However, this is not indicative of larger whales’ ability to retain heat better, as the thickness of a whale’s blubber does not significantly biology 11 mcgraw hill ryerson pdf heat loss. More indicative of a whale’s ability to retain heat is the water and lipid concentration in blubber, as water reduces heat-retaining capacities, and lipid increases them.

It is particularly important for species that feed and breed in different parts of the ocean. Blubber, however, does not compress under pressure. While diving in cold water, blood vessels covering the blubber constrict and decrease blood flow, thus increasing blubber’s efficiency as an insulator. Blubber from emaciated dolphins is a poorer insulator than that from nonpregnant adults, which in turn have a higher heat conductivity than blubber from pregnant females and adolescents. The average 70-year-old Inuit with a traditional diet of whale and seal has arteries as elastic as those of a 20-year-old resident of Denmark. The oil could serve in the manufacture of soap, leather, and cosmetics.

The chemical industry is exploring the use of renewable feed stocks to improve sustainability, prompting the exploration of bioprocesses for the production of chemicals. Attractive features of biological systems include versatility, substrate selectivity, regioselectivity, chemoselectivity, enantioselectivity and catalysis at ambient temperatures and pressures. However, a challenge facing bioprocesses is cost competitiveness with chemical processes because capital assets associated with the existing commercial processes are high. The chemical industry will probably use biotechnology with existing feed stocks and processes to extract higher values from feed stocks, process by-products and waste streams. In this decade, bioprocesses that offer either a process or a product advantage over traditional chemical routes will become more widely used.
