why are chili peppers hot - CORRECT ANSWERS ✔✔they
|\ |\ |\ |\ |\ |\ |\ |\ |\
have capsaicin- makes them hot, keeps herbivores away
|\ |\ |\ |\ |\ |\ |\
define ecology - CORRECT ANSWERS ✔✔scientific study of
|\ |\ |\ |\ |\ |\ |\
interactions between organisms
|\ |\ |\
hypothesis - CORRECT ANSWERS ✔✔H0= null |\ |\ |\ |\ |\
HA= regular hypothesis
|\ |\
observation - CORRECT ANSWERS ✔✔-collect |\ |\ |\ |\ |\
observational data |\
-causation doesn't=correlation |\
-advantages= you can go out and collect it, lots of data |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
-disadvantages= don't always know the direct cause, just |\ |\ |\ |\ |\ |\ |\ |\
know correlation |\
manipulative experiment - CORRECT ANSWERS ✔✔can |\ |\ |\ |\ |\ |\
control a factor |\ |\ |\
-advantage=used to test cause and effect, can apply |\ |\ |\ |\ |\ |\ |\ |\
known treatments |\
,disadvantages= they don't account for other natural |\ |\ |\ |\ |\ |\ |\
variables, and hard to conduct on larger scales
|\ |\ |\ |\ |\ |\ |\
natural experiment - CORRECT ANSWERS
|\ |\ |\ |\ |\
✔✔observational
-advantages= can be done on small or large scales, no |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
manipulation
-disadvantages= don't know the direct cause and effect, |\ |\ |\ |\ |\ |\ |\ |\
can't control other variables
|\ |\ |\
model - CORRECT ANSWERS ✔✔a mathematical
|\ |\ |\ |\ |\ |\
conceptualization
sampled data, modeled projection
|\ |\ |\
dependent & independent variable - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\
✔✔dependent= the effected object for. which one is |\ |\ |\ |\ |\ |\ |\ |\
trying to find the cause (y)
|\ |\ |\ |\ |\
independent= the predictor variable that is the cause of
|\ |\ |\ |\ |\ |\ |\ |\ |\
the occurrence (x)
|\ |\
causation- correlation - CORRECT ANSWERS ✔✔causation
|\ |\ |\ |\ |\ |\
doesn't = correlation
|\ |\
, could be other factors
|\ |\ |\
confounding factor - CORRECT ANSWERS ✔✔outside |\ |\ |\ |\ |\ |\
influence that has effect on an experiment
|\ |\ |\ |\ |\ |\
treatment - CORRECT ANSWERS ✔✔combinations of
|\ |\ |\ |\ |\ |\
factor levels |\ |\
treatment group in an experiment receives the treatment
|\ |\ |\ |\ |\ |\ |\ |\
(test subjects)
|\
control - CORRECT ANSWERS ✔✔group that doesn't
|\ |\ |\ |\ |\ |\ |\
receive the variable testing, doesn't receive the
|\ |\ |\ |\ |\ |\ |\
treatment
replication - CORRECT ANSWERS ✔✔repeating an
|\ |\ |\ |\ |\ |\
experiment or getting the same results over and over
|\ |\ |\ |\ |\ |\ |\ |\
randomization - CORRECT ANSWERS ✔✔choosing things |\ |\ |\ |\ |\ |\
randomly, assigning them randomly, so as not to
|\ |\ |\ |\ |\ |\ |\ |\
influence the experiment |\ |\
