Biology Key Questions Essay - 675 Words

Biology Key Questions – Lesson #1 1. How many electrons does Mg2+ have? Answer: Mg2+ has 10 electrons. A Magnesium atom has 12 electrons, 2 of which are valence electrons. The atom will lose the 2 outermost electrons in order to stabilize its electron shell. The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years, how useful do you think this isotope would be for dating bones that are over a million years old? Answer: Carbon-14 is incorporated in the tissues of plants and animals through their environment. When they die the incorporation of carbon-14 ends, and what remains in the specimen decays at a constant rate, with a half-life of†¦show more content†¦When the two smaller reactants join together, water is produced and removed during the synthesis of the larger molecule. This is also called Dehydration Synthesis. For example, molecules with projecting Hydrogen atoms bond with molecules with projecting Hydroxyl groups (-OH), forming water. The water molecule then leaves the reactants, allowing them to bond to form a larger, more complex molecule. This type of reaction occurs continuously throughout the body in the joining of amino acids to form protein. Amino acid + Amino acid ïÆ'   Protein + Water Oxidation and Reduction (Redox) A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge. *Zn(s) + Cu2+ ïÆ'   Cu(s) + Zn2+(aq) Cellular respiration is a redox reaction that combines glucose oxygen to produce carbon dioxide, water, and energy. Neutralization: Neutralization reactions are those that involve the reaction of an acid and a base to form water and salt. A solution with a high hydrogen ion concentration is acidic, and a solution with a high concentration of hydroxide ions isShow MoreRelatedUnit 1 Lesson 1 Key Question Biology SBI4U Essay1283 Words   |  6 Pagesï » ¿Unit 1 Lesson 1 Key Question Biology SBI4U-C ILC 1) Mg2+ Has 10 electrons. 2) Carbon -14 would not be effective at dating bones that are millions of years old.

Themes of Failure, Self Delusion, and Conflict in Death...

Throughout the play â€Å"Death of a Salesman† there are multiple themes, some are obvious and others are just noticeable. Much of it revolves around the Main Character Willy and how he has confused reality with constant illusions and dreams. Based on my experience with â€Å"Death of a Salesman† I can say that there are multiple themes fused through this play. For example the author used these themes to create a strong central meaning or message that the reader can clearly understand. Overall I believe Arthur Miller has delivered conflict, self-delusion and failure to be the root of the many themes included in his book. Conflict is detected much around Willy’s character and everything that revolves around him. On one hand he is constantly†¦show more content†¦According to Biff Loman, his entire life has been a joke. â€Å"I realize what a ridiculous lie my whole life has been! We’ve been talking in a dream for 15 years.† (Death of a Salesm an 81) However Biff realizes that his father and his own dreams were nothing but dreams and illusions. The self-delusion of Biff shows that he has been living in a dream world along with his father, Willy. The Author fixes the mood on pity and sympathy towards Biff and Willy. Self Delusion is strongly backed up by the moods of characters throughout the play as dreams and mere illusions about the average American life. I believe failure is the largest and yet most obvious theme in the story â€Å"Death of a Salesman.† After Willy’s death, during his funeral Biff said â€Å"He had all the wrong dreams. All, all, wrong. He never knew who he was.† (Death of a Salesman 111) Willy accomplished nothing, he felt as if there was nothing he could leave behind for his children and wife. â€Å"I’ve got to get some seeds, right away. Nothing’s planted. I don’t have a thing in the ground.† (Death of a Salesman 96) His entire life was nothing but dr eams and illusions and when it finally came down to the point where those lies had to stop, he knew he had nothing at all. In conclusion failure is expressed in common ways that we are all familiar with, this way the Author can reach his audience clearly and vividly.

Richard Wrights Novel, Native Son, Stirred Up A Real Controversy By Sh

Richard Wright's novel, Native Son, stirred up a real controversy by shocking the sensibilities of both black and white America. The protagonist, Bigger Thomas, is from the lowest ring of society, and Wright does not blend him with any of the romantic elements common to literary heroes. Bigger is what one expects him to be because of the social conditions in which he lives: he is sullen, frightened, violent, hateful, and resentful. He is the product of the condemnation the "white" society has brought upon him. He is a "native son." Native Son opens with an act of violence. The alarm clock abruptly awakens Bigger and his family to their miserable reality--a rat-infested, one bedroom apartment in the urban ghetto of Chicago. Bigger's battle with the rat reveals his capacity for brutality. He crushes the rat's head after he has killed it with a skillet. Bigger represents a persuasive racial stereotype of black men--violent, criminal, and cowardly. The powerful, racist white majority considers his personality a natural characteristic of his race. However, Wright shows how Bigger's consciousness is in fact shaped by his environment. Bigger was not born a violent criminal, but became one in the unforgiving world of racism and poverty in American society. Bigger's entire existence is a prison. His crowded, rat-infested apartment is only one of his prison cells. He is imprisoned in the urban ghetto by racist rental policies. His own consciousness is a prison. His entire life is filled by a sense of failure, inadequacy, and most importantly, unyielding fear. Racist white society, his mother, and even Bigger himself all believe that he is destined to meet a bad end. His relentless conviction of an impending awful fate demonstrates that Bigger feels a nearly complete lack of control over his life. He is permitted access only to menial jobs, substandard housing, substandard food. Basically, white society permits him no choice but a substandard life. Gus and Bigger play-act at being white. They alternately play at being a general, J.P. Morgan and President. Gus and Bigger act out a skit in which the President wants to keep the niggers under control. They associate whiteness with the power, wealth, and authority to deny them control over their own lives. Bigger hates and fears whiteness. Therefore, he has a latent desire to do violence to the force that oppresses him. Backed into a corner, he is primed to lash out at the very force that restrains him through fear. Buckley's campaign poster states the message that Bigger believes is written all over his very existence: You Can't Win. His poster foreshadows Bigger's inevitable, losing confrontation with white authority. Bigger is alienated in the most profound sense. He is alienated from the middle-class comforts of white society, alienated from his family, his friends, and ultimately, himself by his overwhelming sense of impotent shame and frustration. He cannot bear to feel the full range of his rage and misery, so he resorts to self-deception. The hopelessness of this social reality threatens to utterly destroy him. Bigger has no solidarity with his family, because their misery only accentuates his helplessness to alleviate it. He has no solidarity with his friends. His fear and theirs perpetually keep their relations full of tension and barely suppressed anger. He has no sense of solidarity based on race except the same companionship based on misery that he has with his family. He even robs other black people--who are almost certainly poor as well--because he is too afraid to break a dangerous social taboo by robbing a white man. Racism has conditioned not only Bigger's relationship with white, but his relationship with other members of his race as well. Wright wants to show that, considering the conditions of Bigger's existence, his violent personality and his criminal behavior are not surprising. Bigger wants to feel like a human being with a free, independent will. Crime is one avenue to obtain money without submitting to white authority by taking the menial jobs assigned to him. His overwhelming sense of fear arises from his feeling of impotence in the face of an unnamed, impending doom. Crime is an act of rebellion, an affirmation of his independent will to act against the voice of social authority.
