Question: John is learning more about different cultures and people around the world. He noticed that people have different skin colors. To learn more about the science behind skin colors he categorized the skin colors into two broad groups, case D and case L. Case D is represented by darker skin and case L is represented by lighter skin. Would case L produce more or less melanin than case D? Hint: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency.
Answer: less

[Q]: Rob is a chemist with a pharmaceutical company. He is trying to devise a technique that would be able to control chemical reactions. For that, he conducted two tests. In the first test, he used warmer reactants. He called it reactant A. In the second test, he used cooler reactants. He called it reactant B. Would particles would collide with smaller or greater force in reactant A than in reactant B? 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.

input: Please answer the following: Greg is an electrical engineer. He works for an engineering firm that builds houses. Yesterday, Greg was checking two of the houses. He noticed that one of the houses had short circuit. He labeled that as case A. But the other house didn't have short circuit. He labeled that as case B. In which case the incoming and outgoing current wires would not touch each other, case A or case B? Hint: In the wiring of a building, the wires carrying the current in and out are different and never touch directly. The charge passing through the circuit always passes through an appliance (which acts as a resistor) or through another resistor, which limits the amount of current that can flow through a circuit. Appliances are designed to keep current at a relatively low level for safety purposes. The appropriate voltage and resistance in a circuit keeps the current in control and keeps the circuit safe. It is possible, however, for something to happen that causes the wire bringing the current in to come into contact with either the wire carrying the current out or the ground wire, thus causing what is called a short circuit . In a short circuit, some or all of the resistance is cut out of the circuit allowing the voltage to push a huge current through the wires.

Please answer this: In the ant world a war has been waged. Two rival groups of Acromyrmex heyeri ants, group A and group B, are battling each other to gain territory. The goal is to attack the rival group when they have more openings in their nest thatch. In battle day one group A territory had 5 C temperature. In battle day two group A territory had 22 C temperature. In battle day three group A territory had low air humidity. In battle day four group A territory had high air humidity. In which battle day group A would have more openings in their nest thatch, battle day three or battle day four? Hint: Acromyrmex heyeri is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Acromyrmex. Acromyrmex heyeri workers construct the colonies nest by thatching together cut grass. At temperatures ranging from 2030 C, workers created more openings in the nest thatch as the internal nest temperature goes up as a method of temperature regulation for the colony. The workers will close openings in the nest thatch as the air humidity surrounding the nest decreases to reduce water loss for the colony.

Problem: Anthony is going in for a doctors appointment. He hasn't been feeling well and has been vomiting. When he talks to his doctor the doctor can tell immediately what's wrong. Anthony's physical appearance immediately tells the doctor that he likely has hepatitis B. Given a person's eyes and skin tone appear to be yellow and they experience vomiting, will the chances that they have hepatitis B increase or decrease? Hint: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B.

input: Please answer the following: The Madrigal Ocean and the Listy Ocean are two bodies of water currently under observation by scientists on a planet nearly identical to Earth. Although the studies have just started, the scientists have already discovered that the salinity of the Madrigal Ocean is much lower than that of the Listy Ocean. This isn't much information, but it's progress and the scientists are not going to stop their studies until they learn all that they can about these waters. Which ocean is more likely to have lower evaporation? Hint: Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years.
