Katie designed an experiment using a paint roller pan, sand, and water. The steps of the experiment are listed below.

*Put 3 inches of moist sand on a paint roller pan.
*Make a beach by scooping the sand toward the higher portion of the pan.
*Pour water into the deeper end of the pan.
*Use a straw to blow (simulate wind) on the water for 2 minutes to create waves.
*Observe how the sand is displaced by the waves.

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.
