Tyrone is interested in conducting a study to investigate what type of dog food dogs prefer. He selects two brands of canned dog food: Brand A, a chicken-based dog food; and Brand B, a beef-based dog food. In the morning, he feeds 20
dogs Brand A and records how much food is left after one hour. In the afternoon, he feeds 20 different dogs, of the same
age and type, Brand B. Again, he records how much food is left after one hour. He finds that cats eat significantly more of
Brand B than Brand A.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. the ice dissolves oxygen from the air, forming a denser crystalline matrix. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.
