3.1

Question 1

morphology

Answer 1

physical apearance

Question 2

analogus features

Answer 2

features that look similar or have the same function

Question 3

homologus structures

Answer 3

structures that shows common ancestry

Question 4

dna sequences

Answer 4

the base sequence of all or part of the genome of an organism is worked out

Question 5

dna profiling

Answer 5

leads to the dna profiling which looks at the non coding areas of dna to identify paterns

Question 6

bioinformatics

Answer 6

development of software and computing tools needed to organise and analyse raw biological data

Question 7

gel electrophoresis

Answer 7

dna is cut into fragments by restrictive enzymes
pcr to amplify
added to gel
pd is applied
DNA is negatively charged so moves to positive
fragments are separated
light move further
more close the bands the closer the relation

Question 8

3 domains

Answer 8

archea
bacteria
eukaryota

Question 9

binomial system

Answer 9

italics
capital then lower
genus then species

Question 10

morphogical species concept

Answer 10

based on apearance

Question 11

reproductive,biological species concept

Answer 11

species can interbreed to from firtile offspring and genes can flow

Question 12

ecological species model

Answer 12

based on ecological neiche

Question 13

mating recognition species model

Answer 13

based on mating behavior

Question 14

genetic species model

Answer 14

based on dna

Question 15

evolutionary species model

Answer 15

based on evolutionary relationships

Question 16

limitations of species model

Answer 16

finding the evidence
plants frequently interbreed
ne sexual reproduction
fossils dont have dna

Question 17

how are finding validated

Answer 17

published in a journal
peer reviewed
presented at a conference
experiment repeated

Question 18

3 domain or 5 kindom

Answer 18

molecular phylogeny e.g protein biochemistry
similarities between archea and bacteria
e.g membrane structure

Question 19

why does gel elctrohersis work

Answer 19

each person has individual dna

Question 20

what can be used to classify a new species

Answer 20

compare physical characteristics
observe behavior/neiches
use dna sequencing
use gel electrophoresis
see if breeds for fertile offspring
bioinformatics
ecological neiches
