|
Energies not powered by the sun
|
Nuclear, Tidal, and Geothermal
|
|
|
Basic Equation
|
c6h12o6+o2=6co2+6h2o
|
|
|
Photosynthesis takes place where?
|
Chloroplasts
|
|
|
Parts of Leaf and what they do
|
Veins- water through leaf
Top of Leaf-densly packed cells filled w/ chloroplasts to do photosynthesis Inside-somata that allow O2 ad CO2 in |
|
|
2 parts of photosynthesis and what they do
|
The Light Reactions- split hydrogens off oxygen using light energy. use NADPH to help power Kelvin Cycle
Dark Reactions- take CO2 and link them and add in Hydrogen and sugars come out. |
|
|
Gene Therapy
|
Taking a good gene from someone and putting it into someone with a bad gene.
|
|
|
Why pea pods are ideal-4 reasons
|
1. Easy to Cultivate
2. Self Pollinate if left alone 3. Contain different characteristics 4. Can cross individual plants by transferring pollen |
|
|
Monohybrid cross
|
cross involving 2 parents that are true breeding for different traits in one character
|
|
|
alleles
|
alternative versions of the same gene
|
|
|
homozygote
heterozygote |
individual that has 2 identical alleles at a given gene
individual that has 2 different alleles at a given gene |
|
|
phenotype
genotype |
physical appearance of an organism due to a trait or a set of traits
the underlying genetic composition |
|
|
Mendel's First Law + what?
|
Law of Segregation- when gametes are produced , 2 alleles of a given gene will separate so that each gamete only recieves one member of alleles
|
|
|
Ways for law of segregation
|
Punnet Square
Test Cross Probability Analysis |
|
|
Test Cross
|
Finding unknown individual by crossing it with a homozygous individual
|
|
|
Probability
|
The chance that an event will occur
Definitely - 1 No - 0 |
|
|
Rule of Multiplication
|
if there are 2+ chance events and they each must occur, the total can be found by multiplying the separate probabilities
|
|
|
Rule of Addition
|
if there are 2 or more mutually exclusive events and 1 or the other can occur, the total can be found by adding the separate probabilities
|
|
|
Dihybrid Cross
|
cross between 2 true breeding that differ in the traits of the 2 characters
|
|
|
Mendels 2nd law and what
|
The law of Independent Assortment-
alleles of different genes will assort independently of one another during gamete formation |
|
|
Wild Type
|
Allele that is most common in nature that gives rise to an expected phenotype
|
|
|
polymorphic locus
|
when a wild type allele is present less than 95-99% of the time
|
|
|
monomorphic locus
|
when a wild type allele is present more than 95-99% of the time
|
|
|
Other genes besides complete dominance and what
|
incomplete dominance-mix of alleles (flowers)
codominance-both alleles are shown (blood types) overdominance (hybrid vigor)- heterozygote is better off |
|
|
stages of meiosis
|
interphase- cell with nucleus (state in which cell always lives)
prophase-nucleus dissappears and chromosomes condense metaphase-chromosomes line in middle anaphase-split and migrate to opposite ends of cells telephase-(citokinesis) condense back to form new nucleus |
|
|
chromotid
chromosome |
1 strand of DNA
sister (2) chromotids. we have 46 |
