Question: Given the background: Most chemical reactions within organisms would be impossible under the normal conditions within cell. For example, the body temperature of most organisms is too low for reactions to occur quickly enough to carry out life processes. Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst. A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes . and the situation: Mike is a biochemist, working for a science lab. Today, he has two organisms to investigate, organism A and organism B. He notices that organism A has enzymes, but organism B lacks enzymes. He needs to figure out how these conditions would affect the organisms. Answer the following question: Would organism B see speedier or slower chemical reactions than organism A?
Answer: slower

[Q]: Given the background: Animals may avoid becoming prey by living out of sight of predators, whether in caves, burrows, or by being nocturnal. Nocturnality is an animal behavior characterized by activity during the night and sleeping during the day. This is a behavioral form of detection avoidance called crypsis used by animals to either avoid predation or to enhance prey hunting. Predation risk has long been recognized as critical in shaping behavioral decisions. For example, this predation risk is of prime importance in determining the time of evening emergence in echolocating bats. Although early access during brighter times permits easier foraging, it also leads to a higher predation risk from bat hawks and bat falcons. This results in an optimum evening emergence time that is a compromise between the conflicting demands.Another nocturnal adaptation can be seen in kangaroo rats. They forage in relatively open habitats, and reduce their activity outside their nest burrows in response to moonlight. During a full moon, they shift their activity towards areas of relatively dense cover to compensate for the extra brightness. and the situation: Nate and Andy were two zoologists. They have been studying the characteristics of nocturnal and diurnal animals. Andy studied nocturnal animals, while Nate studied diurnal animals. Answer the following question: Which zoologist learned more about animals that are active during the night?
****
[A]: Andy

input: Please answer the following: Given the background: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition. and the situation: Dan studied two groups of individuals. Group S that had sickle cell anemia, and group B which had normal hemoglobin. He was fascinated by the results. Answer the following question: Which group had fewer members that had hemoglobin S?
++++++++++
output: group B

Please answer this: Given the background: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. and the situation: Karen studied animals in school. She started studying predators for a school presentation. She liked it. Her friend Molly liked cows, sheep and other herbivores, so she decided to do a presentation about grazers, and their role in nature. Answer the following question: Which girl learned less about animals that can be keystone species?
++++++++
Answer: Molly

Problem: Given the background: Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically 2060 micrometres (0.00080.0024 in) in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains. and the situation: A scientist has just returned to the lab after working out in the field. While in the field, she collected two flowers to examine in detail. She puts the first flower, flower X, under a microscope and begins to look at it. After examination she determines it's an anemophilous plant. She then takes flower Y and repeats the same process to determine that it's an entomophilous type of plant. Answer the following question: Which flower has a more exposed stamen?

A: flower X

input: Please answer the following: Given the background: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. and the situation: Justin and Thomas are two college students conducting an experiment in their chemistry laboratory course. They are mixing together acids and bases to produce sodium based compounds. Justin conducts his reactions at a high temperature, while Thomas conducts his reactions at a lower temperature. Answer the following question: In which person's reactions will the acid and base particles be less likely to collide with each other?
++++++++++
output:
Thomas
