During hibernation, a bear in Alaska can double its body weight. Explain how the fat gained (lipids) assist the bear during hibernation.
Lipids are used for long term energy. The bear stores fat to keep an energy source during hibernation

Water droplets hang from pine needles. Explain how cohesion and adhesion work together to keep the droplets on the needles.
Cohesion causes the droplets to form, adhesion causes them to stick to the needles
