Organisms
The third rank in the classification system

9 of 32
Characteristics
Features that an organism has. these can be either unique to a species or unique to a larger group.

Prokaryotes
any cellular organism that has no nuclear membrane. (Bacteria and Blue-Green algae)
15 of 32
Vertebrates
Animals which have a backbone or spinal column
16 of 32
Classification
groups into which all living things are places according to their characteristics. The main groups are called kingdoms (there are five of these). The smallest subdivision is a species (there are millions of these).

Poikilotherms
Temperature varies with surroundings

Viviparous
give birth to live young

Species
a class of related, living organisms which are able to breed and produce fertile offspring.

Interbreed

30 of 32
Hybridisation
closely related species breed to produce offspring that have characteristics of both – the hybrids are often infertile
31 of 32
Ring Species
neighbouring populations of species may have slightly different characteristics but can still interbreed as part of a chain but the two ends of the chain can’t interbreed.
