Observation | |||
lab and field | |||
controls and variables | |||
contamination << creates a new variable that messes up the experiment | |||
Constant | |||
temp 20 | |||
temp 20 | |||
temp 20 | |||
temp 10 < = not constant | |||
species= a type of organism | |||
replication = a species increasing its population | |||
> replicate = copy, make more of | |||
>> cells divided and replicate | |||
>> DNA replicates | |||
>> | |||
vocab/ skills: | |||
graphing | |||
data to tables | |||
lab rules / procedures (goggles, apron, gloves etc.) | |||
contamination | |||
> proper handling of materials/ slides w/ specimins (things to study) | |||
Cell theory | |||
> prokaryotic cells | |||
> eukaryotic cells | |||
organelles: | |||
> single cell | |||
> whole organism | |||
cell membrame model | |||
> surface area | |||
> volume | |||
> surface to volume ratio | |||
cell division | |||
life processes | |||
> how cells move materials from outside to the center of the cell | |||
>> the more surface the more materials | |||
>> the higher the surface to volume ration, the more energy the cell can get for its needs | |||
> 20 um model, 10 um model, 4 um model, 2 um model | |||
mitosis | |||
> rapid mitosis | |||
zygote | |||
structure of DNA | |||
> cell growth & division | |||
> gamete formation ("game-T") | |||
> cell specialization | |||
> traits | |||
>> inheritance of traits | |||
>> Mendelian laws of heredity | |||
history of DNA structural model | |||
> Wilkins/Franklin x-rays that showed shape of DNA > "helical" (spiral) | |||
>> helix (double spiral structure of DNA) | |||
> structure = the form, the way the DNA is built | |||
fossils | |||
fossil record | |||
organic material | |||
Ascidian > marine (sea) organisims | |||
>> chordates | |||
>> other sea creatures = annelias, cnidarians, sponges | |||
> | |||
Chordates = origin/ ancestors of fish, birds, mammals | |||
>> so they have common traits such as similar embryos | |||
>> embyro = baby form (as in the womb or an egg) | |||
genetic variation | |||
> change in genes/ DNA | |||
> reproductive strategies | |||
> environmental pressures | |||
>> survival of populations | |||
> natural selection | |||
> population dynamics (change in populations and what causes them) | |||
atmosphere | |||
photosynthesis | |||
> oxygen | |||
> CO2 | |||
ecosystems | |||
> carrying capacity | |||
> equilibrium (equal, or stable, non-changing populations) | |||
