• domains are the highest taxonomic rank which divides into: archaea, eubacteria and eukarya

Question 2

Answer 2

• prokaryotae, which contain prokaryotic cells
• Protoctista are eukaryotic cells
• fungi, they are all eukaryotric cells, have non-cellulose cell walls, they are saprotrophs and reproduce using pores
• plantea, multicellular eukaryotic cells, they have cell walls made up of cellulose, posses large vacuole, have chloroplast and are autotrophs
• animalia are multicellular eukaryotic organisms, no cell wall and are heterotrophs

Question 3

how is the variety of life is threatened by human activities and factors

Answer 3

• the population of human is increasing, therefore there is conflict between human needs and conservation biodiversity
• habitat destruction, overexploitation ((they
  are being used up faster than they can be replaced), hunting, agriculture (harvesting monoculture which would reduce biodiversity) and climate change

Question 4

what does biodiversity mean

Answer 4

• the number of different species and genetic diversity within specie

Question 5

what does endemic mean

Answer 5

• that this species are native to a particular

Question 6

how biodiversity can be measured within a habitat using species richness, and within a species using genetic diversity

Answer 6

• random sampling is used estimate the distribution and abundance of species
