Question: You are given a new situation: Thomas and Alexander are freshman students in an introductory chemistry laboratory course at their local college. In this week's experiment, both Thomas and Alexander will be starting their experiments with liquid water. They both follow different experimental protocols, and at the end of the experiment Thomas discovers ice in his reaction flask, while Alexander discovers steam in his reaction flask. and a hint : As Figure above shows, the distance between particles is much smaller for the solid and liquid states than for the gas state. In the solid state, particles are fixed in place, while particles are more free to move in the liquid and gas states. The particles in the solid and liquid states "stick together," but in the gas state, they move freely about the container. In general, it requires energy to separate individual particles. If we want to make a solid adopt a liquid form, we can add energy in the form of heat, increasing the temperature of the substance. Conversely, if we want to convert a substance from a gas to a liquid or from a liquid to a solid, we remove energy from the system and decrease the temperature. Pressure also plays an important role in changes of state, which will be discussed later on. We will study these difference in greater detail in the chapter States of Matter. Please answer this question : Which person created a substance with particles that have more freedom to move than they did originally?
Answer: Alexander

[Q]: You are given a new situation: Dan and Fred were friends. they studied Biology at the same University. Fred studied bird reproduction this semester, while Dan studied fish reproduction. and a hint : Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. Please answer this question : Which friend studied more about female fish releasing very high numbers of eggs?
****
[A]: Dan

input: Please answer the following: You are given a new situation: The marine biologists studied two areas of the Black Sea. Area A, situated at the mouth of the Danube River, which presented high levels of water stratification, because of the fresh water discharged by the river; and area B, situated 35 miles south, where the water was less stratified and more oxygenated. and a hint : Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] Please answer this question : Which of the two areas had less dense water?
++++++++++
output: Area A

Please answer this: You are given a new situation: While drinking coffee John added some sugar and cream in his coffee. He started to ponder how solutes dissolve in a solvent. To that end, he added solutes in a solvent in six different conditions, case A, case B, case C, case D, case E, and case F. In case A he stirred the solution, but in case B he didn't stir the the solution. In case C he heat the solution up, but in case D he cooled the solution down. In case E he used finely ground solute, but in case F he used cubes of solute. and a hint : When you add sugar to a cold drink, you may stir it to help the sugar dissolve. If you don't stir, the sugar may eventually dissolve, but it will take much longer. Stirring is one of several factors that affect how fast a solute dissolves in a solvent. Temperature is another factor. A solid solute dissolves faster at a higher temperature. For example, sugar dissolves faster in hot tea than in ice tea. A third factor that affects the rate of dissolving is the surface area of the solute. For example, if you put granulated sugar in a glass of ice tea, it will dissolve more quickly than the same amount of sugar in a cube. That's because granulated sugar has much more surface area than a cube of sugar. You can see videos of all three factors at these URLs Please answer this question : In which case the solute would dissolve slower, case A or case B?
++++++++
Answer: case B

Problem: You are given a new situation: The students studied two ponds. Class A studied a pond filled with protozoa, while class B studied a pond with almost no protozoa. and a hint : Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations under control. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. Protozoa are also important food sources for many larger organisms, including insects and worms. Please answer this question : Which class observed more protozoa predators keep many bacterial populations under control?

A: Class A

input: Please answer the following: You are given a new situation: Two groups of athletes were part of an experiment. Group One ran 10 miles without charging up their body with glycogen at the start of the exercise, and didn't eat or drink other supplements during the race. Group Two did everything by the book and had better overall results. and a hint : In endurance sports such as cycling and running, hitting the wall or the bonk is a condition of sudden fatigue and loss of energy which is caused by the depletion of glycogen stores in the liver and muscles. Milder instances can be remedied by brief rest and the ingestion of food or drinks containing carbohydrates. The condition can usually be avoided by ensuring that glycogen levels are high when the exercise begins, maintaining glucose levels during exercise by eating or drinking carbohydrate-rich substances, or by reducing exercise intensity. Please answer this question : Which group had more runners experiencing the bonk?

One
