Want to know:
To prepare for an experiment, ten different sources of food were sterilized and kept in a sterile container. Bacteria of the same species were placed on each of the ten different food sources and kept at 26°C for two days. During this time, bacteria grew in nine of the containers. Based on this observation, the scientist could conclude that (1) all ten food sources used in the experiment are capable of supporting this species of bacteria (2) the temperature varied greatly in nine of the containers during this experiment (3) only the container that failed to grow any bacteria was prepared correctly (4) this species of bacteria synthesizes enzymes needed to digest the food in nine of the ten containers
