Question: I have a new situation: Jake and his brother Jordan both have to go to the dentist to get a tooth pulled. Jake is allergic to the anesthetic unfortunately, so he has to have the procedure done without it. Jordan isn't allergic, so he is able to get his tooth pulled after an anesthetic is injected. But I can use this background: When you go to the dentist to get a tooth pulled, you really don't want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain at least not until the anesthetic wears off. What is an answer for this question: Who will not experience a disruption of ion movement in their cell membranes?
Answer: Jake

Question: I have a new situation: Drought is major concern in the Midwest. To confront the problem scientists are trying to develop drought-resistant crops. To that end, they took a plant that was not exposed to drought. They labeled it as plant A. Then they took a similar plant, and repeatedly exposed it to drought. They labeled it as plant B. They wanted to find out what makes a plant drought-resistant. But I can use this background: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. What is an answer for this question: In which plant there would be more water loss, plant A or plant B?
Answer: plant A

Question: I have a new situation: Jerry and Gary each live in separate cities, but both run equally sized farms that grow the same produce. The cities they live in have very similar environments with the only difference being that the CO2 levels in Jerry's town are elevated, and in Gary's they are not. Jerry and Gary regularly talk on the phone and compare notes with each other since their farms are so similar. But I can use this background: Plants can grow as much as 50 percent faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions, though this assumes no change in climate and no limitation on other nutrients. Elevated CO2 levels cause increased growth reflected in the harvestable yield of crops, with wheat, rice and soybean all showing increases in yield of 1214% under elevated CO2 in FACE experiments.Increased atmospheric CO2 concentrations result in fewer stomata developing on plants which leads to reduced water usage and increased water-use efficiency. Studies using FACE have shown that CO2 enrichment leads to decreased concentrations of micronutrients in crop plants. This may have knock-on effects on other parts of ecosystems as herbivores will need to eat more food to gain the same amount of protein.The concentration of secondary metabolites such as phenylpropanoids and flavonoids What is an answer for this question: Will Jerry's water bill be higher or lower than Gary's?
Answer:
lower
