[Q]: You are given a new situation: Barb and Ann were friends. The used to play together outside in the yard till one day Barb's parents found out that she had sickle cell anemia. They haven't played together since. 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 of the girls didn't have a life threatening disease?
****
[A]: Ann

[Q]: You are given a new situation: Ian is learning about alkanes in science class and their melting and boiling points. He is given a few different alkanes try try with this test, mainly methane ethane and a third alkane that he has to test to find out what it is called Alkane C. and a hint : Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. Please answer this question : Given Alkane C has more carbon atoms than ethane, which will have a higher boiling/melting point, ethane or Alkane C?
****
[A]: Alkane C

[Q]: You are given a new situation: Boone county experienced severe weather last week as a result of atmospheric convection. White county to the east experienced some rain but was sheltered from this phenomenon because of the mountain range. and a hint : Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Please answer this question : Which county experienced more different lapse rates within dry and moist air masses?
****
[A]: Boone

[Q]: You are given a new situation: Two friends met after 20 years. Tom had been smoking tobacco all these years and had some health problems related to that, while Randy quit smoking 25 years ago. and a hint : Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel. Please answer this question : Which friend had a lower risk of developing cancer of the throat?

[A]:
Randy
