Which statement best describes Biodiversity?
The variety of living organisms in an area, including genetic, species and habitat diversity.
The role of a species within its habitat, including its biotic and abiotic interactions and resource use.
The scientific process of peer review and scrutiny used to validate new evidence, e.g. for changes to classification.
The proportion of a particular allele among all alleles of that gene in a population.
8.
Which statement best describes Speciation?
The formation of a new species when populations become reproductively isolated and evolve independently.
The proportion of a particular allele among all alleles of that gene in a population.
An inherited anatomical, physiological or behavioural feature that increases an organism's chance of survival and reproduction.
The role of a species within its habitat, including its biotic and abiotic interactions and resource use.
9.
Which statement best describes Allele frequency?
The variety of living organisms in an area, including genetic, species and habitat diversity.
The scientific process of peer review and scrutiny used to validate new evidence, e.g. for changes to classification.
The proportion of a particular allele among all alleles of that gene in a population.
The number of different species present in a habitat.
10.
Which statement best describes Gene pool?
