Some costs have components that are fixed and some that are variable. One example is wages for your sales force. A portion of the wage for a salesperson may be a fixed salary and the rest may be sales commission.
Hornets are the largest eusocial wasps, reaching up to 45 millimetres (1.8 inches) in length. Yellowjackets are black-and-yellow wasps of the genus Vespula or Dolichovespula (some can be black-and-white, the most notable of these being the bald-faced hornet, Dolichovespula maculata).
For years the Asian Hornet has lived among inhabitants here and elsewhere across East Asia. Parts of Japan in particular have been home to significant populations for years. But they have never attacked like they are attacking now. Ren Chengan, 28, has lived on the outskirts of An Kang all his life.
