[Q]: I have a new situation: Jordan and Elizabeth are performing a chemistry experiment for the science fair. Jordan uses a high concentration of the reactants when starting his reactions. Elizabeth uses a low concentration of the reactants when she starts her reactions. But I can use this background: Collision theory tells us that molecules need to collide in order for a reaction to take place. All else being equal, anything that increases the frequency of collisions would also increase the rate of reaction. One way to do this is to increase the concentrations of one or more of the reactants. Using a real world example, a busy freeway will experience much more frequent car collisions than a fairly empty neighborhood street. Similarly, forcing more randomly moving molecules into the same amount of space will cause an increased number of collisions over a given length of time, providing the reactants with more opportunities to transform into products. What is an answer for this question: Who will have reactions that occur at a lower rate?

input: Please answer the following: I have a new situation: Because of the weed and insect menace villagers from North village decided to use herbicide tolerant crops. South village decided to postpone a decision and kept using regular seeds. But I can use this background: In addition to insects, weeds have also been a menace to farmers - just ask anyone with a garden how much they hate weeds. They can quickly compete for water and nutrients needed by other plants. Sure, farmers can use herbicides to kill weeds, but do these chemicals also harm the crops? Can biotechnology help with this issue? Some crops have also been genetically engineered to acquire tolerance to the herbicides - allowing the crops to grow, but killing the weeds. But the lack of cost effective herbicides with a broad range of activity - that do not harm crops - is a problem in weed management. Multiple applications of numerous herbicides are routinely needed to control the wide range of weeds that are harmful to crops. And at times these herbicides are being used as a preventive measure that is, spraying to prevent weeds from developing rather than spraying after weeds form. So these chemicals are being added to crops. This practice is followed by mechanical and/or hand weeding to control weeds that are not controlled by the chemicals. Crops that are tolerant of herbicides would obviously be a tremendous benefit to farmers ( Figure above ). The introduction of herbicide tolerant crops has the potential to reduce the number of chemicals needed during a growing season, thereby increasing crop yield due to improved weed management and decreased harm to the crops. What is an answer for this question: Which village didn't reduce the number of chemicals needed during a growing season?

Please answer this: I have a new situation: Two countries were neighbors, separated by a mountain range. Ghana used fossil fuels to produce energy, but one of the consequences of that was increased air pollution and acid rain. Brunei was a country inhabited by nature lovers and tree huggers, so they were very protective of their environment. But I can use this background: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. What is an answer for this question: Which country had less precipitation that was destructive to wildlife?

Answer: Brunei
Problem: I have a new situation: Two geology students had an exam on plate tectonics. Bobby learned more about divergent tectonic plates, while Nate was more confident in explaining everything about Convergent plates. But I can use this background: Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading ridges is tectonic plate pull rather than magma pressure, although there is typically significant magma activity at spreading ridges. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed. Hydrothermal vents are common at spreading centers. Older rocks will be found farther away from the spreading zone while younger rocks will be found nearer to the spreading zone. Additionally spreading rates determine if the ridge is fast, intermediate, or slow. As a general rule, fast ridges have spreading (opening) rates of more than 9 cm/year. Intermediate ridges have a spreading rate of 59 cm/year while slow spreading ridges have a rate less than 5 cm/year. What is an answer for this question: Which student knew more about Hydrothermal vents?

A: Bobby
Problem: Given the question: I have a new situation: 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. But I can use this background: 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] What is an answer for this question: Which lake had more dense layers of water?

The answer is:
High lake
Problem: I have a new situation: Carrie bought two parcels of farmland. The Northern one had soil with lots of arbuscular mycorrhizal fungi, while the Southern parcel had almost no traces of AM fungi. But I can use this background: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. What is an answer for this question: Which parcel had fewer species of AM fungi in its soil?

A:
Southern
