Hemlocks are a common type of tree in the northern forests of the United States. In studying one forest, a forester noticed that mature hemlocks were abundant but there were very few young hemlocks. She wondered why there were so few young hemlocks. by reading the records that other foresters in that area had kept, she learned that the population of deer living in the forest had doubled in the last five years. By reading studies on forests that other scientists had performed, she also learned that deer in similar forests like to eat young hemlocks and the young trees of other species.
which question most closely relates to the forester's observations and the collected scientific data on forests?
A. Do the young hemlocks have a disease?
B. Are deer eating most of the young hemlocks
C. Did a lack of rain the hemlocks to stop producing?
D. Why were there so many deer in the forest?
In the scenario, the forester wonders why one forest had mature hemlocks and very young hemlocks. Which part of a scientific method does this best illustrate?
A. forming a hypothesis
B. making an observation and asking a question
C. communicating the results of a study
D. setting up an experiment
Which statement is a hypothesis that would address the question are deer eating the young hemlocks and preventing them from growing?
A. Deer will eat young hemlocks but not old hemlocks
B. if the hemlocks are nasty to the deer the deer will eat them
C. if deer are eating young hemlocks then keeping deer away from the young trees will allow the trees to grow
D. deer are eating young hemlocks
