photosynthetic organisms
they intake from the environment CO2 as a carbon source and convert it into Carbohydrates to produce energy. They use this energy to synthesize structural and functional units.
CO2 in the atmosphere is absorbed by and converted into biomass. the ozone layer photosynthetic organisms...
hat is the role of Ozone layer in earth's atmosphere?
During the Precambrian, the development of the ozone layer helped A) primitive organisms on Earth's surface to nucleate. B) shield Earth's surface from harmful ultraviolet radiation. C) promote the emergence of stromatolites. D) promote the development of anaerobic organisms.
Ozone (O3) in the atmosphere can be converted to oxygen gas by reaction with nitric oxide (NO). Nitrogen dioxide is also produced in the reaction. What is the enthalpy change when 8.50L of ozone at a pressure of 1.00 atm and 25°C reacts with 12.00 L of nitric oxide at the same initial pressure and temperature? [∆H°f (NO) = 90.4 kJ/mol; [∆H°f (NO2) = 33.85 kJ/mol; ∆H°f (O3)= 142.2 kJ/mol] [O3 + NO O2 + NO2] show all work...
Choose which of the following statements are true with regard to the hole in the ozone layer. Items (6 items) (Drag and drop into the appropriate area below) The hole in the ozone layer is caused by chlorofluorocarb ons (CFCs) emitted by some industrial practices. The hole in the ozone layer is located over eastern Europe in the northern hemisphere. The Montreal Protocol is the agreement to reduce the use of CFCs. The Kyoto Protocol is the agreement to reduce...
a-if you used a can of spray paint to write "save the ozone layer!" on the wall why would this be funny? b-what causes Aurora Borealis and Aurora Australis? c-what causes the polar ozone holes? d-describe the regions of the Earth's atmosphere. e-how do volcanic eruptions affect the climate what is the greenhouse effect? what characteristic makes a gas a greenhouse gas? f-describe three human activities that generate CO2 and list two mechanisms for the uptake of CO2 g-briefly describe...
1. Carbon-14 atoms produced in the upper atmosphere combine with oxygen to yield 14CO2, which slowly diffuses into the lower atmosphere, where it mixes with ordinary 12CO2 and is taken-up by plants during photosynthesis. When these plants are eaten, carbon-14 enters the food chain and is ultimately distributed evenly throughout all living organisms – so an equilibrium is established between the amount of C-14 consumed by the organism and the amount that is lost through exhalation of CO2 and excretion....
Despite large concentrations of CO 2 released by human activity, atmospheric CO 2 is not as high as some would expect. Studies suggest the reason for this is A addition of new carbon sinks, such as large scale agricultural fields. B increased evapotranspiration activity by phytoplankton. C uptake of CO2 by oceans is offsetting atmospheric increases. D a so-called lag in atmospheric increases in CO2 caused by global circulation. E international treaties designed to combat atmospheric CO2 releases. General Circulation...

PLEASE HELPING ON EXERCISE 4! THANK YOU!
RELATED PROBLEMS:
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...
