Besides, bacteria can also affect the platelet RNA content. Oxygen-16 is the dominant isotope, making up more than 99 percent of all natural oxygen; oxygen-18 makes up 0. true. Introduction. 2. Whereas, intervals of low O18 values represent a warmer climate. Isotopes are atoms of the same element that have different numbers of neutrons. There are 11 genomic islands in W224 N and most of the GIs are specific to W224 N. What happened to the composition? Remember that a greater amount of O16 than O18 evaporates. As far as I know scientists use oxygen isotope 16 to 18 ratio in air trapped in glaciers (or in old foraminiftera shells) as proxy for temperature in the past.
