MTTC Integrated Science Exam Questions
With Correct Answers
Independent ||Variable ||- ||CORRECT ||ANSWER✔✔-The ||experimental ||factor ||that ||is ||
manipulated; ||the ||variable ||whose ||effect ||is ||being ||studied. ||Placed ||on ||the ||x-axis ||(horizontal)
||on ||a ||graph.
Dependent ||Variable ||- ||CORRECT ||ANSWER✔✔-The ||variable ||that ||is ||measured ||in ||an ||
experiment. ||Placed ||on ||the ||y-axis ||(vertical) ||on ||a ||graph.

relative ||impact ||of ||an ||independent ||variable
Response ||to ||Lab ||Accident ||- ||CORRECT ||ANSWER✔✔-In ||most ||cases, ||911 ||should ||be ||called ||
immediately.
Response ||to ||Fire ||in ||a ||Beaker ||or ||Flask ||- ||CORRECT ||ANSWER✔✔-Do ||not ||use ||a ||fire ||
extinguisher. ||Just ||place ||a ||watch ||glass ||or ||wet ||towel ||over ||it ||to ||cut ||off ||Oxygen ||supply.
,Guidelines ||for ||Dissections ||- ||CORRECT ||ANSWER✔✔-Specimens ||should ||be ||rinsed ||before ||
using. ||Latex ||glover ||preferred. ||Avoid ||use ||of ||formaldehyde/dispose ||of ||correctly. ||Need ||to ||
provide ||alternative ||for ||students ||with ||moral ||objections ||to ||assingment.
Storing ||Lab ||Chemicals ||- ||CORRECT ||ANSWER✔✔-Store ||all ||in ||secured, ||dry ||area. ||Acids ||
locked ||in ||separate ||area.
Origin ||of ||Biological ||Sciences ||- ||CORRECT ||ANSWER✔✔-Traced ||back ||to ||ancient ||Greeks ||(i.e. ||
Aristotle)
Andrea ||Vesalius ||- ||CORRECT ||ANSWER✔✔-Dissected ||human ||bodies; ||created ||a ||book ||on ||
anatomy
Anton ||van ||Leeuwenhoek ||- ||CORRECT ||ANSWER✔✔-Father ||of ||Microscopy, ||first ||to ||see ||and ||
describe ||bacteria, ||yeast ||plants, ||and ||microscopic ||life ||found ||in ||water
Scanning ||Electron ||Microscope ||(SEM) ||- ||CORRECT ||ANSWER✔✔-Instead ||of ||a ||light, ||a ||beam ||
of ||electrons ||pass ||through ||specimen. ||Resolution ||about ||1,000 ||times ||greater ||than ||light ||
microscope. ||Will ||kill ||specimen ||though.
Robert ||Hooke ||- ||CORRECT ||ANSWER✔✔-Famous ||for ||Hook's ||law ||describing ||elasticity. ||But ||
called ||a ||"virtuoso", ||able ||to ||contribute ||findings ||to ||any ||major ||field ||in ||science
Carl ||Von ||Linnaeus ||- ||CORRECT ||ANSWER✔✔-Famous ||for ||binomial ||system ||of ||nomenclature.
||Each ||living ||organism ||has ||two ||names, ||a ||genus ||and ||species. ||Considered ||father ||of ||
modern ||ecology ||and ||taxonomy
Pasteur ||- ||CORRECT ||ANSWER✔✔-Discovered ||role ||of ||microorganisms ||in ||the ||cause ||of ||
disease, ||pasteurization, ||and ||rabies ||vaccine.
,Koch's ||Postulates ||- ||CORRECT ||ANSWER✔✔-Specific ||diseases ||caused ||by ||specific ||pathogens
Cell ||theory ||- ||CORRECT ||ANSWER✔✔-Cell ||is ||the ||common ||structural ||unit ||in ||plants ||and ||
animals. ||Proposed ||by ||Mattias ||Scheleiden ||and ||Schwann.
Watson ||and ||Crick ||- ||CORRECT ||ANSWER✔✔-Discovered ||the ||structure ||of ||DNA ||was ||a ||
double ||helix ||(in ||the ||1950s). ||Made ||it ||possible ||to ||understand ||how ||DNA ||replicated ||and ||
synthesized ||proteins
Commonalities ||Among ||all ||Sciences ||- ||CORRECT ||ANSWER✔✔-- ||Systems, ||order, ||and ||
organization
- ||Evidence, ||models, ||and ||explanation
- ||Constancy, ||change, ||and ||measurement
- ||Evolution ||and ||equilibrium
- ||Form ||and ||function
Empirical ||Evidence ||- ||CORRECT ||ANSWER✔✔-All ||evidence ||is ||empirical; ||all ||evidence ||must ||
be ||observed ||by ||the ||five ||sense.
Peer-reviewed ||Journals ||- ||CORRECT ||ANSWER✔✔-Most ||accepted ||source ||for ||information ||on
||scientific ||experiments ||and ||studies
Air ||Pollution ||- ||CORRECT ||ANSWER✔✔-Chemicals ||in ||the ||air; ||include ||carbon ||monoxide, ||
sulfur ||dioxide, ||and ||chlorofluorocarbons ||(CFC's)
Water ||Pollution ||- ||CORRECT ||ANSWER✔✔-Contaminants ||enter ||water ||by ||ground ||runoff ||or ||
by ||leaching
, Thermal ||pollution ||- ||CORRECT ||ANSWER✔✔-Factories ||dump ||water ||at ||high ||temperatures ||
which ||increases ||normal ||water ||temperatures. ||This ||means ||the ||water ||can ||hold ||less ||gas, ||
disrupting ||the ||ecosystem
Greenhouse ||gasses ||- ||CORRECT ||ANSWER✔✔-I.e. ||carbon ||dioxide ||and ||nitrous ||oxide. ||
Concentration ||of ||them ||is ||increased ||by ||burning ||fossil ||fuels. ||These ||gasses ||absorb ||and ||trap
||heat, ||therefore ||warming ||the ||planet

Cell ||membrane ||- ||CORRECT ||ANSWER✔✔-a ||phospholipid ||layer ||that ||covers ||a ||cell's ||surface ||
and ||acts ||as ||a ||barrier ||between ||the ||inside ||of ||a ||cell ||and ||the ||cell's ||environment
