Please answer this: I can use this background: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. Now, I have a new situation: The ecologist moved from Aspen, where there was no air pollution, to Seattle which experienced a lot of air pollution. He started studying the weather there as well. Answer this question please: Which city had rain with a higher pH?
++++++++
Answer: Aspen

Please answer this: I can use this background: In a bakery, angel food cakes could be baked in a rack oven, revolving oven, convention oven, or small deck oven. A commercial bakery may use a tunnel or traveling oven.[7] When the cake has finished baking, it should have a golden brown color on the exposed area.[5] The final volume will generally be two to three times larger than the batter volume.[6] Now, I have a new situation: Two bakeries were famous in town for their angel food cakes. Tom's was a small bakery with various small ovens, took small orders and did some catering. Bill's bakery was large and produced angel food cake commercially, in vast quantities. Answer this question please: Which bakery didn't use a revolving oven to bake angel food cakes?
++++++++
Answer: Bill's

Please answer this: I can use this background: 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. Now, I have 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. Answer this question please: Which brother had a specific mutation in the primary sequence of his hemoglobin molecules?
++++++++
Answer:
Mike
