As the NaCl moved into the potato cells, the potato increased in mass. The potatoes in the 0.025 g/mL solution increased in mass as water molecules moved into the potato cells As the NaCl concentration decreased, the mass of the potato increased as water molecules moved out of the potato cells. The potatoes in the 0.050 g/mL solution lost the greatest amount of mass as water molecules moved out of the potato cells. As the NaCl concentration increased, the mass of the potato increased as more NaCl moved into the potato cells. The potatoes in the 0.00 g/mL solution increased in mass as water molecules moved into the potato cells.

The Atlantic flyway is a bird migration route that goes through South Carolina. The tundra swan range is part of the Atlantic flyway. Each year, approximately 100,000 tundra swans migrate along this flyway from northern Alaska and Canada to the southern Atlantic coast. Most of them spend the winter in North Carolina, but several hundred tundra swans winter in the wetlands of the ACE basin in South Carolina. As birds prepare for their migration, they go through many changes.

As the time to migrate approaches, birds exhibit physiological changes, such as increased muscle mass, increased fat storage, and changes in metabolism. Although birds accumulate fat reserves of up to 50% of their body weight in preparation for departure, the rigors of long-distance flight require most birds to rest and refuel several times before they reach their final destination. Without places along the way that provide an adequate food supply for the quick replenishment of fat reserves, shelter from predators, and water for rehydration—places referred to as stopover sites—these birds would be doomed.

Which equation shows the cellular process that occurs as a bird prepares to fly thousands of kilometers?
