module 4 classification

Question 1

classification

Answer 1

living organisms sorted into groups. these have similar features

Question 2

ACRONYM

Answer 2

Dead King Philips Came Ovdomain kingdom, phlym, class, order, family genus, species.

Question 3

why are organisms classifed

Answer 3

identify species.
predict characteristics
find evolutionary links.

Question 4

how are organisms linked?

Answer 4

seperated to 3 domains. archea, bacteria, eurkarya.
end with species,

Question 5

species

Answer 5

group of organisms able to produce fertile offspring.

Question 6

naming organisms

Answer 6

names in different languages, lead to no information, so is now names like first words=genus, second word=specie. UNDERLINE!

Question 7

prokaryote

Answer 7

unicellular
no nucleus
no membrane bound organelles
no feeding mechansisms-only produced by photosynthsis.

Question 8

protoscia

Answer 8

mainly unicellular
nucleus and other membrane bound organelles
some have chloroplasts
some as sessile
some move by cillia, flagella.
photosynthsis.

Question 9

fungi

Answer 9

multicelluar/unicellular
nucleus
chitin cell wall
no chloroplast
most have body
glycogen is must

Question 10

plante

Answer 10

multicellular
nucleus and membrane bound organelles
chloroplasts
cell wall=celluose
gamate, move by cillia
photosynthsis
starch.

Question 11

animal

Answer 11

multicellular
nucleus and other membranes
no chloroplasts
cillia and flagella
nutrients
glycogen stored.

Question 12

phlogenetic trees

Answer 12

diagrams representing evlontiary relationships.
are branched diagrams, shows species-evolution.

Question 13

advantages of phylogenetic classification

Answer 13

continous trees, whereas classification needs discrete.
classification can be misleading, different group with rankse

Question 14

evidence of evolution

Answer 14

darwin realised organisms suited to environment survival.
theory of organism evolving.

Question 15

developing evolution

Answer 15

many people believed bible, where Darwin carried experiments in islands, bird was similar in many ways, claws beaks were different shaped.

Question 16

evidence of evolution

Answer 16

Palaeontology
comparative anatomy/chemistry

Question 17

Palaeontology

Answer 17

fossils formed over long times, so sediment is desposisted, making sequence of youngest to oldest. NOT COMPLETE

Question 18

comparative anatomy

Answer 18

homologus structure, structure different, but same things usage, like pentadactyl limb. EVIDENCE of divergent evolution

Question 19

divergent evolution

Answer 19

different species have evolved, with different adaptive features.

Question 20

comparative biochemistry

Answer 20

study in similar and difference in proteins and other molecules.
slight changes=help links for evolution.
neutral evolution=change dosent affect function.
molecule sequences are compared, and no of differences are plotted against rate, so can estimate with share ancestor.

Question 21

interspecific variation

Answer 21

number of different species

Question 22

causes of variation

Answer 22

genetically
environmentally

Question 23

genetically changes?

Answer 23

allele, genes having different alleles, so different effects.
mutations leading to changes in DNA sequences

Question 24

adapations

Answer 24

anatominal, behavioral, physological

Question 25

anatominal

Answer 25

body covering, camoflauge, teeth, mimicary

Question 26

behavioral

Answer 26

act dead.
courtship
seasonal

Question 27

physological

Answer 27

production of poison/antibotics.

Question 28

analogus structures

Answer 28

adapted to perform same structure but different alleles

Question 29

covelgent evolution

Answer 29

unrelated species begin to have similar traits, evolve to adapt to similar environments.

Question 30

natural selection

Answer 30

1)organisms show variation due to genetic (alleles, mutation).
2)organisms adapted to selection pressure, so more survival, more reproduction, and survival of the fittest.
3)pass to offspring
4)reperated, more gene pool

Question 31

s
