[Q]: Keith has four plants in his backyard, plant A, plant B, plant C, and plant D. Plant A is very large, but plant B is smaller. Plant C and D are the same size. He applied some gibberellins to plant C, but didn't apply anything to plant D. He got curious about why some plants are bigger, while others are not. Would plant A have higher or lower levels of gibberellins than plant B? Hint: 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.

[Q]: Ted and Randy liked jogging. Last week while jogging by himself, Randy experienced an unpleasant episode and was taken to the hospital, because he passed out while jogging in the heat, without any water or supplements on him. Which jogger experienced less dizziness? Hint: Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body.

[Q]: The country of Qatar is opulent, to say the least. They have one of the highest per capita income in the world - exceeding that of Western Europe and North America. Over-consumption is the way of life in Qatar. While similarly small country of Bhutan puts emphasis on the happiness of its citizens in a different way. Bhutan does not give way to material over-consumption like Qatar does - it cares about its citizens' spiritual and social well-being. Would Bhutan most likely lose or retain its resource bases? Hint: Overconsumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. A prolonged pattern of overconsumption leads to environmental degradation and the eventual loss of resource bases.

[Q]: Mark was studying the effect of Sun's radiations on Earth. To that end, he studied Sun's radiations, which he labeled as rad A. Then he studied Earth's radiations, which he labeled as rad B. He also learned that longer wavelength radiations would produce heat. Would rad A have longer or shorter wavelengths than rad B? Hint: Solar radiation (or sunlight) is the energy Earth receives from the Sun. Earth also emits radiation back into space, but at longer wavelengths that we cannot see. Part of the incoming and emitted radiation is absorbed or reflected by the atmosphere. In May 2017, glints of light, seen as twinkling from an orbiting satellite a million miles away, were found to be reflected light from ice crystals in the atmosphere.
