input question: Chemical equilibrium was studied by French chemist Henri Le Chatelier (1850-1936), and his description of how a system at equilibrium responds to a change in conditions has become known as Le Chatelier's principle . This principle states that when a chemical system is at equilibrium and is disturbed by a stress, the system will respond by attempting to counteract that stress until a new equilibrium is established. Stresses to a chemical system include changes in the concentrations of reactants or products, changes in the temperature of the system, or changes in the pressure of the system. We will discuss each of these stresses separately. In each case, the change to the equilibrium position will cause either the forward or reverse reaction to be favored over the opposite process. When the forward reaction is favored, the concentrations of the products increase, and the concentrations of the reactants decrease. When the reverse reaction is favored, the concentrations of the products decrease, and the concentrations of the reactants increase. David was conducting experiments on chemical equilibrium in the chemistry lab. First, he took a chemical system that was at equilibrium. He labeled it as case E. Then he changed the temperature of the system. He labeled that experiment as case T. Finally, he observed two more experiments, case A and case B. In case A forward reaction was favored, and in case B reverse reaction was favored. In which case the products concentration would decrease, case A or case B????
output answer: case B

Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished. Two researches studied adolescents during puberty. Tim studied males, while Dan studied females. Which researcher observed that the growth spurt is triggered by testosterone?
----
Answer: Tim

Q: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease. Margaret is a sophomore in high school who just started her Spring break. With a week off from school, her family is spending some time driving out of state to visit her grandma, Kathy, who has a cabin up in the snowy mountains. Margaret always enjoys spending time with her grandma because she has interesting stories and makes some of the best pie around. Also, they always go skiing when visiting the cabin so Margaret is excited for that. Who would be less likely to get lost on the mountain?
A: Margaret

Question: Gibberellins are hormones that cause the plant to grow. When gibberellins are applied to plants by scientists, the stems grow longer. Some gardeners or horticulture scientists add gibberellins to increase the growth of plants. Dwarf plants (small plants), on the other hand, have low levels of gibberellins ( Figure below ). Another function of gibberellins is to stop dormancy (resting time) of seeds and buds. Gibberellins signal that it's time for a seed to germinate (sprout) or for a bud to open. Two teams of agriculturists used different methods to improve production. Team Corn used organic methods, and team Plum used gibberellins for their crops. Which team stopped dormancy (resting time) of buds?
Answer: Plum

[Q]: You don't have to suffer through an infection to gain immunity to some diseases. Immunity can also come about by vaccination. Vaccination is the process of exposing a person to pathogens on purpose so the person will develop immunity to them. In vaccination, the pathogens are usually injected under the skin. Only part of the pathogens are injected, or else weakened or dead pathogens are used. This causes an immune response without causing the disease. Diseases you are likely to have been vaccinated against include measles, mumps, and chicken pox. In Colorado, everyone makes sure they get vaccinated for measles. However in Ontario they don't like to get vaccines so most of the population skips them. One year a major measles outbreak occurs. Will the population of Colorado have a higher chance or lower chance of contracting measles?
****
[A]: lower

Problem: Given the question: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. Two twin brothers live far away from each other. Dan lives in the Norther Hemisphere, in North America, and Bill lives in Tasmania, in the Southern Hemisphere.They often talk about the weather, the seasons, and how it affects them. Which brother experiences less sunlight in June?

The answer is:
Bill
