2- Adaptive radiation a population splits and
different traits are adaptive. - Geographic isolation part of a population is
separated. - Genetic diversity by mutation or in gene pool
- Natural selection
- Variation in populations
- Overpopulation or predators
- Competition for survival/mates
- Survival/reproduction of best adapted / fittest.
- Biochemical analysis (DNA, amino acids, proteins)
- Fossil record
- Anatomy (if similar bone arrangement homologous
- Development / embryology
- More in common more related
A

C
- Separates DNA by size (smallest goes farthest)
- Identifies paternity and criminals
- Prokaryotic cells (no nucleus no membrane-bound
organelles) unicellular - Important for
- decomposers,
- for Nitrogen cycle,
- for gene research (recombinant DNA with plasmids)
- First cells to evolve

- Flowers reproductive organ of angiosperm plants
- Male part stamen/pollen
- Female part carpel or pistil (produce egg)
- Pollination transfer of pollen
- Seed plant embryo stored food (endosperm).
Surrounded by fruit (forms ovary of plant.)
- Not living because they cannot reproduce outside
a living organism (have no cells) - Two reproductive cycles
- Lytic fast, destroys cell
- Lysogenic slower, viral genetic material hides
in cell

4- Opposites of each other
- Photosynthesis
- Converts sunlight into chemical energy
- CO2 H20 light ? glucose O2
- Respiration
- Converts sugars into cell energy (ATP)
- C6H12O6 O2 ? H2O CO2 ATP
- Used by ALL ORGANISMS!!
Made of Examples C
Monosaccharide Sugar, starch P Amino
acids Meat, enzymes L Fatty acids
and fats, oil, was glycerol or
phosphate phosopholipid NA Nucleotides
DNA and RNA
Chloroplasts site of photosynthesis Mitochondr
ia site of cellular respiration Ribosome
site of protein synthesis Site means
location!

Plant Cells have cell walls, chloroplasts,
large vacuoles Animal Cells have Centrioles
(used for cell division) BOTH ARE EUKARYOTIC!
(have membrane bound organelles and a nucleus)
- Lock and Key
- Acts as a catalyst (speed up reactions)
- Lowers activation energy
- Works best at Optimum conditions! (this is
different for each enzyme)
Cells lose water in saltier than usual
environments because of osmosis!!
O
N
M
- Selectively permeable (regulates materials coming
in/out of the cell) - Gives cytoplasm a boundary / shape
- HOMEOSTASIS (home stays as it!!)
mRNA makes copy of DNA/gene and takes to
ribosome rRNA makes up ribosome along with
proteins tRNA brings an amino acid to the
ribosome, anticodon pairs with mRNA codon

Found on a chromosome Section of DNA Used to
make a protein Controls traits!
S

T
- Mitosis
- Makes identical copy of cell
- Produces 2 daughter cells
- Used by somatic body cells
- Meiosis
- Reduces chromosome number by half
- Produces 4 daughter cells
- Makes haploid gametes
Homozygous Dominant (AA) Heterozygous
(Aa) Homozygous recessive (aa)
Recessive phenotype
- Sex cells
- Haploid (contains only one copy of each
chromosome/half of diploid) - Fuse together in fertilization
Dominant Phenotype
X
W
V
- DNA from two different species!
- Plasmid Human gene
- cleave
- splice together
- Geneplasmid
- Recombinant DNA
- Dominant one allele dominant
- Recessive allele hidden by dominant
- Codominance both alleles equal, both show up!
- Incomplete Dominance Neither allele dominant,
blending together - Sex-linked on X chromosome, no male carriers
- Picture of chromosomes (should have a total of 46
(23 pairs) - Shows chromosomal abnormalities (Ex. Downs
Syndrome Trisomy 21) - Usually follows an amniocentesis

8- Carbon Cycle
- - Respiration releases carbon as CO2 (carbon
dioxide) - Photosynthesis removes carbon and makes sugar
(C6H12O6) - Burning Fossil fuels releases CO2
- Nitrogen Cycle
- Nitrogen-fixing bacteria remove N2 from air and
make nitrates - - Nitrogen in the air -gt bacteria -gt plants -gt
animals Fertilizers add excess nitrogen
- Two species living together permanently
- Mutualism ( ) both benefit
- Commensalism ( 0) one isnt helped or harmed
- Parasitism ( -) One is harmed
Biosphere (all of life on earth) Biomes (ex.
Desert, grassland) Community (only
biotic/living) Population (members of one
species) Niche (total way of life for organism,
food)

- Exposure to antigen (foreign invader)
- T cells sound alarm and destroy antigens
- B cells make protein antibodies which tag
antigens - B cells remember to make antibodies forever,
resulting in active immunity (vs. passive where
antibodies are given, not made)
- Overpopulation cause of all environmental
problems - Global warming too much CO2 in atmosphere
increases average global temperature -gtflooding,
climate change - Ozone depletion CFCs destroy ozone layer -gt
increase UV radiation exposure -gt increases
cancer and crop damage
- Pesticides and contaminants move up the food
chain - Chemical contaminants are stored
(bioaccumulation) and magnified in organisms
higher up the food chain because predators
accumulate pesticides in the bodies of their
prey.

- Instinctive behaviors improve survival rates.
- Protective behaviors (spray, teeth bared) turn
predators away and defends resources - Parental behaviors (advanced in birds and
mammals) increase survival of young. - Communication and courtship allow mate
recognition
- Require higher level nervous system change with
experience and practice. - Classical conditioning (unrelated stimulus and
reward/punishment - Operant conditioning (trial and error learning)
- Insight / reasoning
- Language
- Genetic and Inborn
- Automatic (reflex and instinct)
- Courtship
- Territoriality
- Aggression
- Dominance hierarchy
- Biological rhythms (migration, clocks)
- Some communication (need to sing in birds)

9- EOC Review Flashcards
- Match up fronts (numbered words) and backs
(definitions with letters) and staple, glue or
tape them together. You should have 36 total. - Draw a picture on each front.
- On a separate sheet of paper
- Write 6 sentences that connect two different
words/phrases. Underline the words/phrases. - Write 5 sentences that connect three different
words/phrases. - Write 4 sentences that connect four different
words/phrases. - Write 8 sentences that connect one word/phrase
with a STERNGRR word. - Example Viruses and bacteria can both
infectious agents, but (what more can be added
to make this useful?)
