Please answer this: You are given a new situation: Pete and Mike were two brothers. Pete had no health problems, while Mike inherited the sickle cell trait. Mike had adjacent health problems. and a hint : Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition. Please answer this question : Which brother had some hemoglobin S in his blood?
++++++++
Answer: Mike

Please answer this: You are given a new situation: People from two villages ate lots of salt. People from Salt village used regular salt, while people from Sand village people used iodized salt in their diets, after talking to specialists. and a hint : Before iodized salt was developed, some people experienced a number of developmental difficulties, including problems with thyroid gland function and mental retardation. In the 1920s, we learned that these conditions could usually be treated easily with the addition of iodide anion to the diet. One easy way to increase iodide intake was to add the anion to table salt. This simple step greatly enhanced health and development. Large amounts of iodide ion are also found in seaweed such as kelp (see picture above) and saltwater fish. Please answer this question : Which village had fewer people with enhanced health?

Answer: Salt

Please answer this: You are given a new situation: Helen is working in the kitchen when she goes to the freezer to get some ice cubes. There is only one ice cube left so she takes it out and sets it in the glass on the table. She then refills the ice cube tray with water and sticks it back in the freezer. and a hint : Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C. Please answer this question : Is the density of the water increasing or decreasing?
++++++++
Answer:
increasing
