Problem: Given the question: You are given a new 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. and a hint : 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. Please answer this question : In which person's reaction will the acid and base particles move faster?
++++++++++++++++++++++++++++++++
The answer is:
Justin

Problem: Given the question: You are given a new situation: Two plants of the same type are growing near the outskirts of the Jorah forest. The first plant, colored red, is healthy and has no fungus on it. The other plant, colored black, has a fungus growing on the roots of it. These plants have been around for centuries and if crushed into a powder actually make a nice seasoning to add to a meal. and a hint : A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Please answer this question : Does the black plant absorb more or less nutrients from the soil than the red plant?
++++++++++++++++++++++++++++++++
The answer is:
more

Problem: Given the question: You are given a new situation: Jason and Barbara went out swimming at the beach while on vacation. Before heading outside, Barbara put sunscreen on her body and then handed the bottle to Jason. Jason decided that it wasn't sunny enough out to warrant sunscreen and didn't put any on. and a hint : Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. Please answer this question : Who is less likely to get skin cancer?

The answer is:
Barbara
