But you'll always start in the Bluetooth settings. First, launch the iPad's settings. On the left-side menu, find and tap Bluetooth..

Pollen is produced in the 'microsporangium' (contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants).
Pollen is a mass of fine spores containing the male cells of a plant. Trees, grasses and weeds release these particles in the air to fertilize other plants. However, many people are allergic to the chemicals they contain and weed pollen is one of the most common types that can trigger a seasonal allergy.
