Jack's science teacher asked the class to observe the organisms in a space of 1 m2 outdoors for 10 minutes each day for a week. Before beginning his
observations, Jack needed to mark off the space.
Which of the following procedures is likely to be the most accurate?
O A. Jack will use a meter stick to measure a space of 1 m x 1 m.
O B. Jack will use a 12-inch ruler to measure a space of 1 mx 1 m.
O C. Jack will walk along the meter stick and count how many steps he
takes. He will then walk off a space of 1 mx1 m.
O D. Jack will measure a space of 1 mx 1 m on a large sheet of paper.
He will then use the paper to mark the space outside

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
