COMPLETE PRACTICE QUESTIONS,
VERIFIED CORRECT ANSWERS AND
COMPREHENSIVE FINAL EXAM STUDY
GUIDE
Prophase I - CORRECT ANSWER --3 from mom & 3 from dad (Haploid = 3
Diploid = 6)
-longest stage How does long term memory work? - CORRECT ANSWER -
Activated when needed => pulled into short term (working) memory
Long term potentiation - CORRECT ANSWER -use of information is like a
sorting process
T/F: If information is not used, then it is discarded - CORRECT ANSWER -
True
LTP is facillitated by - CORRECT ANSWER -Chunking
Emeregnce - CORRECT ANSWER -The whole is greater than the sum of the
parts
,Emergent Properties - CORRECT ANSWER -Results from the arrangement
and interaction of parts within a system
Reductionism - CORRECT ANSWER -Reduction of complex systems to
simpler components that are more manageable to study
Scientific Method - CORRECT ANSWER -Make an observation
Do background research
Make a hypothesis
Create an experiment
Evaluate the results of the experiment
If the predictions are wrong, make a new hypothesis and start over from
step 3
Revise predictions
Repeat and verify
4 most abundant elements - CORRECT ANSWER -C, H, O, N
Ionic bonds - CORRECT ANSWER -Between atoms => the more
electronegative elements steals an electron
Van der Waals Interactions - CORRECT ANSWER --Develop because
electrons are in constant motion
-single interaction is weak but multiple are strong
,Hydrogen bonds - CORRECT ANSWER --very strong dipole-dipole
interaction
-H + F, O, N
Cohesive behavior - CORRECT ANSWER --polar molecules side with
different charges are attracted to each other
-surface tension is a measure of how hard it is to break the surface of a
liquid
Hydrophillic - CORRECT ANSWER -Ions, salts, polar, "water loving"
Hydrophobic - CORRECT ANSWER -Lipids, nonpolar, "water hating"
Organic compounds - CORRECT ANSWER --carbon based compounds
-carbon bonded to another carbon or hydrogen
Hydrocarbons - CORRECT ANSWER --only hydrogen and carbon
-nonpolar, uncharged, hydrophobic
Hydroxyl group - CORRECT ANSWER --alcohol
-polar
-form hydrogen bodns with water
-hydrophillic
, Ketone - CORRECT ANSWER --internal carbonyl group
-polar
-hydrophillic
Aldehyde - CORRECT ANSWER --terminal carbonyl group
-polar
-hydrophillic
Carboxyl group - CORRECT ANSWER --polar
-hydrophillic
-very acidic
Amino group - CORRECT ANSWER --proton acceptor => basic
-hydrophillic
Sulfhydryl group - CORRECT ANSWER --structure of some proteins
-less polar than a hydroxyl group
Phosphate group - CORRECT ANSWER --contributes a negative charge
-acidic
-hydrophillic
-phospholipids & nucleic acids
Methyl group - CORRECT ANSWER --nonpolar hydrocarbon
