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.

The honey bee, Apis mellifera (L.), is our most beneficial insect. We must do all we can to protect bee colonies which are pollinators for many of our home and commercially grown fruits and vegetables. The annual contribution of honey bees to food production in the United States is estimated to be $10 billion. Normally, honey bees favor a cavity entrance that faces southeast and is about 1.5 inches (38 mm) in diameter. 2  A mature honey bee colony can range in population size of 20,000 to 100,000 bees depending on the season. 3  The colony population will peak from late spring to summer and reach a low point in winter.
