Toronto is home to one of the leading manufacturers of aerosol sprays in the country. Because of this, homes in Toronto often spray high levels of aerosol on a regular basis. In Saskatchewan, meanwhile, the local government enacted a ban on aerosol sprays several years ago, so their level of aerosol use is now essentially zero. Given the paragraph above, please answer correctly the following question: Which city, Toronto or Saskatchewan, will be destroying less of the ozone layer? Hint: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk.

Q: Bob and Andy are two microbiologists. They are studying bacteria: Bob studies nitrogen fixating bacteria, while Andy studies non-respiratory and facultative anaerobes. Given the paragraph above, please answer correctly the following question: Which researcher learned less about fermentation to generate energy? Hint: In many ways, bacterial metabolism provides traits that are useful for ecological stability and for human society. One example is that some bacteria have the ability to fix nitrogen gas using the enzyme nitrogenase. This environmentally important trait can be found in bacteria of most metabolic types listed above. This leads to the ecologically important processes of denitrification, sulfate reduction, and acetogenesis, respectively. Bacterial metabolic processes are also important in biological responses to pollution; for example, sulfate-reducing bacteria are largely responsible for the production of the highly toxic forms of mercury (methyl- and dimethylmercury) in the environment. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste. Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves.
A: Bob
Question: James is testing the strength of electromagnetic fields. He takes two lengths of copper wire and coils them. His first coil, A, has a weaker magnetic field than his second coil, B. Given the paragraph above, please answer correctly the following question: Will increasing the number of turns in a coil increase or decrease the strength of the electromagnetic field? Hint: The device in the circuit in Figure above is an ammeter. It measures the current that flows through the wire. The faster the magnet or coil moves, the greater the amount of current that is produced. If more turns were added to the coil, this would increase the strength of the magnetic field as well. If the magnet were moved back and forth repeatedly, the current would keep changing direction. In other words, alternating current would be produced. This is illustrated in Figure below .
Answer: increase
[Q]: There is a strange phenomenon going on in Siberia. Biologist noticed that 60 percent of the Siberian Tigers have leucism, and another 40 percent have albinism. They labeled the first group as group A and the latter one as group B. They need to find the reasons for this phenomenon. Given the paragraph above, please answer correctly the following question: Eyes not affected by loss of pigmentation may or may not be an important characteristic of which group, group A or group B? Hint: Leucism (/luszm, -kz-/)[1][2][3] is a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes.[3] It is occasionally spelled leukism. Unlike albinism, it is caused by a reduction in multiple types of pigment, not just melanin.

input: Please answer the following: Michael is planning on playing a prank on his older brother. He is going to take a bungee cord and stretch it and then release it so that it hits his older brother as he is sleeping. He is deciding whether to stretch the cord only partially or completely before releasing it. Given the paragraph above, please answer correctly the following question: Will the bungee cord resist further stretching more when it's stretched partially or completely? Hint: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL:

Paul and Dirk were studying the human digestive system. paul studied more about the stomach, while Dirk studied more about the jejunum. Given the paragraph above, please answer correctly the following question: Which student read more about villi containing many capillaries? Hint: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court!
