25
bloody type O
antigen none, antibody A and B, can give blood to everyone, can get from only O, genotypes OO
26
rh factor
with Rh = dominant without Rh = recessive
27
frequency
a change in living organisms over time/a change in the frequency of allels in a population over generations
28
mutation
allels cahnge because of random base pair changes (babies become lac-tose tolerant over time)
29
genetic drift
allels frequency change because there is suddenly a small population from which to draw allels, (a low population regenerates stronger over time)
30
gene flow
allels change because new populations mingle (when dominant genes overtake other dominant genes)
31
natural selection
allels change because they become better suited to the enviroment (white moths turn into black moths)
32
gregor mendal
father of modern genetic, showed hoe traits are inherited, peaplants, monk teacher garderner, no funds for school
33
reginald C. Punnet
proffesor of genetic in the united kingdom, propabities of genetic outcome, 2 marine worms are named after him, degree in zoology
34
karl landsteiner
father of transfusion medicine, discovered 4 human blood types, landsteiners principla, born in Australia, won a nobel prize
35
Charles Darwin
wrote orgin of species, naturalist, biologist, explorer, believied in natural progressive theory
36
segmentation leads to
free movement and development of certain body parts
37
how many parts of the brain are there
6
38
frontal lobe
logic and thinking
39
motor cortex
specialized area for senses
40
parental lobe
movement, response to stimuli
41
occipital lobe
visual proccesing
42
cerebellum
muscle control, balance
43
temporal lobe
memory, speech, hearing
44
coelum
the main body cavity
45
endothermic
being able to regulate your body tempature
46
exothermic
body temp stays the same where ever
47
ectothermic
body temp changes on the enviroment
48
internal gestation
to carry babies on the inside
49
protien
use:build tissues/other molecules test:biruet test monomer:amino acids
50
lipid
use:membrane/energy storage test:droplet test monomer: fatty acids
51
sugar and starches
use:energy (ATP) test: sugar (benidict test) starch (iodine test) monomer: monosacchonde
52
nucleic acids
use:genetic information/storage test: nemotoxylin monomer: nucleotides
53
catabolic
breaks bigger molecules down
54
anabolic
makes larger molecules from smaller molecules
55
metabolism
a chemical reaction that occurs with food to turn it into energy within the digestive system
56
activation energy
the hump on the line after reactants and before products, it is important because the higher the hump, the slower the reaction
56
enzymes
special protiens that allow metabolic reactions to occur speeds them up 1. enzyme concentration 2. substrate concentration 3. competitive inhibitors 4. non-competitive inhibitors
57
endothermic
absorb heat
58
exothermic
release heat
59
atp
provide reusable energy between the second and third phosphate groups
60
protien enzyme
pepsin trypsin
61
lipid enzyme
lipase
62
sugar and startch enzyme
amylase pectinase
63
nucliec acids enzyme
nuclease
64
catalysts
protiens that help a reaction start
65
gamma bond
the bond between two phosphates
66
instestine purpose
enzymatic digestion and absorption of nutrients aborbstion of water and electrolights removal of solid waste from body
67
large intestion
5 feet long site of water absorbtion aka: the colon
68
small intestion
22 feet long duodenum lleum jejunum
69
villi
shaggy hair lactates increase surface area absorbs into blood vessels and lymphatic vessels
70
lacteal
a blood vessel that takes away fat from digestive areas
