A: Fiction. Antibiotics used in animals are the cause of major human drug resistant diseases. Myth: âAnimal antibiotics kill more people than breast and prostate cancerâ screamed a blogger in the wake of an AP story on antibiotics used to keep food animals healthy.
Mineral Luster. Luster is a description of the way a mineral surface looks when light reflects off of the surface. Luster has two categories, metallic and nonmetallic.
Sunlight bounces off white really well, so a lot of the sun's radiation that impin â¦ ges on the poles of the earth is reflected back into space. As seasons change, the area of white at the poles changes, but it is still the best natural reflector of sunlight on the planet.his is called the luster of the mineral.   The luster of a mineral is the way its surface reflects light. Most  terms used to describe luster are self-explanatory: metal â¦ lic,  earthy, waxy, greasy, vitreous (glassy), adamantine (or brilliant,  as in a faceted diamond).
