Q: Context: Do you know what your blood type is? Maybe you have heard people say that they have type A or type O blood. Blood type is a way to describe the type of antigens, or proteins, on the surface of red blood cells (RBCs). There are four blood types; A, B, AB, and O. 1. Type A blood has type A antigens on the RBCs in the blood. 2. Type AB blood has A and B antigens on the RBCs. 3. Type B has B antigens on the RBCs. 4. Type O does not have either A or B antigens. The ABO blood group system is important if a person needs a blood transfusion. A blood transfusion is the process of putting blood or blood products from one person into the circulatory system of another person. The blood type of the recipient needs to be carefully matched to the blood type of the donor. Thats because different blood types have different types of antibodies, or proteins, released by the blood cells. Antibodies attack strange substances in the body. This is a normal part of your immune response, which is your defense against disease. For example, imagine a person with type O blood was given type A blood. First, what type of antibodies do people with type O blood produce? They produce anti-A and anti-B antibodies. This means, if a person with type O blood received type A blood, the anti-A antibodies in the persons blood would attack the A antigens on the RBCs in the donor blood ( Figure 1.1). The antibodies would cause the RBCs to clump together, and the clumps could block a blood vessel. This clumping of blood cells could cause death. A person with type O blood has A and B antibodies in his/her plasma; if the person was to get type A blood instead of type O, his/her A antibodies would attach to the antigens on the RBCs and cause them to clump together. People with type A blood produce anti-B antibodies, and people with type B blood produce anti-A antibodies. People with type AB blood do not produce either antibody. The second most important blood group system in human blood is the Rhesus (Rh) factor. A person either has, or does not have, the Rh antigen on the surface of their RBCs. If they do have it, then the person is positive. If the person does not have the antigen, they are considered negative. Recall that people with type O blood do not have any antigens on their RBCs. As a result, type O blood can be given to people with blood types A, B, or AB. If there are no antigens on the RBCs, there cannot be an antibody reaction in the blood. People with type O blood are often called universal donors. The blood plasma of AB blood does not contain any anti-A or anti-B antibodies. People with type AB blood can receive any ABO blood type. People with type AB blood are called universal recipients because they can receive any blood type. The antigens and antibodies that define blood type are listed as follows ( Table 1.1). Blood Type Antigen Type Plasma Antibodies A B AB O A B A and B none anti-B anti-A none anti-A, anti-B Can Receive Blood from Types A,O B,O AB, A, B, O O Can Donate Blood to Types A, AB B, AB AB AB, A, B, O 
 Question: a person with blood type a can receive blood from

A: a and o.

Q: Context: Sedimentary rocks follow certain rules. 1. Sedimentary rocks are formed with the oldest layers on the bottom and the youngest on top. 2. Sediments are deposited horizontally, so sedimentary rock layers are originally horizontal, as are some vol- canic rocks, such as ash falls. 3. Sedimentary rock layers that are not horizontal are deformed. Since sedimentary rocks follow these rules, they are useful for seeing the effects of stress on rocks. Sedimentary rocks that are not horizontal must have been deformed. You can trace the deformation a rock has experienced by seeing how it differs from its original horizontal, oldest- on-bottom position. This deformation produces geologic structures such as folds, joints, and faults that are caused by stresses. Youre standing in the Grand Canyon and you see rocks like those in the Figure 1.1. Using the rules listed above, try to figure out the geologic history of the geologic column. The Grand Canyon is full mostly of sedimentary rocks, which are important for deciphering the geologic history of a region. In the Grand Canyon, the rock layers are exposed like a layer cake. Each layer is made of sediments that were deposited in a particular environment - perhaps a lake bed, shallow offshore region, or a sand dune. (a) The rocks of the Grand Canyon are like a layer cake. (b) A geologic column showing the rocks of the Grand Canyon. In this geologic column of the Grand Canyon, the sedimentary rocks of groups 3 through 6 are still horizontal. Group 2 rocks have been tilted. Group 1 rocks are not sedimentary. The oldest layers are on the bottom and youngest are on the top. The ways geologists figure out the geological history of an area will be explored more in the chapter Earth History. Click image to the left or use the URL below. URL: 
 Question: the classic location to see layer cake geology is

Q: Context: The movie opens with spoofing "Armageddon" and "10,000 B.C." In the year 10,001 B.C., a caveman Will (Matt Lanter) runs away from a mammoth before getting in a fight with Wolf (Ike Barinholtz). He then encounters a saber-toothed, gasoline-drinking Amy Winehouse (Nicole Parker), who informs him that the world will end on August 29, 2008 (which was the film's opening day and Michael Jackson's 50th birthday), revealing their fate laying in a crystal skull "Indiana Jones". The film flash-forwards to the present, where Will apparently dreamed all of this. He then finds out that his girlfriend, Amy (Vanessa Minnillo), is having an affair with Flavor Flav (Abe Spigner) and the two break up with Will not admitting his true feelings for her.Later that day, Will has a "Sweet Sixteen" party at his house, despite the fact that he's 25. Among the guests are Juney (Crista Flanagan) spoof of "Juno" and Will's best friend Calvin (Gary "G-Thang" Johnson), who attempts to curve a bullet around the room "Wanted" to stop Seth and McLover "Superbad" (Noah Harpster and Austin Scott) from stealing the alcohol, accidentally killing "Dr. Phil" (John Di Domenico), Anton Chigurh (Barinholtz), and the Beautiful Assassin (Carmen Electra) in the process. By then, Amy arrives with her new boyfriend, an underwear model (Nick Steele), before the "High School Musical" number is performed with cameos by an off-key Jessica Simpson (Parker) and Justin Timberlake (Jonas Neal).However, the party comes to a halt when the lights go out as the room shakes and a bulletin on the radio claims that it is the end of the world. Will, Juney, Calvin and his girlfriend Lisa (Kim Kardashian) go outside during a meteor shower and find that "Hannah Montana" (Flanagan) has been crushed by a meteor and, even when caught between life and death, is still promoting her merchandise until her wig falls off, revealing her as Miley Cyrus before she finally dies. While this occurred, a kid (Ty Wesley) wakes up "Hancock" (Walter Harris) and mouths at him to go save the world, only to be knocked away as Hancock tries to flee the city but hits his head on a streetlight and knocks himself out. Soon after, the city starts to freeze over, and the group retreats to a garage for shelter. They meet the "Sex and the City" girls, who claim to have first grabs and Juney beats a drag queen version of Carrie Bradshaw (Jason Boegh) for the garage "Don't Mess With The Zohan". After discussing global warming, Calvin says that he is cold and suggests they take their clothes off. Only the girls take their clothes off, and the guys stare in awe until Juney's water broke.Later, Will has a dream where he is a "Jumper" and accidentally impales himself on Prince Caspian's (Barinholtz) sword (Caspian identifies him as "the guy who ruined Star Wars"; also a reference to Matt Lanter's voice role as Anakin Skywalker in the 2008 CGI Clone Wars television series). After Will's dream ended and he was chided for not even trying to commit to his relationship, the gang leaves the garage and Will gets a call from Amy, admitting his feelings for her before he decides to get to her as Lisa gets killed by a meteor. While the others comfort a distraught Calvin, the "Enchanted" Princess climbs out of a manhole and gets hit by a taxi, with Calvin catching her as they immediately fall in love with each other. Juney guesses she's a princess thrown out of her kingdom by an evil witch, the Princess explains that she's a "demented homeless chick who lives in the sewers" due to consuming "lots and lots and lots of mind-altering, enchanting drugs!" After getting into a dance off with the Princess's Princely pimp dancing to Sizzle C's 'I Like 
 Question: Who is Amy having an affair with?
