In an investigation into fermentation, yeast was grown in a flask of glucose solution for 20 hours at 20 °C. The graph shows the concentrations of ethanol and glucose in the flask over the period of the investigation. (Graph: x-axis Time (hours) 0-20; left y-axis Ethanol concentration (grams per litre) 0-4, drawn as a solid line rising from 0 to about 3.4; right y-axis Glucose concentration (gr…

An experiment was carried out to investigate the growth rate of pigs. They were put into five groups of eight pigs, each with the same average initial body mass. Each group was fed a diet which contained either 0, 10%, 20%, 30% or 40% faba beans. The pigs were re-weighed each day for 40 days. Which aspect of the experimental design increased reliability of the results?
