At time there were half million Arabs in Palestine and only 70,000 Jews. Differentiate bacteria into two large groups (the Gram Positive and the Gram negative).. Gram status is important in medicine; the presence or absence of a cell wall will change the bacterium's susceptibility to some antibiotics. “We learn . . . 10% of what we read, 20% of what we hear, 30% of what we see, 50% of what we see and hear, 70% of what we discuss, 80% of what we experience, 95% of what we teach others.”. ~ William Glasser. biodistribution. and resistance selection.
