- Why are controls needed when conducting scientific experiments?arrow_forwardUse the table to answer the question. In 1928, Frederick Griffith injected four groups of mice with different strains of the bacteria, Streptococcus pneumoniae. The smooth strain had a polysaccharide capsule that protected the bacteria from the mouse’s immune system. The rough strain did not have this capsule. The details of each group and the results of the experiment are shown in the table below. Bacteria After injection with bacteria Group 1 smooth strain mice died Group 2 rough strain mice survived Group 3 heat-killed smooth strain mice survived Group 4 rough strain mixed with heat-killed smooth strain mice died Which conclusion about Group 4 is MOST strongly supported by the results of the experiment?
