increases blood pressure.
Arteries Away - Veins towards. Systolic- Squeezing Diastolic- Resting Contractions of the Ventricle are responsible for Blood Pressure 120/80 sphygmomanometer Slows the flow – increases blood pressure.
2
ATHERSCLEROSIS Blood Pressure
Viscosity (thickness)- increases resistance- slows the flow- increases blood pressure. Plaque- blocks arteries ( decreases diameter) slows the flow - increases blood pressure. Too mush salt, lack of exercise – fatty diet- increases blood pressure Blood Vessels Constrict – Increases blood pressure. ATHERSCLEROSIS Loss of blood volume- decreases blood pressure
3
Effects of Exercise 1. Increases Heart Rate
2. Blood vessels dilate to increase blood flow. - carry more oxygen 3. As you exercise blood is directed to your muscles.

Fast Slower Vaccine MEMORY CELLS
Innate (VS) Acquired Fast Slower Vaccine LONG TERM SHORT TERM MEMORY CELLS
5
Active Passive 1st and 2nd 3rd Defense
6
Produced by your own body - ACTIVE Specific Target an Antigen
Antigens- Antibodies Produced by your own body - ACTIVE Specific Target an Antigen
7
Natural Selection in Bacteria
SUPER BUGS Antibiotic Resistance
8
Antibiotics Only work on bacterial infections – NOT VIRUSES
Improved medicine and sanitation has decreased the number of transmittable diseases.
10
Ovum & Hormones Fertilization Implantation
11
Zygote- Fertilized Egg. Made of one cell
You need to know the process of human development from zygote to birth. Zygote- Fertilized Egg. Made of one cell Blastocyst-hollow ball of dividing cells, that implants in the Uterus
12
Amniotic Sac - Protection Placenta Placenta- nourishes embryo Yolk Sac

17
Disproves spontaneous generation
Cell Theory All living things are composed of cells. Unicellular & Multicellular Cells are the smallest unit of life. All cells come from other cells. Disproves spontaneous generation
18

EUBACTERIA- E. Coli.
19
Endosymbyosis P E Simple to Complex
20
Plant (vs) Animal Cell Plant Animal Cell Wall Centrioles Chloroplast
Larger Vacuole
21
Chloroplast 11 “Photosynthesis” production of glucose and oxygen.
*Larger in Plants 11 “Photosynthesis” production of glucose and oxygen.
23
Semi-permeable – Selectively permeable
24
Quick Energy Stored Energy Cell Membrane Folded DNA & RNA
25
Lipid-soluble (non-polar) substances pass through the membrane.
Fluid Mosaic Model Polar Non-Polar Lipid-soluble (non-polar) substances pass through the membrane.
26
HIGH to LOW HIGH to LOW No Energy Energy
27
Diffusion - movement of molecules from an area of higher concentration to an area of lower concentration.
28
H2 Osmosis Diffusion of Water

Cell Cycle
31
Mitosis Cell division Produces two identical diploid daughter cells
Occurs in body cells to grow and repair
32
2 1 2 4 Diploid (2n) Haploid (n) Diversity
33
2 1 Mitosis 1 2 4 Meiosis GAMETES
34
P.M.A.T Both mitosis & meiosis
35
Cells growing out of control !
CANCER Any of various malignant neoplasms characterized by the proliferation of anaplastic cells that tend to invade surrounding tissue and metastasize to new body sites. Cells growing out of control !
36
Separate Law of Segregation
States that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. Separate
37
Law of Independent Assortment
-states that allele pairs separate independently during the formation of gametes. Leads To Diversity Variation
38
Only way recessive show
Genetic Terms Identical factors- -TT,tt Different Factors – Tt (hybrid) Homozygous Heterozygous Only way recessive show have to have two of them
39
Heterozygous & Heterozygous
40
Incomplete dominance -not completely
This results in a combined phenotype. Mixture of traits….
41
Both traits are visible….
Codominance - is a situation in which both alleles are equally strong and both alleles are visible in the hybrid genotype. Both traits are visible….
42
Codominance: both alleles are expressed: blood types
Universal Recipient Universal Donor
43
Multiple alleles: More than two alleles possible: blood types
Universal Recipient Universal Donor
44
Dihybrid Cross Must Know 9:3:3:1
45
Pedigree Chart
46
Male Hemophilia Female
47
DNA / RNA Carry genetic information Made of a chain of nucleotides
Nucleotides contain a sugar, phosphate, and a nitrogen base
48
DNA / RNA RNA Single stranded Four base pairs: AUCG Sugar is Ribose
Double stranded “Double Helix” Four base pairs: ATGC Sugar is Deoxyribose Found in nucleus RNA Single stranded Four base pairs: AUCG Sugar is Ribose
49
Replication Making of an identical strand of DNA “semi” conservative
50
DNA RNA protein trait
Central Dogma DNA RNA protein trait
51
Transcription DNAmRNA Occurs in nucleus
Complementary mRNA strand is produced from a segment of DNA
52
Translation Connects amino acids in the correct order to make a protein Occurs in the cytoplasm within the ribosomes A- amino acid B- tRNA C- anticodon D- codon E- mRNA F- Ribosome G-polypeptide
53
Codon Sequence of three mRNA nucleotides that code for an amino acid
54
Mutations Change in DNA code May cause a change in protein produced
NOT always harmful Sickle Cell Mutation
57
Replication Transcription Codon –composed of 3 Translation
58
A-U 20 amino acids DNA sequence: TAC GGA CAT AAC ACC TGC ATC
mRNA sequence: AUG CCU GUA UUG UGG ACG UAG
59
Macromolecules Lipid: Contain Carbon, Hydrogen and Oxygen (CHO)
Carbohydrate: Contain Carbon, Hydrogen, and Oxygen (CHO)
60

61
Quick Energy Stored Energy Cell Membrane Folded DNA & RNA
62
Lower Activation Energy
Enzymes specific for reactions speed up reactions (Catalyst) are made of PROTEIN Lock and Key Lower Activation Energy Activation Energy
63
