Carries copies of the instructions for assembling proteins: messenger RNA

sections of an mRNA molecule that are removed: introns
Sections of an mRNA molecule that are not removed, and are joined together to form the completed molecule: exons
1. fossils and chemical isotopes found in sediments and glacial ice
By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.
2. decrease in mortality because winter is warmer
The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm.
Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.
