The most stable of niobium's isomers is 93m Nb with a half-life of 16.13 years. The least stable isomer is 84m Nb with a half-life of 103 ns. All of niobium's isomers decay by isomeric transition or beta decay except 92m1 Nb, which has a minor electron capture decay chain.
Sunflower (photo by Yves Couder) Why is it that the number of petals in a flower is often one of the following numbers: 3, 5, 8, 13, 21, 34 or 55? For example, the lily has three petals, buttercups have five of them, the chicory has 21 of them, the daisy has often 34 or 55 petals, etc. Furthermore, when one observes the heads of sunflowers, one notices two series of curves, one winding in one sense and one in another; the number of spirals not being the same in each sense.
A daisy is two flowers in one, a design that attracts bees. The existence of flowering and fruiting plants depends on outside forces that act as pollinators. Plant pollen is dropped from flower to flower, carried by the wind or rain, or moved from one place to another by birds and insects.Within the insect world, bees are the primary pollinators and are responsible for the propagation of many types of plants and flowers, including daisies.ith flowers that grow close to the ground such as daisies, the process goes on in full view, as bees move from blossom to blossom transporting pollen between the male and female reproductive organs of the plants.
