the keeling curve plotted at Mauna Loa observatory for measuring co2 it can be seen that level increases from October to May and little less in May to October so the above statement is TRUE.
this is because winter is in between October to May and during winter season there is very less photosynthesis so less absorption of co2 by the plant as a result concentration increases.
QUESTION 10 True or false: Co2 concentrations will be LOWER in September 2019 than they are...
1. Chapter: 12 Lesson: 6 Question: In 2011, the concentration of CO2 in the atmosphere as measured at the Mauna Loa Observatory exceeded 400 ppm. If the barometric pressure at that time had been 0.977 atm, what was the partial pressure of CO2 in the atmosphere (using 400.0 ppm as the concentration of CO2(g))? A 391 atm B. 5.14x10 atm C. 2.97 10-atm D. 4.00 x 10 atm E. 3.91 x 10 atm
True or false? True False 14:0 (n-tetradecanoic acid) will have a lower melting temperature than 18:0 (n-octadecanoic acid).
Concentration of CO2 in the Atmosphere Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now nearing 400 ppm. Table 1 shows the rapid rise of CO2 concentrations over the last 50 years, also available in CarbonDioxide.1 We can use...

Question 6 2 pts The nominal GDP can be lower for a given year than the real GDP. For example, if the real GDP in 2019 for a country is $50,000,000, we know the nominal GDP in 2019 for that country can be something below $50,000,000 True False
D Question 8 2 pts If price is lower than average variable cost, the firm is realizing losses but should continue operating in the market. O True False Question9 2 pts If the law of one price (LOOP) is violated, arbitrage opportunities will eventually drive prices in a direction that will restore LOOP True False DQuestion 10 2 pts Revealed preferences can be either hypothetical or incentive compatible.
