You wanted to track the spread of the invasive polyphagous shot-hole borer, so each year for the last 3 years you counted the number of trees in the Arroyo that were infested with them. This is an example of:
an experimental study
an observational study
peer review
cherrypicking data

When placing a slide on the microscope in lab ______________.
make sure that the slide is secure under the stage clips
check to make sure that the slide is not jammed under the stage clips
raise the stage to the maximum height and then place slide on the stage
