3 I 4 . 3 1 THE SEARCH FOR LIFE CONTINUES Scientists have identified two similar molecules as water-like candidates to search for on other planets: methane and methanol. Answer the questions below, to help explain the importance of the investigation. Methane, CH, Methanol, CH,0 H. H. H-C-H H-C- H. 24. List three properties scientists should observe or measure for these substances. 25. Explain your choices from #24: how do these properties relate to a substance's importance for life? 26. What results should scientists see for each of these properties if the substance is similar to water? 27. Which substance, methane or methanol, do you think would show the results you predicted in #26?
