I am a biologist, not a rat breeder, and my interest in rat colors stems from my fascination with the biology of pigmentation. Therefore, this is not an article about rat standards! Not all rat colors are included here because I have focused my attention on the mutations whose cellular consequences are known. There are many other colors whose specific causes are not yet known.

For example, on average the ratio of blood alcohol content to breath alcohol content the partition ratio is to 1. In other words, there are parts of alcohol in the blood for every part in the breath. However, the actual ratio in any given individual can vary from Thus a person with a true blood alcohol level of.
Metabolism and excretion[ edit ] This article needs additional citations for verification. May Learn how and when to remove this template message Alcohol is absorbed throughout the gastrointestinal tract, but more slowly in the stomach than in the small or large intestine.
For this reason, alcohol consumed with food is absorbed more slowly, because it spends a longer time in the stomach. Furthermore, alcohol dehydrogenase is present in the stomach lining. After absorption, the alcohol passes to the liver through the hepatic portal veinwhere it undergoes a first pass of metabolism before entering the general bloodstream.The Black Death was one of the most devastating pandemics in human history.
The disease spread fast and covered the territory from China to England and the ultimate western part of Europe, covering almost entire Europe within several years.
The disease was a true mystery for Medieval people, whereas the medicine was under-developed to cope [ ]. The Black Death, also known as the Black Plague, was a devastating pandemic that first struck Europe in the mid-late-fourteenth century (–), killing between one-third and two-thirds of Europe's population.
Almost simultaneous epidemics occurred across large portions of Asia and the Middle East, indicating that the European outbreak was actually part of a multi-regional pandemic. Blood alcohol content (BAC), also called blood alcohol concentration, blood ethanol concentration, or blood alcohol level, is most commonly used as a metric of alcohol intoxication for legal or medical purposes..
Blood alcohol concentration is usually expressed as a percentage of ethanol in the blood in units of mass of alcohol per . Plague is an infectious disease caused by the bacteria known as Yersinia pestis.; Plague has a high fatality rate and has been described for centuries.
In the Middle Ages, plague was known as the "Black Death."It caused the death of 60% of the population of Europe during a pandemic (an epidemic of human disease that has spread through a large geographic area).
