Problem: Given the question: I read this background article the other day: Sodium and potassium are two of the most important elements in living things. They are present mainly as positively charged ions dissolved in water. The sodium-potassium pump moves sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. In both cases, the ions are moving from an area of lower to higher concentration. Energy in ATP is needed for this "uphill" process. Figure below shows how this pump works. Trace these steps from left to right in the figure I am facing a new situation today: Ben and Andy studied minerals and micro-nutrients. Ben studied more about magnesium, zinc and molybdenum, while his buddy Andy studied about sodium and potassium. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person studied more about Energy in ATP ?
++++++++++++++++++++++++++++++++
The answer is:
Andy
input question: I read this background article the other day: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] I am facing a new situation today: High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which lake had fewer dissolved nutrients????
output answer: High lake
I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Bend city used a lot of fossil fuels to generate electricity. Hop city, another city from the same county, used only alternative sources of energy. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city disrupted more ocean food webs?
----
Answer: Bend
Q: I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Keith is an environmental scientist. He was studying the loss of ozone layer and its effect on different species. His data showed that in the beginning or twentieth century there were hardly any loss of ozone layer. He categorized that time period as time A. Further inquiry revealed that things didn't go well at the end of twentieth century - when there were severe loss of ozone layer. He categorized that time as time B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: At what period would lower level of UV radiation reach earth, time A or time B?
A: time A
Question: I read this background article the other day: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). I am facing a new situation today: Two brothers loved geology. Bob studied sedimentary rocks while Dan studied about earthquakes and their location. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother studied more about rocks breaking as a result of stress buildup?
Answer: Dan
Please answer this: I read this background article the other day: The Figure below shows a graph of plotted against pressure for 1 mol of a gas at three different temperatures - 200 K, 500 K, and 1000 K. An ideal gas would have a value of 1 for that ratio at all temperatures and pressures and the graph would simply be a horizontal line. As can be seen, deviations from an ideal gas occur. As the pressure begins to rise, the attractive forces cause the volume of the gas to be less than expected and the value of drops under 1. Continued pressure increase results in the volume of the particles to become significant and the value of rises to greater than 1. Notice, that the magnitude of the deviations from ideality is greatest for the gas at 200 K and least for the gas at 1000 K. I am facing a new situation today: Tony is heating up a container of leftovers in his microwave for dinner tonight. When he puts the container in the microwave he leaves the lid on so it is still sealed. About two minutes into heating the food he hears a loud "pop" noise and looks to see the lid has completes blown off the container. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will increasing the temperature in a sealed container increase or decrease the pressure inside the container?

Answer:
increase
