Please answer this: I read this background article the other day: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. I am facing a new situation today: Trisha has a doctors appointment to get some blood work done. She goes to see her doctor and he takes a blood sample. Sadly when he comes back he reports to her that her blood cells are misshapen and look like small sickles, as well as her hemoglobin is being produced incorrectly. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will a person with sickle cell anemia have circular red blood cells or red blood cells shaped like sickles?

Answer: sickles
Problem: I read this background article the other day: Shad are also valued as a sport fish that exhibit complex and little-understood feeding behavior while spawning. Unlike salmon, shad retain the ability to digest and assimilate food during the anadromous migration. Like other fish, their feeding instinct can be triggered by a variety of factors such as turbidity and water temperature. Anglers use both spinning and fly fishing tackle to pursue shad. Spin fisherman use a shad dartjig or a flutter spoon. Some anglers use a downrigger to place the artificial lure at the desired depth and location. This is usually in the channel, or deepest part of the river. Migrating shad tend to occupy the lower portion of the water column which makes this the typical depth of choice for fishing. In the North, April through June is when shad spawn in coastal rivers and estuaries once water temperatures have reached 58 degrees Fahrenheit (14 C). Fishing conditions typically improve as water temperatures warm and flow decreases. I am facing a new situation today: Jeff loves to go shad fishing. He prefers using fly fishing tackle and is planning a fishing trip up North with his buddies. They decided to take their trip in May when everyone can get off work over the Memorial Day holiday. Sam enjoys shad fishing as well, but the only time he and his buddies are able to take off work is during their slow season in March. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who will have better fishing conditions and likely catch more shad on their fishing trip, Jeff or Sam?

A: Jeff
Problem: Given the question: I read this background article the other day: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3) and phosphates (PO4) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally). I am facing a new situation today: Two neighboring dairy farms produced milk for half the state. Berry farm produced conventional milk, while Rose farm produced organic milk. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm had milk production which reduced pesticides utilization?
++++++++++++++++++++++++++++++++
The answer is:
Rose
input question: I read this background article the other day: One reason radiation is dangerous is that it can't be detected with the senses. You normally can't see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. I am facing a new situation today: Tom and Jacob are carrying Geiger counters through an old abandoned city near a nuclear plant. Tom walks into a hotel and looks around at all the paintings and old couches in the lobby. His Geiger counter remains silent, but as he walks up the stairs toward the second floor it starts to slowly but steadily make more sound. Jacob steps into a grocery store when his Geiger counter immediately starts making lots of noise, but his device starts to drop off in sound as he walks toward the freezer in the back of the store. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is currently detecting less radiation????
output answer: Tom
I read this background article the other day: 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. I am facing a new situation today: Hydrologists studied two samples of rain water. Jim studied an acid rain sample from a nearby city, and Dan studied a sample of water from another town. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which hydrologist learned more about air pollution?

Answer: Jim
Q: I read this background article the other day: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. I am facing a new situation today: Dan is conducting a research to see how a substance behaves in varying pressure. First, he selects a gaseous substance in very low pressure. He calls it as case A. Then he increases the pressure. He calls it case B. Finally, he increases the pressure even further. He calls it case C. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which case would see less distance between particles, case B or case C?
A:
case C
