Hybrid deer

A number of deer hybrids are bred to improve animal protein yield in farmed deer. American elk and Red Deer from the Old World can produce fertile offspring in captivity, and were once measured one species. Hybrid offspring, however, must be able to escape and defend themselves against predators, and these hybrid offspring are not capable to do so in the wild state. Recent DNA, animal actions studies, and morphology and antler characteristics have shown there are not one but three varieties of Red Deer. The hybrids are about 30% more efficient in producing antler by compare velvet to body weight. Wapiti have been introduced into some European Red Deer herds to improve the Red Deer type, but not always with the proposed improvement.

Both male Mule Deer/female White-tailed Deer and male White-tailed Deer/female Mule Deer matting have formed hybrids. Hybrids have been reported in the wild but are disadvantaged because they don't correctly inherit survival strategies. Mule Deer move with bounding leap to escape predators. Slotting is so specialized that only 100% heritably pure Mule Deer seem able to do it. In captive hybrids, even a one-eighth White-tail/seven-eighths Mule Deer hybrid has erratic escape performance and would be unlikely to survive to breeding age. Hybrids do survive on game ranches where both species are kept and where predators are prohibited by man.

Honey

Honey is a sweet and thick fluid produced by honey bees from the nectar of flowers. According to the United States National Honey Board and various international food system, honey stipulates a pure product that does not allow for the addition of any other substance...this includes, but is not limited to, water or other sweeteners. This article refers exclusively to the honey produced by honey bees honey twisted by other bees or other insect have very different properties. Honey is significantly sweeter than table sugar and has attractive chemical properties for baking. Honey has a typical flavor which leads some people to prefer it over sugar and other sweeteners.

Most microorganisms do not grow in honey because of its low water movement of 0.6[2]. However, it is important to note that honey frequently contains dormant end spores of the bacteria Clostridium outline, which can be perilous to infants as the end spores can transform into toxin-producing bacteria in the infant's immature intestinal tract, leading to disease and even death. The study of pollens and spores in raw honey can determine floral sources of honey. Because bees carry an electrostatic charge, and can attract other particles, the same techniques of melissopalynology can be used in area ecological studies of radioactive particles, sand, or particulate pollution.

Television

Television is a widely used telecommunication system forbroadcasting and receiving moving pictures and sound over a distance. The term "television" may also be used to refer specifically to a television set, programming or television transmission. The word is derived from mixed Latin and Greek roots, meaning "far sight": Greek τῆλε "tele", far, and Latin vision, sight .
Since it first became commercially available from the late 1940s, the television set has become a common household communications device in homes and institutions, particularly in the first world, as a source of entertainment and news. Since the 1970s, video recordings on VCR tapes and later, digital playback systems such as DVDs, have enabled the television to be used to view recorded movies and other programs.
A television system may be made up of multiple components, so a screen which lacks an internal tuner to receive the broadcast signals is called a monitor rather than a television. A television may be built to receive different broadcast or video formats, such as High-Definition television.
