a biologist counts the number of zebras in a population each year, and notices an increase in the zebra population. which describes the biologists actions?\n○ graphing\n○ inference\n○ observation\n○ interacting
Answer
Brief Explanations:
The biologist is simply noting the number of zebras and the change in population over time by counting and seeing the increase, which is observation. Graphing involves creating a visual - graph, inference is drawing conclusions beyond direct observation, and interacting implies some form of engagement with the zebras other than just counting and noticing.
Answer:
observation
