservation projects and
strategies for maintaining
biodiversity and the prevention
of extinction including:
o genetic e.g. gene/seed banks,
captive breeding programs,
DNA profiling, development of
new strains
o environmental e.g.
reafforestation, introduced
species, pest control
o management e.g. national
parks, protected zones,
licences, open seasons.
116–136
466–469
Continuity of species
DNA is a self-replicating and
information-carrying molecule. The
manipulation of DNA has lead to a
range of applications of
biotechnology, particularly in
medicine, agriculture and
conservation. Individuals within a
species show variety in a range of
characteristics. Change in a
species, over time, is due to the
selection of inheritable
characteristics best suited to the
environment.
DNA
 replication of DNA
 cloning and genetic modification
of organisms.
 protein synthesis
171–174

463–464
Recombinant DNA techniques
 recombinant DNA technology
o use of probes
o restriction and ligase
enzymes
o vectors and bacterial
plasmids.
465–472
261–266
247–256
Applications of DNA
technologies
 genetic modification of organisms
 recombinant DNA technology and
DNA identification technology in
o agriculture
o environmental conservation
o pharmaceuticals.

Variation
 significance of meiosis
 sources of variation including
o gene mutation
o the independent assortment
of chromosomes
o crossing over during meiosis
o random mating.

Selection
 process of natural selection
leading to change in
characteristics of a population e.g.
pesticide resistance
 selective pressures leading to
change or extinction e.g. loss of
habitat, predation
 practical application of artificial
selection e.g. the selective
breeding of animals and crops.
574–580
Speciation/evolution
 gene pools
 changes in allele frequency due
to:
o natural selection
o sexual selection
o the founder effect
o genetic drift.
583–590
Evidence for evolution
 evolutionary relationships
between groups using
physiological, molecular and
genetic features in phylogenetic
trees
 evidence for evolution including:
o fossils
o homologous structures
o comparative anatomy
o embryology of vertebrates
o comparative biochemistry and
genetics.

Working as a biologist
Planning and conducting ethical
biological research
 designing an investigation for a
hypothesis developed from the
research area
 devising a safe investigation
involving a number of variables
 microscopy techniques
 standard scientific techniques
and SI units
 critique of a published reviewed
biological sciences study
Evaluating and communicating
as a biologist
 environmental and ethical
considerations associated with
practices of biotechnology
 limitations of design
 implications and issues
associated with the possible
application of their findings
 defending or debating findings
 challenging others’
interpretations of data, using
evidence and biological
knowledge
 reflecting on own beliefs and
that of others in the light of
evidence
 influence of biological research
on decision-making and
management of biological
systems
 implications for careers and
commercial applications of
biological research
