Behavioral Genetics How Does Genes Influence Brains...

Behavioral Genetics: How does Genes Influence Ones Behavior Many believe that the environment such as the individuals people associate with, the extracurricular activities people are involved in, the music people listen to, including things shown on tv and video games all influence behavior. Though all of the things listed above are said to be true, and do indeed play a role in behavior. There are major things inside the body that trigger peoples behavioral responses. Those major things are called genes. This paper will include a breakdown of genetics and behavior alone, including the definitions of each to allow a better understanding of the joint term â€Å"behavioral genetics†. Some very important biological and chemical concepts about the body that will help to understand where genes come from will be introduced. As well as a brief example of how the environment and genes come together to influence what we do. The type of genes that influence behavior, along with the influence behavioral genetics has on the brain will also be discussed. Genetics What are genetics? Genetics is the study of heredity, which is a biological process where certain traits are getting passed from parent to offspring or child (â€Å"What is Genetics†). All of our genetic DNA lies within the nucleus of all living cells in a persons body. The DNA found in the cells make the human genome. â€Å"There are about 20,000 genes located in one of the twenty three chromosomes found inside the nucleus (â€Å"What isShow MoreRelatedPerspectives of Psychology1141 Words   |  5 Pagesof mental processes, couple with behaviors, and experiences (Kalat, 2011). There are many ways in examining, mental processes and behaviors among people, and therefore psychologist uses different perspectives to understand how human beings, think, act, and behave. Some psychologist uses one perspective to analyze behaviors, and other uses a multidimensional approach.

Plato s Meno As A Socratic Discussion On Human Sexuality...

Plato s Meno is a Socratic discussion on the definition of human virtues where the main participants are Socrates and Meno. Other speakers in the dialogue include an Athenian politician, one of Meno s slaves, and Socrates’ prosecutor Anytus, who is a friend to Meno. Meno wants to understand the broad definition of human virtues and while visiting Athens he initiates the dialogue on virtues with Socrates. The discussion begins with Meno inquiring from Socrates whether virtues can be learned. Meno argues that, according to the Georgian’s, the attribute is defined differently by different people, and there is no common way to define it so as to apply it to all human beings. In response, Socrates argues that the Georgians do not understand the real meaning of virtue and in his opinion that some attributes are common to all human beings. Socrates also rejects the idea that virtues depend on human sexuality and age and insist that there are common attributes in humans. The conversation between the two becomes an argument on about the perfect definition of human characteristics. In essence, this paper discusses the critics in Plato s Meno that led to a senseless conclusion on virtues as it was significantly contributed by Socrates. As well, the paper will support the argument that the agreement between Socrates and Memo was based on distinct ideas. A misunderstanding starts when extracting virtues from the human characters. Meno, defines quite a number of human virtues, but

Analysis of Oxygen Bearing Compunds Free Essays

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1 ° (primary), 2 ° (secondary), 3 ° (tertiary) alcohols. Tests such as the dichromate test, Tollen’s test, Lucas test, DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment, the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result was that it was a primary alcohol. We will write a custom essay sample on Analysis of Oxygen Bearing Compunds or any similar topic only for you Order Now It went through the Dichromate reaction, Tollen’s reaction and finally the Lucas reaction. Introduction â€Å"The analysis of oxygen bearing organic compounds† is an experiment in which a variety of tests are available to identify a compound’s property whether it is a primary, secondary or tertiary alcohol. The tests that are included to come up with such results are interconnected with one another like that of the Dichromate test, followed by the Tollen’s test to yield an aldehyde if positive for mirror coating. The second set of procedure would again start with The Dichromate test, followed by the Tollen’s test and finally the Lucas test to yield either primary alcohol if it became turbid or secondary alcohols as it’s result if it did not turn turbid. The last set of interconnected tests were that of again, the Dichromate test, Followed by the DNPH that would determine if the unknown sample is a Ketone (positive for red-orange precipitate) or a tertiary alcohol (if negative for red-orange precipitate). But before going deeper on what these tests are, what first are the difference between their results which are the primary, secondary and the tertiary alcohols, aldehydes and ketones? Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Note however that there are different kinds of alcohols and Alcohols are categorized into different classes depending on how the -OH group is positioned and arranged on the chain of the carbon atoms. Chemical differences between the various types are possible. First to be discussed would be the Primary (1 °) alcohol, in which the carbon carrying the -OH group is only attached to one alkyl group. Meanwhile, In a secondary (2 °) alcohol, the carbon with the -OH group attached is joined precisely to two alkyl groups, these alkyl groups that are attached to the carbon chain may be the same or different. In a tertiary (3 °) alcohol, the carbon atom holding the -OH group is attached directly to three alkyl groups, which may be any combination of same or different [1]. On the other hand, another result that can occur would be the presence of ketones and Aldehydes. But again, to understand the experiment further, what are Ketones and aldehydes? A ketone can be characterized as either the functional group categorized by a carbonyl group (O=C) attached to two other carbon atoms or it can be identified as a chemical compound that contains a carbonyl group. A carbonyl carbon bonded to two carbon atoms makes ketones different from carboxylic acids, aldehydes, esters, amides, and other oxygen-containing compounds. The double-bond of the carbonyl group distinguishes ketones from alcohols and ethers. The simplest ketone known is acetone [2]. Lastly among the results is the aldehyde. The term aldehyde seems to have arisen from the wordds alcohol dehydrogenated. Way back in earlier times, aldehydes were at times named after the corresponding alcohols, for example, vinous aldehyde for acetaldehyde. (Vinous is from Latin vinum = wine, the traditional source of ethanol; compare vinyl. ). An aldehyde is an example of an organic compound which has a terminal carbonyl group. This functional group, which consists of a carbon atom bonded to a hydrogen atom and double-bonded to an oxygen atom (chemical formula O=CH-), is commonly called the aldehyde group. The other names for aldehyde group are formyl and methanoyl group. The aldehyde group is considered polar. Oxygen, which is more electronegative than carbon, pulls the electrons in the carbon-oxygen bond in the direction of itself, creating an electron deficiency at the carbon atom. Owing to resonance stabilization of the conjugate base, an ? -hydrogen in an aldehyde is more acidic than a hydrogen atom in an alkane, with a typical pKa of 17 [3]. Results and discussions The experiment included parallel testing of 3 liquids that would be used for comparison. the first sample would be the unknown sample, the second would be the positive standard in which formaldehyde was used and the last wold be the negative sample in which the simplest ketone, Acetone was used. Only three test were used to determine whether the group’s unknown sample was under the category of primary, secondary, tertiary alcohol, aldehydes or ketones. The three tests were done one after the other in this order: Dichromate test, Tollen’s test, and Lucas test respectively. In the Dichromate test, the unknown sample and the formaldehyde turned green meaning that dichromate oxidized the primary alcohol, secondary alcohol, and aldehydes to ketones or carboxylic acids. Samples turning green would be an indicator that the samples are positive for oxidation and therefore are oxidizable. On the other hand, the acetone remained orange which means that it is not oxidizable and can be further continued to another test, the DPNH test which would prove that it is categorized as a ketone because of the presence of a red-orange precipitate that indicates that the DPNH reagent condenses with the carbonyl containing molecules. The second test that followed the Dichromate test was the Tollen’s test. In this test, the unknown sample turned clear gray and the formaldehyde turned into a dark grey liquid with silver streaks. The silver streaks are similar with the silver mirror coat that means that the Tollen’s reagent oxidized the ammonium salts of the carboxylic acids with this, the formaldehyde was categorized as an aldehyde. Alternatively, The clear grey liquid of the unknown sample would indicate that it was not positive for the Tollen’s test and therefore it would need to continue to be tested so as to decipher if it is a primary or secondary alcohol. The last test would be the Lucas test in which the unknown sample did not turn turbid and therefore it was concluded to be a primary alcohol. Together with the unknown sample that did not turn turbid was isopropyl and MeOH which just remained as clear liquids. then again, the sample liquid that turned turbid was the tertbutyl. By this reaction, it is said that alcohols are converted to alkyl chlorides with ZnCl2 taking into consideration too that different alcohol types respond at different rates with ZnCl2. Table 1.

An unknown sample was given and it should be parallel tested with two other standards- one would be positive and one would be negative. B. The Dichromate test started the experiment. 8 drops of the unknown sample as well as the the two other standard- formaldehyde and Acetone was placed in separate test tubes addind 2 drops of of 10% K2Cr2O7 and 5 drops of 6M H2SO4. C. The Tollen’s test followed. 2 ml of freshly made Tollen’s reagent and 5 droops of the unknown sample were mixed. After 5 minutes and the silver precipitate did not form yet, it was placed in a 70 degree water bath for another 5 minutes. Then the results were observed. D. The last test was the Lucas test in which the iunknown sample, tertbutyl, isopropyl and MeOH was tested all at the same time. 5 drops of the sample was and 15 drops of concentrated HCl was mixed together with a â€Å"corn grain† amount of ZnCl2 solid and the appearance of turbidity was observed or not. Conclusion: It can be concluded that the unknown sample that was given to be tested was an oxidizable, primary alcohol based on the tests that were conducted. Since it was positive for the dichromate test, it was deemed to be oxidizable. In the Tolle’s test, as it did not produce a mirror coat, it was directed to the choice of being a primary or a secondary alcohol. And for the last test, the Lucas test, it was finally concluded that it was a primary alcohol since it did not turn turbid.
