In addition to a sea floor mapping project, the researchers will make chemical analyses of water samples that will help them determine the temperature, salinity and composition of a strong circumpolar current that flows around the boundary of the Arctic Ocean.

On average, the composition of Holstein milk is 87.7 percent water, 3.7 percent milk fat and 8.6 percent skim solids.

Instead, differences in composition between warm-water and cold-water ion channels were the result of a phenomenon called RNA editing, in which special enzymes alter the structure of the RNA messenger, and thus of the final protein.

Another proposed law would seek to water down the legal fraternity's control over judicial appointments by making a slight change in the composition of the Judicial Appointments Committee.

As an explanation for the conundrum of the ice ages, this notion could only hold water if a mechanism for such large changes in atmospheric composition might be found in the real world.

Indeed, a calculation Dr Ip performed, based on the volume and composition of the urine he collected in the plastic buckets, and of the head-dunking water at the end of each day, suggested that only 6% of the urea excreted by the turtles was leaving them in the traditional manner, via urine.
