Thyroxine: A hormone that is made by the thyroid gland and is one of the most important thyroid hormones. Four iodine molecules are attached to the molecular structure of thyroxine.Along with the more powerful thyroid hormone triiodothyronine (T3), thyroxine affects almost every process in the body, including body temperature, growth, and heart rate.

But studies have shown honeybees will fly as much as 6 miles to visit a nectar source and will readily travel 2 miles.This article provides a more detailed discussion of this behavior. Ratnieks, F.

Honey bees obtain necessary vitamins from royal jelly, pollen and various microorganisms within the hive. If worker bees collect and store significant amounts of pollen, a colony has no need to seek out alternate protein sources. Honey bees collect pollen and nectar as food for the entire colony, and as they do, they pollinate plants. Nectar stored within their stomachs is passed from one worker to the next until the water within it diminishes. At this point, the nectar becomes honey, which workers store in the cells of the honeycomb.
