Isolation
Species separated by a barrier.
1 of 48
Genetic Variation

2 of 48
Natural Selection
Where the alleles that help an organism to survive are selected in each population.
3 of 48
Speciation
The populations become so different that they cannot successfully interbreed.
4 of 48
Extinction
The permanent loss of all members of a species.
5 of 48
Species
Organisms with similar characteristics that can successfully interbreed to produce fertile offspring.
6 of 48
Stem Cell
An unspecialised cell.
7 of 48
Phenotype

16 of 48
Oxygen Debt
The extra oxygen that must be taken into the body, after exercise has stopped, to complete the aerobic respiration of Lactic Acid.
17 of 48
Anaerobic Respiration
Happens without oxygen, when there's not enough of it for aerobic respiration.
18 of 48
Glycogen
The substance glucose is stored as in the muscles.
