What is the difference between positive and negative feedback? - -Positive is self-reinforcing; Negative is self-dampening What is systems theory? - -Basic concepts. System- set of regularly interacting groups ...

Study guide test 2 Strategies of nucleotide synthesis: precursors, when is ribose added, how is ribose activated and added, what are first purines and pyrimidines made, how are the various forms of THF made and/or interconverted, regulation of purine synthesis (where are committed steps), how is a balance between AMP and GMP achieved, how do folic acid antagonists impair purine synthesis. • Pyrimidines: base is made before adding the ribose sugar • Purines: ribose is already present  suga...

To what extent does an understanding of feedback systems in the carbon cycle help with attempts to mitigate the impacts of climate change? correct answer: With positive feedback impacts can be exacerbated once climate change starts to occur as natural processes tend to compound one another, increasing climatic instability and the likelihood of extreme conditions. In contrast, negative feedback is likely to have a more stabilising impact by depressing rates of the natural processes and moderatin...

The U.S. emits approximately 6 gigatons of CO2 a year. If 30% of annual CO2 emissions can be sequestered in deep ocean reservoirs, how long would it take to fill the capacity of the ocean for CO2? Assume annual emissions do not change and the minimum capacity of deep ocean reservoirs from lecture notes. The deep ocean has a capacity range of 1400 – 27,000 billion metric tons of C. 30% of 6 billion is 1.8 billion tons of CO2 sequestered annually. Using the low end of the estimated capacity,...
