Quiz Answers:
D 57°F
False Bees located on the surface of the winter cluster are packed tightly together forming an insulating shell which varies in thickness from 1-3 inches. The bees within the cluster are much less compact and generated heat through metabolic process. After brood production begins, the bees in the center of the cluster must also care for the brood.
True The winter cluster contracts ad expands with decreasing and increasing environmental temperatures, respectively. Heat loss is diminished by contraction of the cluster which decreases its cooling surface and increases the density of the bees making up the insulating layer.
True Heat is generated by the bees within the winter cluster. Each bee acts as a thermostat and the heating process starts in the thoraces of the bees. Heat production is achieved through the microvibration of thoracic flight muscles and can continue for long periods of time without any visible muscular movements.
True During the process of metabolizing honey, bees give off large quantities of water. In the winter it is important to get rid of this water so that it does not condense within the hive.
