In order to test the effect of an antibiotic on bacterial growth, a scientist cultured 1 species of bacteria in 50 containers. In 10 containers, he added 5 mg/L of the antibiotic. In 10 other containers, he added 10 mg/L of the same antibiotic. In 10 other containers, he added 20 mg/L of the antibiotic. In 10 other containers, he added 25 mg/L of the antibiotic.
