BIO 189 Final Review Questions With
Correct Answers
why correlation does not necessarily mean causation? - CORRECT
| | | | | | | | |
ANSWER✔✔-When we say that correlation does not imply causation, | | | | | | | | |
we mean that just because you can see a connection or a mutual
| | | | | | | | | | | | |
relationship between two variables, it does not mean that one is caused
| | | | | | | | | | |
by the other.
| | |
How would you recognize the difference between correlation and
| | | | | | | | |
causation in data provided to you? - CORRECT ANSWER✔✔-You are able
| | | | | | | | | |
to recognize the difference between correlation and causation in data
| | | | | | | | | | |
provided to me by analyzing the variables and looking if one variables
| | | | | | | | | | | |
affects the other and if it doesn't then there is correlation but not
| | | | | | | | | | | | |
causation
What is a hypothesis? - CORRECT ANSWER✔✔-A hypothesis is falsifiable
| | | | | | | | |
and written so that it could be found incorrect by an observation or
| | | | | | | | | | | | | |
experiment
What is a theory? - CORRECT ANSWER✔✔-A theory is a general set of
| | | | | | | | | | | | |
principles supported by evidence, it contains a high degree of certainty
| | | | | | | | | | |
and many experimental trials.
| | |
,What does falsifiable hypothesis mean? - CORRECT ANSWER✔✔-It
| | | | | | | |
means that it has some proposition to be proven wrong
| | | | | | | | |
What topics are scientists unable to design falsifiable hypothesis for?
| | | | | | | | | |
why? - CORRECT ANSWER✔✔-Anything that has do with mortality
| | | | | | | | |
because it is impossible to track it down
| | | | | | |
What an independent variable? - CORRECT ANSWER✔✔-the variable
| | | | | | | |
that you change/manipulate in the experiment
| | | | |
What is a dependent variable? - CORRECT ANSWER✔✔-the variable
| | | | | | | | |
that is being measure to determine if it is been affected by the
| | | | | | | | | | | | |
independent variable |
What is a standardized variable? - CORRECT ANSWER✔✔-Any variable
| | | | | | | | |
that stays constant through the experiment
| | | | |
What is a control group (placebo)? - CORRECT ANSWER✔✔-A group
| | | | | | | | | |
they use to compare the treatment group(s), they might remain
| | | | | | | | | |
untreated or receive a placebo(fake drug)
| | | | |
How is the scientific inquiry (the scientific method) done? - CORRECT
| | | | | | | | | | |
ANSWER✔✔--Make an observation | |
,-Ask a question
| |
-Consult prior knowledge | |
-Formulate a hypothesis | | |
-Make a predictions
| |
-Design experiment |
-Collect data and interpret data
| | | |
-Consult prior knowledge | |
-Draw conclusions
|
-Peer Review| |
-Publish
What is the blind method? - CORRECT ANSWER✔✔-A study in which
| | | | | | | | | | |
the participants in the clinical trial do not know if they are receiving the
| | | | | | | | | | | | | |
placebo or the real treatment
| | | |
Why would scientists implement the blind method in their experimental
| | | | | | | | |
design? - CORRECT ANSWER✔✔-To avoid bias in a experiment
| | | | | | | | |
What is a double blind? - CORRECT ANSWER✔✔-Study in which both
| | | | | | | | | | |
the participant and the experimenters do not know which group got the
| | | | | | | | | | |
placebo and which got the experimental treatment.
| | | | | | |
, What is a triple blind? - CORRECT ANSWER✔✔-Study in which neither
| | | | | | | | | | |
the participants, the experimenters or the data analysts know which
| | | | | | | | | |
group is which in the experiment
| | | | |
What is non polar covalentbond? - CORRECT ANSWER✔✔-when two
| | | | | | | | |
electrons are shared equally between two atoms
| | | | | |
What is a polar covalent bond? - CORRECT ANSWER✔✔-unequal
| | | | | | | | |
sharing of electrons between atoms
| | | |
What is an ionic bond? - CORRECT ANSWER✔✔-Occurs when a more
| | | | | | | | | | |
electronegative atom "steals" the other atom's electron (no sharing), | | | | | | | | |
oppose charges held them together
| | | |
How would you recognize what type of bond you are seeing between
| | | | | | | | | | | |
two atoms? - CORRECT ANSWER✔✔--By definition a ionic bond is
| | | | | | | | | |
between two particles of opposite charge while a covalent is between
| | | | | | | | | | |
two nonmetals.
| |
-We can also look at their electronegativity. You subtract their negativity
| | | | | | | | | |
and put them in one of this categories:
| | | | | | | |
0.0-0.3=non-polar covalent |
0.4-1.7= polar covalent | |
1.7 and greater= ionic bond
| | | |
