Creatinine is a toxin produced during the metabolism of meat in our body. Therefore, people with lots of muscles or who eat lots of meat always have a relatively high creatinine level, but it usually fluctuates in the normal range: 0.5-1.3mg/dL.
comet definition An object that enters the inner solar system, typically in a very elongated orbit around the sun. Material is boiled off from the comet by the heat of the sun, so that a characteristic tail is formed.
Comets are not meteors. Comets are like giant, dirty, exceedingly fluffy âsnowballs.â Meteors are rock fragments, usually dust particles, falling through the atmosphere. âFalling starsâ streaking through the sky at night are usually dust particles thrown off by comets years ago. In fact, every day we walk on comet dust.
