The ratio of breath alcohol concentration to blood alcohol content is 2,100:1. This means that 2,100 milliliters (ml) of alveolar air will contain the same amount of alcohol as 1 ml of blood. For many years, the legal standard for drunkenness across the United States was 0.10, but ...
cells in one channel and dead cells in the other channel as you go. Either way, write down the total for each major square, reset your counter, and move on to the next square. When finished, calculate the average number of live cells per major square and the average number of dead ...
High blood pressure can rapidly transform healthy arterial cells into inflammation-prone "foam cells" that pose an increased risk of cardiovascular-related issues.
