Document A: Eugene V. Debs Speech (Modified) Eugene V. Debs was a founding member of the Industrial Workers of the World (IWW), U.S. presidential candidate of the Socialist Party of America, and one of the most famous American socialists. This excerpt is from a speech he gave across the street from a jail, where he had just visited three socialists who were in prison for opposing the draft. Comrades, friends and fellow-workers, . . . three of our most loyal comrades are paying the penalty for their devotion to the cause of the working class. They have come to realize, as many of us have, that it is extremely dangerous to exercise the constitutional right of free speech in a country fighting to make democracy safe in the world. . . . Every one of the aristocratic conspirators and would-be murderers claims to be an arch-patriot; every one of them insists that the war is being waged to make the world safe for democracy. What humbug! What rot! What false pretense! These . . . tyrants, these red-handed robbers and murderers, [say they're] the "patriots," while the men who have the courage to stand face to face with them, speak the truth, and fight for their exploited victims-they are [called] the disloyalists and traitors. If this be true, I want to take my place side by side with the traitors in this fight. . . . [He] who owns the earth and tells you that we are fighting this war to make the world safe for democracy-he who profiteers at the expense of the people who have been slain and mutilated by the thousands, under pretense of being the great American patriot... is in fact the archenemy of the people; it is he that you need to wipe from power. It is he who is a far greater menace to your liberty and your well-being than the... [Germans] on the other side of the Atlantic Ocean.

Individuals with sickle cell anemia are homozygous for the gene Hbs, which specifies an altered hemoglobin molecule. The red blood cells of afflicted individuals become sickle shaped when deoxygenated, impeding blood flow and lysing. The allele Hbs is codominant with the allele Hb" for normal hemoglobin, i.e. in the heterozygous individual both normal and altered hemoglobin are produced. Under everyday circumstances heterozygous individuals are outwardly phenotypically indistinguishable from individuals homozygous for normal hemoglobin. A husband and wife phenotypically normal had a son with sickle cell anemia. a What are the genotypes of the husband and wife? b What is the probability that the couple's second child would have sickle cell anemia?

A man walked into Smallville Apartments and burglarized several units. When the Smallville crime scene investigators arrived, they found two fingerprints on the counter in one of the units that they believed were left by the perpetrator. The first fingerprint was classified as a loop and the second fingerprint was classified as a whorl. The investigators went back to the police station and looked through their fingerprint cards until they found a local man with a record of driving while under the influence of alcohol who had both loop and whorl fingerprint patterns on the same hand. They arrested the man confident they had found the perpetrator. 1) Why are they wrong to be confident in their arrest and what errors in investigating fingerprints did they make? You should discuss at least three reasons the investigators are incorrect in this situation. 2) What type of prints were collected from the kitchen counter, patent, plastic, or latent? Construct an explanation for what technique could be used to lift and evaluate these prints.

How do Scientists think our sun was created, or born? Other life forms constructed gravitational hydrogen atoms that pulled together to create the sun. The force of gravity pulled more and more material into the center of this swirling disk. Eventually, the pressure in the center was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy. The sun was genetically constructed in a laboratory and released into the atmosphere and allowed to continue it's nuclear fission until it was large enough to be a sun. Scientists have never investigated the sun.
