Problem: You are given a new situation: John designed a hypothetical lever that would have ideal mechanical advantage. He labeled the lever as lever A. He then wanted to compare this lever with a real world lever, which he labeled as lever B. He intended to use these levers to increase force. and a hint : The Table above includes the ideal mechanical advantage of each class of lever. The mechanical advantage is the factor by which a machine changes the input force. The ideal mechanical advantage is the increase or decrease in force that would occur if there were no friction to overcome in the use of the machine. Because all machines must overcome some friction, the ideal mechanical advantage is always somewhat greater than the actual mechanical advantage of the machine as it is used in the real world. Please answer this question : Which lever would produce greater increase in force, lever A or lever B?

A: lever A

Problem: You are given a new situation: Students working on their thesis for graduate school decide that they will write about the differences between two identical plants, but they will infect one of the plants with a fungus. This fungus will create a mycorrhizal association between one of the plants and the fungus. After caring for the plants, the students have grown fond of them and given them names. They have named one of them Audrey and the other Baudrey. They flip a coin to decide which plant will be infected with the fungus, and fate has decided that Audrey will have the fungus grow on it. Baudrey will be left to grow naturally. and a hint : 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. Please answer this question : Which plant's roots will have more surface area?

A: Audrey

Problem: You are given a new situation: Park farm and Fiddle farm provided Red city with tonnes of produce annually. Fiddle farm used and abundance of fertilizers and pesticides, while Park farm didn't use any of those substances. and a hint : Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. Please answer this question : Which farm caused more fertilizer to dissolve in the soil because of rain?

A: Fiddle

Problem: You are given a new situation: John enrolled in a prestigious culinary school. In the very first day his instructor was showing different processes used on fruits. One of them was glace fruit. He showed the class how to prepare glace fruit and kept some of the glace fruits on bowl A. To compare glace fruits with non glace fruits he kept some non glace fruits on bowl B. and a hint : Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] Please answer this question : Which fruits would not develop unfavorable osmotic pressure, bowl A or bowl B?

A:
bowl A
