metamorphosis
cell membrane
the semipermeable membrane enclosing the cytoplasm of a cell.
meiosis
process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell
natural selection
natural process resulting in the evolution of organisms best adapted to the environment
Steroids
Composed of 4 carbon rings fused together with functional groups attached to the rings. Signals molecules and is a membrane component.
Chromosome
is a single large macromolecule of DNA, and constitutes a physically organized form of DNA in a cell. It is a very long, continuous piece of DNA (a single DNA molecule), which contains many genes, regulatory elements and other intervening nucleotide sequences. A broader definition of "chromosome" also includes the DNA-bound proteins which serve to package and manage the DNA.
Type I Diabetes
Insulin dependent
-Pancreas does not produce insulin, no way to maintain blood sugar level
Ignicoccus
-grows optimally at 90 degrees Celsius -metabolism is H2/elemental S based -hyperthermophilic -has an outer membrane, present at some distance from the cytoplasm of the cell wall -host to small, parasitic prokaryote (like Nanoarchaeum with a genomic size of .49 mbp)
Organisms make many proteins with highly specialized properties. These molecules illustrate the amazing range of functions that proteins can perform. The antifreeze proteins in Arctic and Antarctic fishes protect their blood against freezing
Special-purpose protein
alkaptonuria
rare genetic disease that made the patient's pee turn black when exposed to air
sporophyte
in organisms that have alternation of generations, the multicellular diploid form that results from teh union of gamets. The sporophyte produces haploid spores by meiosis that develop into gametophytes
Population
A localized group of individuals of the same species that can interbreed, producing fertile offspring.

an insect in the nonfeeding, usually immobile, transformation stage between the larva and the imago.
explain modeling
used to gain insight into complex phenomena such as the effects of global warming on ecosystems.

C) Deep purple
Oxygen debt
The amount of oxygen needed to reconvert lactic acid to pyruvate following strenuous exercise of muscle tissue.

an allele that does not express its protein
kinesis
a simple change in activity or turning rate in response to a stimulus
ovary - fruit
simple - one pistilcompound - aggregate (pistils from same flower) multiple (pistils from different flower)fleshydry
Cell Theory
-Cells are the basic structural and physiological units of all living organisms. -Cells are both distinct entities and building blocks of more complex organisms

particulate hyphothesis (genes)
idea that parents pass down heritable traits
Independent variable
this is the only factor that effects the outcome of the experiment
What may regulate movement of cations?
Gram positive cell walls
photosystem I
consists of a pair of chlorophyll a molecules with an absorption peak at 700 nm and is referred to as P700
cyclin
a protein that gets its name from its cyclically fluctuating concentration in the cell
What is consumed/produced in Glycolysis and where does the reaction enter the point of no return? 
Consumed: Glucose, NAD+, ADP, H2O(?)
Produced: 2 net ATP, 2 net NADH, and 2 pyruvates
 
The glycolysis pathway can be shut off at the step where the second phosphate group is added to make a symmetrical molecule. Phosphofructokinase can be inhibited by ATP at a regulatory site.
