The two metabolic pathways that comprise each play an important role in their function. Answer (1 of 3): Abiotic factors in an environment include such items as sunlight, temperature, wind patterns, and precipitation, could affect sea otters or any other animal if exposed to them adversely.
By the numbers. However, hypoxia (2% O2) produced a similar level of DSB induction with respect to the protons and -rays, with a comparable RBE of 1.02.Conclusions: The RBE values of proton beams estimated from DSB induction and enzymatic DSB decreased by 16% and 12%, respectively, in the presence of DMSO. The oceans absorb far more carbon dioxide than the atmosphere because most of the CO 2 that diffuses into the ocean reacts with the water to form carbonic acid and bicarbonate. Wilmers, Estes, a professor of ecology and evolutionary biology, and their co-authors, combined 40 years of data on otters and kelp bloom from Vancouver Island to the western edge of Alaska's Aleutian Islands. There is evidence that sea otters can stay submerged for more than 5 minutes at a time. Kelps and macroalgae also contribute to oxygen generation by photosynthesis, which is a necessary step in the growth process. Which had forced the sea otters to change their diet to include small sea animals. Sem categoria. Starting from the sun, create a food chain including at least three organisms. Effects of the Environment on the Sea Otter The heaviest members of the weasel family, sea otters are also the second smallest of the marine mammals. This second prospect has the greatest potential to decrease atmospheric carbon levels, as carbon could remain trapped in plant tissues at the bottom of the sea for decades or centuries.
