Law Correct Answ_An explanation of events that always leads to the same outcome.
Model Correct Answ_Used to explain something on a smaller scale or in simpler terms.
Scientific Method Correct Answ_Identify a problem
Formulate a hypothesis
Conduct experiments
Observe results
Draw conclusions
Peer review
Random errors in data Correct Answ_Sometimes called noise, wildly different from the rest
of the data. Does not affect average
,Systematic errors in data Correct Answ_Shows up consistently across a data set, may be the
result of a flaw in experimental design. Affects average, also known as bias.
Mean Correct Answ_Average
Median Correct Answ_Middle number
Mode Correct Answ_Value that appears most frequently
Range Correct Answ_Difference between highest and lowest numbers
Standard Deviation Correct Answ_How far from the mean is from a single data likely to be,
measures dispersion of data set
Ampere (A) Correct Answ_SI unit used to measure electric current
Kelvin (K) Correct Answ_SI unit used to measure thermodynamic temperature
,Candela (cd) Correct Answ_SI unit used to measure luminous intensity
National Science Education Standards Correct Answ_Understand scientific concepts
Appreciate "how we know" what we know in science
Understand the nature of science
Develop the skills necessary to become independent inquirers about the natural world
Develop the skills necessary to use the skills, abilities, and attitudes associated with science
Regression analysis Correct Answ_Method of analyzing sets of data and sets of variables
that involve studying how the typical value of the dependent variable changes when one
independent variable changes and the other remains the same.
Protosomic phyla Correct Answ_Mouths are formed from the blastospore. Ex: Mollusca,
Annelida, Arthropods
Animal phyla that lack a coelom or have a psedocoelom Correct Answ_Porifera, Cnidaria,
Platyhelminthes, Nematoda
# of invertebrates in animal kingdom Correct Answ_98% of animal species, 30 phyla
, Phylum Chordata Correct Answ_Vertebrates, two cavities - thoracic holds heart and lungs,
abdominal holds digestive organs. All have endoskeletons
Deuterostomic phyla Correct Answ_Anuses are formed from blastopores, Echinodermata
and Chordata
Epithelial tissue Correct Answ_Found on body surfaces and lining body cavities, ex: skin
and stomach lining. Functions are protections, secretion of chemicals, absorption of chemicals,
response to external stimuli. Contain no blood vessels so must receive nourishment from
underlying tissue
Connective tissue Correct Answ_Used to bind, support, protect, store fat, and fill space. Can
be loose or fibrous, ex: cartilage, bone, tendons, ligaments, blood, and protective layers.
3 types of muscle tissues Correct Answ_Cardiac, smooth and skeletal (striated)
11 Organ systems of the body Correct Answ_Skeletal
Muscular
