Increasing levels of carbon in the atmosphere have been linked to changes in the global climate patterns.  You will be asked about this in the next questions.  We also talked about more direct impacts of higher atmospheric carbon levels on living systems (I included them in the Nutrients - Bioshpere lecture).  Describe one non-global climate change (something that does not involve a change in temperatures or rainfall) impact on the ecology of living systems and how increasing carbon levels in the atmosphere cause this impact.

Marine biology question 6) Just before the beginning of the fishing season you capture, tag, and release 4500 adult cod (Gadus morhua) from the Barents Sea. At the end of the season you learn from the United Kingdom Trawler Fleet working these waters that a total 195,500 fish were taken in the season, of which 1,950 fish were found bearing your tag. From these data calculate the “fishing ratio”, also known as the rate of exploitation, of this fishery. What was the size of the cod population actually available to this fishery at the beginning of the season?

The U.S. Department of the Interior filed an environmental impact statement (EIS) with regard to its proposal to lease approximately eighty tracts of submerged land, primarily located off the coast of Louisiana, for oil and gas exploration. Adjacent to the proposed area is the greatest estuarine coastal marsh in the United States. This marsh provides rich nutrients for the Gulf of Mexico, the most productive fishing region of the country.The EIS focused primarily on oil pollution and its negative environmental effect. Three conservation groups contend that the EIS is insufficient in that it does not properly discuss alternatives. The government contends that (a) it need only provide a detailed statement of the alternatives, not a discussion of their environmental impact, and (b) the only alternatives the NEPA requires it to discuss are those which can be adopted and implemented by the agency issuing the impact statement. Is the government correct in its contentions? Why?

Please help me with these those are answer of these statements

The concept of surface area to volume ratio can be applied to multicellular organisms. Using yourunderstanding of the surface area to volume ratio, explain why moving from the equator towards theNorth Pole, bears (Sun bear, Panda bear, Black bear, Grizzly bear, and Polar bear) increase in size.

Question 46 All of the following characteristics would define a boreal forest EXCEPT one of the largest biomes in terms of square miles of area conifers, pines, and spruce trees are very prevalent very moist because of permafrost, despite a lack of abundant precipitation usually located within 10 degrees of the equator
