WSU Biology 102 Final Exam Carlyole
What is a theory in science? - CORRECT ANSWER-and overarching explanation
of a variety of related observations
What is a hypothesis - CORRECT ANSWER-an educated guess about a natural
phenomenon
Science is limited to hypotheses that can be falsified. What does this mean? -
CORRECT ANSWER-That Hypotheses must be made so that they can be
proven either right or wrong, true or false.
What does it mean to say a hypothesis is falsifiable? - CORRECT ANSWER-it is
possible to imagine some observation that would show the hypothesis is false
What did the researchers need to do to determine if its is the fungus that was
causing the bats death? - CORRECT ANSWER-infect healthy bats with the
fungus and record how many of them die
What specific group was the control group designed to answer in the Bat
experiments? - CORRECT ANSWER-are bats dying from something in the
environment besides the fungus
What is pseudoscience - CORRECT ANSWER-scientific sounding claims based
on poorly constructed experiments or faulty conclusions
Do vaccines cause autism? - CORRECT ANSWER-No- but there is correlation
Which plastic recycle codes indicate the plastic may be made with BPA -
CORRECT ANSWER-3 & 7
How does BPA cause cancer? - CORRECT ANSWER-Causes eggs to divide
unevenly and results in them having too many or too few chromosomes. It effects
meiosis which is the type of cell division that begins sexual reproduction.
, What is a genetic fingerprint? - CORRECT ANSWER-a set of characteristics that
are unique to the DNA of an individual organism, obtained by analyzing small
samples of biological material such as body tissues or fluids
What is the first step to making a DNA fingerprint - CORRECT ANSWER-Do
PCR
What is the second step in DNA finger prints - CORRECT ANSWER-cut out the
samples with the same restriction enzyme
Which type of restriction enzyme would you choose when making a DNA
fingerprint - CORRECT ANSWER-one that makes a blunt cut
when doing genetic engineering how could you get the gene of interest inserted
into the bacterial plasmid - CORRECT ANSWER-cut both the gene and the
plasmid with a restriction enzyme that creates a staggered cut and then mixed
together
What system is currently being used to produce viruses for vaccines - CORRECT
ANSWER-the virus is grown in chicken eggs and harvested to make the vaccine
Which of the macromolecules is a protein - CORRECT ANSWER-Enzymes
we obtain macromolecules from our diet. which macromolecules would you get
from eating meat? - CORRECT ANSWER-protein and lipids
Which two macromolecules make up a cell membrane - CORRECT
ANSWER-phospholipids and proteins
If the water is saltier than the cytoplasm, and if water is the only thing that can
move across the cell membrane, what will happen to the cell - CORRECT
ANSWER-shrivel up as water moves out
how do the vesicles carrying materials for export find their way through the cell -
CORRECT ANSWER-travel along microtubules of the cytoskeleton using them
as a highway
