The academic units at Michigan do a good job in appealing to their constituent groups . We will continue to pursue initiatives in energy conservation , e-procurement and electronic reverse auctions , administrative streamlining , and seeking ways to reduce costs in our health benefits programs . If all pathogens used only the H antigen to infect cells , then there would be a selective pressure for everyone in the population to have only A or B antigens , but since there are pathogens that use H , A or B for infection , the population can survive by having some individuals with no H , some with no A and some with no B antigens . For example , prostate cancer can spread to bone and breast cancer can spread to the lymph nodes . No animal species ( even apes ) has proven to be as sophisticated with language use as humans , so it has been difficult to study brain mechanisms in animals . Every time a suubmersible dives to the deep ocean floor on a biological project , they expect to find new organisms in this unexplored ecosystem . In order for science to work as a tool for gathering knowledge we must admit two assumptions . Originally , it referred to abnormal plant organs or tissues but the preferred term for that is now hyperhydricity . We're also investigating the use of Master Maintenance Agreements for all types of University-owned equipment .
