    Its basically when you ensure that the experiment is conducted under sterile conditions so for the garlic and mint anti microbial properties it was basically to ensure that petri dishes containing the micro organisms were not completely opened to prevent contamination.

    Biodiversity
    · Variety of living organisms in an area

    Species diversity
    · Number of different species (in an area)
    · Abundance of each species (in an area)

    Genetic diversity
    · Variation of alleles within a species

    Species richness
    · the number of species ;
    · in {an area /one location /habitat} ;

    Endemic
    · idea that the ( species / eq ) is restricted in its distribution / species only found in one specific { location / area / eq }

    Habitat
    · The area in which an organism lives
    (i got these definitions from the revision notes which were posted on the 4th page of this thread)

    I think there will be a lot of topic 3 emphasis this time, so this may well make grade boundaries a bit lower this time. Unit 1 grade boundaries in January were absolutely ridiculous...
