Question 17

xHy

Answer 17

healthy male

Question 18

antigens

Answer 18

protiens that carry an immune response

Question 19

agglutination

Answer 19

clumping triggers the immune response

Question 20

blood type A

Answer 20

antigen A, anibody B, can give blood to A and AB, can get blood from A and O, genotypes AA AO

Question 21

blood type B

Answer 21

antigen B, antibody A, can give to B and AB, can get from B and O, genotypes BB BO

Question 22

blood type AB (rarest)

Answer 22

antigen A and B
no antibody
can give blood to AB
can get blood from everyone
genotypes AB

Question 23

type O

Answer 23

no antigens
antibody A and B
can give to everyone
can get from O
genotypes OO

Question 24

evolution

Answer 24

a change in living organisms over time

Question 25

changes in alleles=

Answer 25

enviromental pressure

Question 26

mutation

Answer 26

alleles change because of random base pair changes that doesn’t cause apoptosis (lactose and tolerant)

Question 27

genetic drift

Answer 27

alleles frequency change because there is suddenly a small population from which to draw alleles (a low population regenerates over time)

Question 28

gene flow

Answer 28

alleles change because new populations mingle (dominant genes take over)

Question 29

natural selection (survival of the fittest)

Answer 29

alleles change because they become better suited to the enviroment (white moths turn into black moths)
