18
Q

taxonomy

A

study and praise of naming and classifying species and groups of species within hierarchal classification system

19
Q

hierarchal classification

A

arrangement of organisms into groups of different ranks. Lowest is species, similar species are grouped together into the next rank genus. Highest rank is domain where many species are grouped together

20
Q

3 different domains

A

bacteria archaea eukarya

21
Q

which domains are prokaryotes

A

bacteria and archaea

22
Q

kingdoms of eukarya

A

protoctists fungi plantae animilia

23
Q

what sort of nutrition to animals and fungi use

A

heterotrophic

24
Q

heterotrophic nutrition

A

use organic molecules made by other organisms as a source of energy

25
Q

what type of nutrition do plants have

A

autotrophic nutrition

26
Q

how do you know if a protoctist is animal like

A

no cell walls

27
Q

what is an animal like protoctist called

A

protozoa

28
Q

do fungi ever have cilia

A

no

29
Q

plants vs animals specialised cells

A

plants have much less specialised cells

30
Q

eukaryotes vs prokaryotes

A

80s vs 70s ribosome in cytoplasm
membrane vs non membrane bound organelles
cell division
linear vs circular DNA

31
Q

how do prokaryotes divide

A

binary fission

32
Q

what do bacteria and archaeans have in common

A

no nucleus
plasmids present
no membrane bound organelles
70s ribosomes
cell walls
divide by binary fission

33
Q

bacteria vs archaeans differences

A

circular DNA vs Linear DNA associated with histones

peptidoglycan cell wall vs none

34
Q

mass extinction

A

when rates of extinction are extremely high

35
Q

what is mass extinction caused by

A

major/sudden shift in environment like ace age or asteroid

36
Q

what causes extinction 5

A

climate change
competition
introduction of species
human hunting
degradation and habitat loss

37
Q

why maintain biodiversity 5

A

moral ethical reasons
ecological reasons
aesthetic reasons
agricultural reasons
economical reasons

38
Q

how does fossil fuels effect animals

A

increased co2 levels in air dissolves into large bodies of water like the ocean
co2 forms carbonic acid which dissociates in H+ ions which lowers the pH of the water weakening shells made of calcium carbonate

39
Q

3 levels of biodiversity

A

number and range of ecosystems and habitats

number of different species in an ecosystem and relative abundance

genetic variation (diversity of alleles in genomes) within each species

40
Q

endemic species

A

found only in a certain area and nowhere else

41
Q

ecosystem

A

relatively self contained interacting community of organisms and the environment they live in and interact with. All the biotic and abiotic factors

42
Q

community

A

all the living organisms of all species of organisms in a particular ecosystem at a particular time
