1. The following questions are about climate change. Circle the right answer in the parentheses. (a) Most of the recent global warming is due to an enhanced greenhouse effect caused by increasing levels of greenhouse gases, such as (CO2, 02) (1 point) (b) (External, Internal) causes of climate change are those that alter the total amount of energy the climate system holds, whereas (external, internal) causes of climate change are those that redistribute energy within the climate system. Changes in...

Q4.23. Some researchers have hypothesized that the feedback loop pictured below influences the carbon dynamics of Arctic ecosystems as follows: Elevated atmospheric CO2 levels cause the climate to warm, thawing permafrost. Nitrogen mineralization is then stimulated as thawed permafrost decomposes. The resulting increase in soil ammonium then stimulates primary production, which pulls CO2 from the air. What kind of feedback loop is described? Temperature-Mineralization Feedback Co, Level us Primary Production Temperature N- Mineralization A positive feedback loop that amplifies the...

Choose 1 of the 4 areas addressed below and discuss: the driver, one possible exposure, a related health outcome and impact : Vectors (mosquitoes, ticks, and fleas) can carry infective pathogens such as viruses, bacteria, and protozoa, which can be transferred from one host (carrier) to another. The seasonality, distribution, and prevalence of vector-borne diseases are influenced significantly by climate factors, primarily high and low temperature extremes and precipitation patterns. While climate variability and climate change both alter the transmission...

36. The dissolution of quartz in H2O can be represented by the following reaction: SiO2 (s) + 2H2O → H4SiO4 (aq) Rimstidt and Barnes (1980) determined the reaction rate for the dissolution of quartz as a function of temperature. Their data are listed in the following table: Temperatures and Reaction Rates for the Dissolution of Quartz T(°C) k(sec-1) 65 105 145 170...

Exercise 4: Annual Precipitation Repeat the procedures of Exercises 1, 2, and 3 using the anmual precipitation totals from the Downtown Los Angeles webpage. These data can be found under the section headed "Period of Record." From there, they are located under the "Precipitation" category and Monthlhy Precipitation Listings." Use the "Monthly Totals" rather than the "Daily Extremes. (Remember, though monthly data are provided you will be working with the annual...

Question 23 (1 point) Which observation is NOT explained by the intermediate disturbance hypothesis In the interior of an old forest a low number of K-type species dominate the community Species evenness is larger when disturbances are extremely frequent Species richness increases immediately after a disturbance such as a fire, but may decrease later In beach dune environments, a low number of r-type species dominate the community Question 24 (1 point) Some birds follow moving swarms of army...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
