Lab Report On Chemical Compounds - 1107 Words

Abstract: In this lab report two unknown substances will be tested. The tests performed were looking for the presence of the main biomolecules, Carbohydrates, Lipids, and Proteins. The tests used will be used in the Lab report are; The Benedicts test to test for sugars, the Iodine test for coiled or non-coiled carbs, The Grease-spot test for lipids, and the Biuret test for proteins. Tests show that both substances had different responses to the Benedicts test. Both substances shared the same response to the Iodine test. In the Grease-spot test both showed the same. In the Biuret test the unknown substances resulted differently from each other. Introduction/ Discussion: Discussed in Chapter 5 â€Å"The Composition of†¦show more content†¦Unsaturated fats include items such as olive oil and soybean oil. Saturated fats are fats that are become solid in room temperature; examples include lard, butter, and coconut oil. To test for lipids the grease-spot test can be implemented. In the grease-spot test it is to be observed if the spot is translucent, this indicates there are lipids. Proteins are components of tissue; proteins themselves are composed of amino acids which serve as building blocks. To test for proteins the Biuret test is used. Using a Biuret reagent the color of the solution will change depending on the presence of proteins. The solution will turn from blue to violet if proteins are indeed present. In this lab for testing the unknowns each test will be performed on unknown substances to test for the appearance of the four main molecules. These tests are important because they show the presence of these biomolecules which are in organisms. Materials and Methods: All materials and experiment steps were provided by the test from â€Å"Exploring Biology in the laboratory.† (Pendarvis. Carwley.) Two unknown solutions were tested. The first solution tested is B3. Using the Benedicts test the test tube was labeled at the 0.5cm mark and 1.0cm mark. The same thing was done with the A1 solution test tube.

Gender Roles Undermining The Female Gender - 1732 Words

Gender Roles: Undermining the Female Gender From birth, everyone was assigned a certain gender and are socialized to conform to certain gender roles based on their biological sex. Gender roles are standards created by society. Masculine roles are usually associated with dominance, strength, and aggression, while feminine roles are associated with nurturing, passivity, and subordination. This is where the term â€Å"gender inequality† becomes a major issue because to society men are supposedly the predominant gender, which then leads others to believe and treat women as the subsidiary sex. Women throughout history have endlessly worked to earn their rights, while men basically have everything offered to them. Recent laws have given women more freedom and rights, thus convincing people that gender roles are no longer a problem. Regardless of what society has convinced people, women still do not have equality because of gender roles. In this world, men have been seen as the superior sex and women have been considered the subordinate group. Clearly, gender roles have been set to support men. Women are not expected to have similar jobs or to have the physical strength men do, but instead they are expected to stay home, raise the kids, and take care of household needs. Men, being the strong ones, are the only ones required to have a job and do the heavy lifting. The current accepted views towards women’s roles create female inequality because women are being undermined just becauseShow MoreRelatedGender Feminism And Transgender Activism : A Scientific Disillusion974 Words   |  4 PagesGender Feminism and Transgender Activism: A Scientific Disillusion Debra W.

Retain Talent and Accelerate Performance †MyAssignmenthelp.com

Question: Discuss about the Retain Talent and Accelerate Performance. Answer: Introduction: In this paper a perspective on employee recognition and engagement is highlighted. The hypothesis tested in this chapter is that recognition is the only factor influencing engagement in employees all over the world. This is tested for different countries in this chapter (Gostick Elton, 2009). The results suggested that the factors influencing engagement were career opportunities, integrity and identification of employees with the organization. The chapter also describes in detail how each of these factors are important. The next chapter prescribes methods and factors that should be considered when calculating rewards for recognition (Gostick Elton, 2009). It helps to focus on the parameters that should be considered while rewarding so that the right impact is obtained out of the same. The tools prescribes are the award level, the award budget and creativity of awards for performance excellence. The next chapter suggests ideas to reward the employees. It provides a total of 125 ideas (Gostick and Elton, 2009). All these ideas are based on the suggestions of managers all over the world. The chapter also highlights how recognition can boost management capabilities by grouping the ideas into five categories which include interaction, objective setting, recognition, responsibility and trust.This is the concluding chapter of the book (Gostick Elton, 2009). It predicts how recognition propels results and target achievement in businesses. It asserts that essentially short term forces do not help firms to reach objectives in the long run. It claims that recognition of one success provides momentum for thousands of other such successes and leads to long term growth for firms in any part of the world. References: Gostick, A., Elton, C.

President Obamas famously i... free essay sample

President Obamas famously inspirational second inaugural speech delivered on the day of inauguration was given as a thanking speech combined by a declaration of needs to urge Americans to reclaim from conservatives the spirit of the founding fathers for equality among all. Americas first African American President who believed in democracy and believed in peace, justice, and most importantly equality. The speech shared much emotion, logic, and credibility by the leader of our country along with other rhetorical devices to enhance his speech.President Obama, in a close comparison on the day of his delivered speech, ties it to the speech spoken by Marin Luther Kings I Have A Dream alludes to establishing more ethos by reminding us (whom he is addressing) that equality is still of great importance to this very day as it was at the time it was written. Both in the importance of unity and structure of language, the president brings us to the past, telling us that freedom had a long line of being taken rather than given. We will write a custom essay sample on President Obamas famously i or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He uses logos to reinforce this idea by referring back to the American Revolution, which is reminding us, in a periodic sentence, that the patriots didnt fight for revenge, but for freedom. Freedom that we would keep safe passing it on to every single generation with it. Just as Martin Luther King had long before in his speech, President Obama springs us back into the present.He states off our countrys accomplishments, starting each achievement of society by together or we to express that it was a collective effort of many, giving the audience (everyone) a sense of pride and acknowledgement of the greatness and achievements that can come out of unity. President Obama begins next by starting his next paragraph with a rebuttal by beginning with But, bringing out a noticeable change of tone. Using deductive reasoning Obama more simply than previously words it out that the Nation cannot work under one individual, but work as a single unit as American people can no more meet the demands of todays world and No single person can train (what we need), Now, more than ever, we must do these things together, as one nation and one people. At this point, it creates a huge sense of unity and direction towards equality and togetherness. President Obama juxtaposes the ending of economic recovery which solidifies hope and of use parallelism we are made for this moment and we will seize it so long as we seize it together. He rallies again, a parallelism which is used frequently throughout the rest of the speech, we, the people, to drive further in establishing togetherness but also builds his presidential ethos, which is important to our freedom and our rights, while still a part of our nations unit as a whole.One of the most notorious parts of the Presidents speech was in support of gay rights. Obama, early in his first term, was heavily criticized by gay organizations for failing to do enough. So, he redeems himself, We, the people, declare today that the most evident of truths – that all of us are created equal – is the star that guides us still; just as it guided our forebears through Seneca Falls, and Selma, and Stonewall, here in the speech through support for gays in the military and for equal marriage rights, but he placed the battle for gay rights, alongside other key civil and womens rights fights. Also said, Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, and If we are truly created equal, then surely the love we commit to one another must be equal as well, which is significant towards equality among all because no matter skin color, physical features, or what you identify yourself as, it should not matter or compare to any one being.As he implements this form of credibility into the rest of his speech, the president lists the current issues facing our society today, and how we, as one unit, can tackle the issues, pursuing to solve them. He alludes to many events that have taken place in the past year at the time such as the hurricanes that swept away a home, and gun violence in relation to child safety. These real issues help draw the listener back into the reality from the vision of just equality. Finally, President Obama calls for action by reminding us, through anaphora, that our journey is not complete until we are all equal and more open to opportunity, also Obama tells us that it is our task, alluding to the Declaration of Independence, to make these words, rights, these values of life, liberty, and the pursuit of happiness real for every American is a task that we all as Americans will face together as one to conquer for all. Concluding his speech, the president reminds us that we, himself included with the audience are the hope, and the change that is needed to be in action. Obama signs off his address thanking God and proclaiming that may He forever bless these United States of America. For the final push of ethos gathering all emotions at the end to conclude the speech.
