Q: Please answer correctly the following question related to the paragraph below. Will the gas in container A have a higher or lower energy level than container B? A scientist, John, has two containers of the same noble gas. John sends electricity through container A. Just as he is about to activate the electricity for container B, the power goes out, and he is unable to do so. Frustrated, John goes to find the circuit breaker to see if a fuse has blown. Hint: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word "Open" in the sign below. Krypton gives off violet light and xenon gives off blue light.
A: higher
Question: Please answer correctly the following question related to the paragraph below. Which container will have lower solubility of the nitrogen gas? Robin is an exterminator who is making new mixtures of chemicals to use for when he gets called to kill rats in his neighborhood. To make the mixtures, he has to dissolve nitrogen gas in containers of water. In one container, container A, he dissolves the nitrogen gas under high pressure. In the other container, container B, he dissolves the nitrogen gas under low pressure. Hint: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures.
Answer: container B
[Q]: Please answer correctly the following question related to the paragraph below. Which frim's average total cost would decline, firm B or firm C? City D's mayor wants to invite more businesses in the city. Three firms, firm A, firm B, and firm C, took advantage of this opportunity. Firm A does not require large initial costs, but firm B and firm C require large initial costs. Firm B managed to increase its market share, but firm C failed to increase its market share. Hint: A firm with high fixed costs requires a large number of customers in order to have a meaningful return on investment. This is where economies of scale become important. Since each firm has large initial costs, as the firm gains market share and increases its output the fixed cost (what they initially invested) is divided among a larger number of customers. Therefore, in industries with large initial investment requirements, average total cost declines as output increases over a much larger range of output levels.

input: Please answer the following: Please answer correctly the following question related to the paragraph below. Which plant would not see increase in growth, plant C or plant D? Keith has four plants in his backyard, plant A, plant B, plant C, and plant D. Plant A is very large, but plant B is smaller. Plant C and D are the same size. He applied some gibberellins to plant C, but didn't apply anything to plant D. He got curious about why some plants are bigger, while others are not. Hint: Gibberellins are hormones that cause the plant to grow. When gibberellins are applied to plants by scientists, the stems grow longer. Some gardeners or horticulture scientists add gibberellins to increase the growth of plants. Dwarf plants (small plants), on the other hand, have low levels of gibberellins ( Figure below ). Another function of gibberellins is to stop dormancy (resting time) of seeds and buds. Gibberellins signal that it's time for a seed to germinate (sprout) or for a bud to open.
++++++++++
output: plant D
Please answer this: Please answer correctly the following question related to the paragraph below. Which friend studied more about fungus eating ants? Bill and Chris are passionate entomologists. Bill knows everything there is to know about most ants except the Leafcutter ants. Chris studied Leafcutter ants extensively and exclusively for years now. They are good friends and exchange ideas often over a pint of beer. Hint: Most ants are generalist predators, scavengers, and indirect herbivores, but a few have evolved specialised ways of obtaining nutrition. It is believed that many ant species that engage in indirect herbivory rely on specialized symbiosis with their gut microbes to upgrade the nutritional value of the food they collect and allow them to survive in nitrogen poor regions, such as rainforest canopies. Leafcutter ants (Atta and Acromyrmex) feed exclusively on a fungus that grows only within their colonies. They continually collect leaves which are taken to the colony, cut into tiny pieces and placed in fungal gardens. Ergates specialise in related tasks according to their sizes. The largest ants cut stalks, smaller workers chew the leaves and the smallest tend the fungus. Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is found to be toxic to the fungus, the colony will no longer collect it. The ants feed on structures produced by the fungi called gongylidia. Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi.

Question: Please answer correctly the following question related to the paragraph below. Which researcher learned more about the prevalence of AM fungi at lower soil nutrient concentrations? Greg and Paul were two neighbors. They were both into mycology. Greg researched AM fungi, while Paul studied other types of mycorrhizal fungi. Hint: 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.
Answer:
Greg
