Problem: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3] Ryan explored two lakes; Big lake, and Arrow lake to the south. Arrow lake had a river flowing into it, while Big lake presented evidence of underwater geothermal activity. Many divers drowned in Arrow lake because of temperature shock. Which lake had less convection currents?

A: Arrow lake

Problem: Given the question: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. Doctors studied the blood of 2 sisters, Ann and Julie. Ann had sickle cell anemia, Julie did not. Which sister was not homozygous recessive ( ss ) for the sickle cell trait?
++++++++++++++++++++++++++++++++
The answer is:
Julie

input question: Extending the period of time over which a force acts in order to lessen the force is a common practice in design. Padding in shoes and seats allows the time to increase. The front of automobiles are designed to crumple in an accident; this increases the time the car takes to stop. Similarly, barrels of water or sand in front of abutments on the highway and airbags serve to slow down the stoppage time. These changes all serve to decrease the amount of force it takes to stop the momentum in a car crash, which consequently saves lives. Keith designs car seats. He noticed that some other car seats didn't have any padding. He marked it as case A. On the other hand, most of the seats he designed had padding. He marked it as case B. Keith needed to know pros and cons of both designs. Would case B take less or more time for the force to act than case A????
output answer: more

A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Two plants of the same type are growing near the outskirts of the Jorah forest. The first plant, colored red, is healthy and has no fungus on it. The other plant, colored black, has a fungus growing on the roots of it. These plants have been around for centuries and if crushed into a powder actually make a nice seasoning to add to a meal. Which color plant is sharing access to its glucose?
----
Answer: black

Q: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite. Ecuador and Panama both had beautiful rivers flowing into the Pacific ocean. Ecuador uses their river to dispose of their waste while Panama is very eco-friendly and doesn't do that. Which country dumps more chemicals into the ocean?
A: Ecuador

[Q]: Continued heating of the water after the ice has completely melted will now increase the kinetic energy of the liquid molecules and the temperature will rise. Assuming that the atmospheric pressure is standard, the temperature will rise steadily until it reaches 100C. At this point, the added energy from the heat will cause the liquid to begin to vaporize. As with the previous state change, the temperature will remain at 100C while the water molecules are going from the liquid to the gas or vapor state. Once all the liquid has completely boiled away, continued heating of the steam (remember the container is closed) will increase its temperature above 100C. To reenact James Watt's experiment, John sealed some water in a container. He called this stage of his experiment as stage A. Then he started heating the water in the sealed container. He labeled this stage as stage B. Once the temperature reached hundred degree centigrade, he added more heat to it. He called this stage as stage C. Once all the water has turned into steam, he kept adding heat to it. He called this last stage of is experiment as stage D. At which stage the water would bigin to vaporize, stage B or stage C?
****
[A]:
stage C
