ANSWERS(RATED A+)
Scientific method - ANSWER1. pose a problem or question
2. formulate a hypothesis or educated guess
3. conduct experiments or tests that will provide a basis to solve the problem or
answer the question
4. observe test results
5. draw conclusions
scientific fact - ANSWERobjective and verifiable conclusion
scientific theory - ANSWERgreater body of accepted knowledge, principles, or
relationships that might explain a scientific fact
scientific law - ANSWERexplanation of events that always lead to the same outcome
model - ANSWERrepresentation of an idea that can be used to explain events or
applied to new situations to predict outcomes or determine results
anton von leuwenhoek 1723 - ANSWERused magnifying glass. first to observe
single celled organizms
minerals (geology) - ANSWERnaturally occuring, inorganiz solids with a definite
chemical composition and an orderly internal crystal structure
polymorph (geology) - ANSWERtwo minerals with the same chemical composition
but different crystal structure
rocks (geology) - ANSWERaggregates of two or more minerals and may also contain
mineraloids
-classified based on formation and minerals contained
-sedimentary
-volcanic (igneous)
-metamorphic
gregor johan mendel 1884 - ANSWERfather of genetics
-observed occurence of inhereted traits in pea plants
barbara mclintock - ANSWERcreated first genetic map of maize and was abke to
demonstrate basic genetic principles such as how recombination is an exchange of
chromosomal information
, james watson and francis crick - ANSWERco-discoverers of DNA (deoxyribonucleic
acid) which has a double helix shape
metric system - ANSWERkilo=1,000
hecto=100
deka=10
-base unit (gram, meter, liter)
deci=1/10
centi=1/100
milli=1/1000
mean - ANSWERsum of list of numbers divided by number of numbers
median - ANSWERmiddle number in list of numbers sorted from least to greatest. if
list is even numbers, median is smaller of two in middle
standard deviation - ANSWERthis measures the variability of the data set and
determines the amount of confidence one can have in the conclusions
mode - ANSWERvalue that occurs most frequently in the data set
range - ANSWERdifference between highest and lowest numbers (used to
determine how spread out data is)
regression analysis - ANSWERmethod of analyzing sets of data and sets of
variables that involves studying how the typical value of the dependent variable
changes when any one of the independent variables is varied and the other
independent variables remain fixed
mineraloids - ANSWERminerals lacking a crystalline structure
sedimentary rock - ANSWERformed through lithification (compaction, the expulsion
of liquids from pores, and cementation of pre-existing rock)
-pressure and temperature drive this process
-detrital, biogenic, and chemical
igneous rock - ANSWERformed from magma
-intrusive, plutonic, hypabyssal, extrusice or volcanic
-magna that solidifies at depth is intrusive, cools slowly and has course grain
-magma that solidifies at/near the surface is extrusive, cools quickly and has fine
grain
-hypabyssal rock is formed at medium depths
metamorphic rock - ANSWER-that which has been changed with heat and high
pressure
-deformation, compaction, destruction of the characteristics of the original rock,
bending, folding, formation of new minerals through chemical reactions, changes in
size/shape of mineral grain
-foliated-compressed along one axis
