EEE 304 LAB SHEET PRACTICE
EXAMINATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ [LAB 7] For circuit 1: what type of filter is it?.
Answer: low-pass filter
◍ law and theory.
Answer: -law:states pattern in nature-theory:explains law by providing an
explanation of how or why the pattern in nature occurs-law of gravity
-theory of relativity -theory does not become a law because they are
different -have same validity
◍ lab 2 procedure.
Answer: -treat sowbug carefully(place back with food when not used)-petri
dish with 10 sowbugs,observe their appearance;draw and label-observe
behavior for 5 minutes;note it-ind:environment-dep:response to each
environment -null:environment doesn't effect behavior
-alternative:environment had effect on behavior -place clean towel in each
side of petri dish(flat),squirt one side with water,align openings and tape
together,put bugs in each side with separator between them(put lids
on),count # of bugs in each side every 30 seconds for 10 minutes and grab in
table 1,get class data-ind:moisture (1o minutes on graph)-student
design;state problem investigating,write null and alternative,get
approval,test hypothesis, record data on sheet 2,get class results,write lab
report-wash all equipment used,put all materials back,wipe table with
alcohol,clean common ares,she instructor
◍ [LAB 1] Remove R3 from the circuit and note the voltage drops between
node C and D, and D and
A. Does the resistance of the whole circuit increase or decrease?.
, Answer: increase
◍ [LAB 4] Does the voltage you measured in Q7 matches what you measured
in Part A Q3?(little difference is acceptable).
Answer: yes
◍ lab 3;pre-lab.
Answer: -download and print cell micrographs-4 things needed for
microscope storage-what safety equipment is needed (gloves,googles)-why
might cell theory be a law (shown to be true through research and
trials)-craw prokaryotic and eukaryotic cells and label distinguishing
features (nuclei,flagellum,mitochondria,nucleus)-how does endosymbiotic
theory explain presence of plasma membrane bound organelles (all
eukaryotic cells have prokaryotic cells inside their
cells)-prokaryotic:bacteria and archer-eukaryotic: eukaryote (related to
archea)-idnetify domains of cheek
cells,bacteria,elodea,potato,onion,yeast-present in plant cells not
animal(chloroplasts)-plant&fungi:smaller cells,one prokaryotic and one
eukaryotic -animals and fungi closely related -cheek cells .vs. eodea: one
dot,many dots;cheek rounded,elodea rectangular -cellwall in plants:
structure;allows turgor pressure-animals have muscles in bone sin place of
cell wall-gloves,googles
◍ wet mount preparation.
Answer: -place clean slide on paper towel-if viewing solid:place one drop of
liquid on center then use forceps to place solid in drop-if liquid:place drop in
center using pipet, try not to stir sample,add stain if needed.-place cover slip
over specimen (avoid bubbles),drop at 45 degree angle
◍ condensor.
Answer: -lens system located below stage opening -concentrates and directs
light through specimen
◍ microscope check list for storage.
Answer: -lenses cleaned with lens paper-stage cleaned with tissue
wipes-lowest power objective in place-stage lowered-light switch off-light
