Biology Question and Answers Temperature, Substrate, Concentration - 1100 Words

Biology Question and Answers: Temperature, Substrate, Concentration (Term Paper Sample) Content: Biology1. The first law of thermodynamics states that energy can neither be created nor destroyed but can be transferred from a system to the surrounding. In the cleip, energy is changed from chemical energy(candle wick) to thermal energy(lit candle), heating up the copper tubing and water inside into a mechanical energy(the steam propelling the boat forward) Heat flows from the the candle to the copper tubing and finally into water. That way, energy has been transferred.2.The second law of thermodynamics states that the entropy of a system always increases.If you took two beakers of the same volume of water and temperature, then drop a dye simultaneously on the beakers. You will realise that the pattern of distribution of the dye is is different but ultimately the end result will be same. An even colouration of the water in the beakers. This is what is called the randomness of Brownian motion due to increased entropy of the system.In the second experiment, two beake rs with the same amount of water, A at 30 and B at 90 were taken. A dye was added to each beaker simultaneously. The rate of diffusion of the dye was slow in beaker A and very fast in beaker B. Note that every other factor was constant except for temperature that was the only manipulating variable. Ultimately, the solutions have even distribution of the colour. This shows that the particles are propelled by thermodynamic energy. This shows that higher energy possessed by the particles increases the rate of diffusion. The distribution of the solute molucules is thus randomised throughout the entire system. Thus entropy increases.3.Substrates bind to the active site of enzymes to form enzyme-substrate complex. The enzyme then increases the rate of reaction by lowering the activation energy of the reaction.Factors affecting enzymatic actionsÐ ²Ãâ€šÃ'ž TemperatureÐ ²Ãâ€šÃ'ž Substrate concentrationÐ ²Ãâ€šÃ'ž pHÐ ²Ãâ€šÃ'ž Enzyme inhibitors4. Differences between diffusion and OsmosisOsmosis is the movement of solvent molecules from a region of low concentration to a region of high concentration while diffusion involves the movement of molecules down their concentration gradient.Whereas osmosis involves only the movement of solvent molecules, osmosis involves both the movement of solutes and solvents molecules.5.Examples of OsmosisÐ ²Ãâ€šÃ'žReabsorption of water from the kidney tubulesÐ ²Ãâ€šÃ'žOsmosis when washing leads to wrinkling of handsÐ ²Ãâ€šÃ'žKidney dialysisÐ ²Ãâ€šÃ'žFeeding in insectivorous plantsÐ ²Ãâ€šÃ'žAbsorption of water for support by herbaceous plantsExamples of diffusionÐ ²Ãâ€šÃ'žPerfume filling the whole roomÐ ²Ãâ€šÃ'ž Diffusion of carbon dioxide into the leaves through the stomataÐ ²Ãâ€šÃ'ž Uptake of water from the soil through the root hairsÐ ²Ãâ€šÃ'žDiffusion of oxygen from alveolar spaces into the bloodstreamÐ ²Ãâ€šÃ'žRelease of oxygen into the atmosphere after light stage of photosynthesis6.Definitely yes. It helps in keeping the vegetables fresh and avoids wastages.7. Red blood cells in isotonic solutionsThere is a unique phenomenon when red blood cells are placed in an isotonic solution, there is no net gain or lose of water from the cell. As such, the cell neither swell nor shrink. The reason behind it is water enters and leaves the cell at the same rate because the concentration out and inside the cell is the same. Red blood cells in hypertonic solutionsA red cell placed in a hypertonic solution will lose water by the process of osmosis and shrink, a process called crenation. Here, water moves from a region where it is highly concentrated to a region where it is lowly c...

Learning 2.0 is technology enhanced learning that goes beyond access to traditional educational materials and tools to construct a style of learning that is more engaging for the student; this is accomplished through the demand-pull approach which presents students with a vivid, possibly virtual, learning construct. This self-regulated learning process is based on the student’s desire to learn about a particular topic or be a part of a certain community, and is usually informal. The demand-pull mode is resource-oriented and current internet sources. Web 2.0 is rapidly growing and evolving (Brown Adler, 2008). The benefits and challenges that may be associated with self-regulated learning are (1).Staying Engaged, the internet along with the various applications help keeps students engaged on a particular topic of interest.

Essay about Sociological Concepts in Wheres the Love

The song â€Å"Where’s the Love?† by Black Eyed Peas displays many sociological concept in the context of its lyrics. In this song the band is expressing their concerns with the world’s views and actions of the present day. They question the mentality and reflect upon the realism of the world. The main idea surrounding this song is concentrated around the social construction of reality and how the world is changing. The song expresses the way people are not living up to society’s norms and values. It suggests that various agents of socialization are at fault and that they contribute to the development of self. This song implies that individual’s are violating the norms and values of society. They start the song with a verse that expresses†¦show more content†¦These are countercultures which are smaller groups within a certain culture group that are in opposition to all the behaviors and norms of the larger group. (Newman, 124) These count ercultures contribute to the violation of norms and values of the dominate group. This song is concentrated on the social construction of reality, which talks about about how â€Å"Ideas about reality also change over time† (Newman, 53). We can see this expressed in lines 32-33 in the song : â€Å"It just aint the same, old ways have changed/New days are strange, is the world insane†¦Ã¢â‚¬  (lines 32-33) The band states how the world’s views and attitudes have changed and how there is uncertainly for the future. The band is questioning the values that they once lived up to. â€Å"Yo, whatever happened to the values of humanity/Whatever happened to the fairness in equality/ Instead of spreading love were spreading animosity/ Lack of understanding, leading lives away from unity†¦Ã¢â‚¬  (lines 71-74). They imply that individuals are swaying away from their values, as a result changing their reality. In addition, they also question the faith and actions of the world.

Music in the reflects Essay Example For Students

Music in the reflects Essay Music in the sasss reflects cultural and social conditions that surrounded Americans during The Great Depression and Dust Bowl. Music during this time also exhibits a glimpse of hope for America and its people. Even though this time frame was full of economic strain, music gave hope to Americans. From Jazz and swing music on the radio, to dancing in ballrooms and clubs, music produced a positive motive in one of the toughest times in American History. The most important things to remember about music in this era are, Jazz and swing music, dances of the time, economic factors of music, and finally the social and internal effect on the people. Music during The Great Depression had a great impact on people. Introduction into music standings and the effects of The Great Depression In the early thirties old records were literally burned to survive in the winter. The music industry is in a complete downhill spiral. From selling over 100 million records per year to 6 million per year. Instead of records, radios and radio programs were sold. Now everyone was able to hear all kinds of music for free, which was more popular with people. Things started to look back up for the music industry. Jazz music became very popular on the radio. It possessed a symbol of American freedom from the chains of the depression. After the rise of the radio things skyrocketed for Jazz bands and record labels. Jazz and Swing Music First and most important is Jazz and swing music. It recovered the failing music industry. It was founded by African Americans in the south and was considered dangerous at first. Jazz bands consisted of a band lead and fifteen to twenty instrument players. Jazz music took a hard blow Just like the rest of the music industry did in the early sasss. But in the mid sasss the Swing Era emerged and changed everything including the mind set of the depression people continued to suffer from. Jazz differed from swing in one way, being that swing focused on Jazz arrangements rather than pop tunes. Which enables people to focus on dancing rather than singing which is discussed later. The fun upbeat melodies of swing and jazz songs set people free. Jazz music brought entertainment to a struggling people. It gave them a break from everyday life. For a moment they could put it all aside and once the night away and be free. (Music in the sasss. ) The known creator of the Swing Era was a trumpeter named Louis Armstrong. He increased importance of solos which in all turned Jazz music to swing music. An African American named Duke Longtime is know as the greatest composer of the era. He left thousands of pieces ranging in all genres but mostly in swing and Jazz. Longtime started his career by studying and playing classical music until Jazz caught his attention. At this time America was segregated but when The Duke was playing no one, including whites could look away. He amazed people with what as known as his Jungle style. Dances of the sasss as dance marathons. Couples would compete in competitions against other couples. The main reason people Joined these dance-offs was money. Monetary prizes were often the result of winning. Competitions usually lasted six months because there were so many desperate participants. If the couples knees touch the ground they are automatically disqualified. Joining was usually a result of economic problems. Some who Joined had no idea how to dance. The two most popular dances of the time were The Big Apple and Lindy Hop also now as the Jitterbug. .uc41f99d518fe0afc3de8eaff077527fb , .uc41f99d518fe0afc3de8eaff077527fb .postImageUrl , .uc41f99d518fe0afc3de8eaff077527fb .centered-text-area { min-height: 80px; position: relative; } .uc41f99d518fe0afc3de8eaff077527fb , .uc41f99d518fe0afc3de8eaff077527fb:hover , .uc41f99d518fe0afc3de8eaff077527fb:visited , .uc41f99d518fe0afc3de8eaff077527fb:active { border:0!important; } .uc41f99d518fe0afc3de8eaff077527fb .clearfix:after { content: ""; display: table; clear: both; } .uc41f99d518fe0afc3de8eaff077527fb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uc41f99d518fe0afc3de8eaff077527fb:active , .uc41f99d518fe0afc3de8eaff077527fb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uc41f99d518fe0afc3de8eaff077527fb .centered-text-area { width: 100%; position: relative ; } .uc41f99d518fe0afc3de8eaff077527fb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uc41f99d518fe0afc3de8eaff077527fb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uc41f99d518fe0afc3de8eaff077527fb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uc41f99d518fe0afc3de8eaff077527fb:hover .ctaButton { background-color: #34495E!important; } .uc41f99d518fe0afc3de8eaff077527fb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uc41f99d518fe0afc3de8eaff077527fb .uc41f99d518fe0afc3de8eaff077527fb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uc41f99d518fe0afc3de8eaff077527fb:after { content: ""; display: block; clear: both; } READ: Music history Argumentative EssayThe Big Apple was popularized and invented by African Americans. It was a circle group dance that allowed individuals to shine. It included swing steps combined with square dancing. Daytime Publications says: It was popular during the Depression because of the psychological comfort it gave of strength in numbers. Out of the two dances, the Jitterbug was the most popular. It requires mass strength and agility. It was named The Lindy Hop to start off with because of tribute to Charles Lindbergh historic first solo transatlantic flight in 1927. This dance involved intense acrobatics and gymnastics. The term Jitterbug also means the best dancer because you had to be incredibly skilled to perform it correctly. Musicals After the rise of the music industry, America started to incorporate music into movies. Musicals become popular and prominent in the time period. Hollywood wanted a happy distraction from the depression. Many famous songs came from movie musical, including Were in the Money from the musical Gold Diggers of 1933. The most famous song Somewhere Over the Rainbow from the musical The Wizard of Oz of 1939. One of the most favorites actress and singer was little Shirley Temple. She performed in many musicals during the thirties. The sight of her precious smiling red haired face lifted the hopes and spirits of America. Impact of Music on People From feeling down in the dumps to feeling like youre flying on cloud nine, music changed the lives of countless numbers of people during the sasss. It brought light to their dark depressing lives. Hope rose up from new grounds and people began to look positive towards the future. Music was the drug of the thirties. Struggling people could get through everyday with music. The uprooted American working class, black and white, used these musical forms to hold on to a sense of identity amidst the uncertainty of a changing world. (American Popular Music in the sasss) Conclusion Music played a huge role in The Great Depression. Without knowing anything about the music of the time you would probably think nothing of it. You would think it was Just music, but to them it wasnt Just music. It was a chance to live and be free in a time where everyone was broke and stressed out. Jazz and Swing music had the most effect on people, along with dances that correspond.

Information Technology Management Degrees and Careers

Information Technology Management Degrees and Careers An information technology management degree, or IT management degree, is a type of postsecondary degree awarded to students who have completed a college, university, or business school program that focuses on teaching students how to use computer software and systems to manage information. After completing the program, students should be able to find technology-based solutions to important business and management problems.   Types of Degrees There are three basic options for students who are interested in an information technology management degree. A bachelors degree is typically the minimum for most jobs in the information technology management field. Advanced jobs almost always require a masters or MBA degree. Bachelors Degree in IT Management: A bachelors degree in IT management is ideal for students seeking entry-level positions in this field. However, many information technology managers choose to earn a bachelors degree in information science, computer science, or information systems management instead. Regardless of the degree name, most bachelors programs take four years to complete and consist of general education courses combined with specialized courses in information technology and business management.Masters Degree in IT Management: A masters degree in information technology management or a related field is a requirement to work at some companies. It is especially recommended for advanced positions. A masters degree usually takes two years to complete once you have earned a bachelors degree. While enrolled in a masters program, you will study advanced topics in information technology. You will also take business, management, and leadership courses.Doctorate Degree in IT Manageme nt: The highest degree that can be earned in this area is a doctorate degree. This degree is well-suited for students who want to teach or perform field research. It can take anywhere from four to six years to earn a doctorate degree.​ Choosing a Program When choosing an information technology management program, you should first look at schools that are accredited to ensure you find a quality program with degrees respected by employers. It is also important to choose a school that has an up-to-date curriculum that focuses on the skills and knowledge you want to attain. Finally, take time to compare tuition, career placement rates, class size, and other important factors. Read more about choosing a business school. Information Technology Management Careers Students who earn an information technology management degree typically go on to work as IT managers. IT managers are also known as computer and information systems managers. They may be responsible for developing tech strategies, upgrading technology, and securing systems in addition to overseeing and directing other IT professionals. The exact duties of an IT manager are dependent on the size of the employer as well as the managers job title and level of experience. Some common job titles for IT managers include the following. IT Project Manager: Sometimes known as an IT Director, an IT project manager heads up a specific technology project. They may be responsible for managing upgrades and conversions. IT project managers typically have one or more IT professionals who report to them.

A Case Study About Healthcare Leadership

A Case Study About Healthcare Leadership Effective leadership is essential in health care organisations as in other organisations. It is necessary for driving innovation, effective patient care, patient safety, improving working within clinical teams, sorting out issues within emergency context and other aspects necessary for effective and efficient running of healthcare organisations. Transformational leadership has often been prescribed as the ‘gold standard’ of healthcare leadership(Gopee and Galloway 2009).This essay sets out to: briefly discuss the concept of leadership; highlight why leadership is important in healthcare; make a distinction between the closely-related concepts of leadership and management; briefly highlight how power relates to leadership; describe some leadership approaches applicable within the context of healthcare organisations; describe leadership styles visible in healthcare; present a case study set in a teaching hospital practice setting in Africa ; critically assess the leadersh ip approaches operating within the setting and its effect on organisational performance ;and make recommendations on improving leadership practice within the specified setting. What is leadership? Leadership can be defined as â€Å"the ability of an individual to influence a group of people to achieve a goal(Bryman 1992).It is also noted that ‘leadership can have four possible meanings, namely: the activity of leading; the body of people who lead a group; the status of the leader; and the ability to lead'(Gopee and Galloway 2009). Kouzes and Posner (2007) suggest some characteristics of an effective leader namely to: be more effective in meeting job-related demands; be more successful in representing their units in upper management; create higher performing teams; foster renewed loyalty and commitment; increase motivational levels and willingness to work hard; and possess high degree of personal integrity. Why leadership in healthcare? Effective leadership and management has been found to contribute to efficiency of health care services, performance (McColl-Kennedy and Anderson 2002) and satisfaction of staff employed within them.(Bradley and Alimo-Metcalfe 2008) researched the causal relationship between leadership behaviours and the performance and productivity of staff and found that ‘engaging leadership’ improved employee engagement and performance. (Morrison, Jones et al. 1997) studied the relationship between leadership style, empowerment, and job satisfaction on nursing staff at a regional medical centre. They used Bass’s Multifactor Leadership Questionnaire to measure leadership style, items from Spreitzer’s Psychological Empowerment instrument to measure empowerment, and the Warr, Cook, and Wall’s job satisfaction questionnaire to measure job satisfaction. The authors found that both transformational and transactional leadership were positively associated with job satisfaction. Some other researchers reported t hat good leadership skills impacted on patient safety and quality of care (Corrigan, Lickey et al. 2000; Firth-Cozens and Mowbray 2001; Mohr, Abelson et al. 2002).Furthermore, leadership skills are essential in the world of public health policy and leadership is one of the core competencies required of public health trainees(Faculty of Public Health 2010). Leadership versus management Relevant to this discourse is making a distinction between leadership and management. They are two similar but distinct concepts. Management is seen as seeking order and maintaining stability while leadership is seen as seeking adaptive and constructive change. Leadership in the healthcare context aims to influence practitioners towards the achievement of the common goal of quality patient care. On the other hand, management as a process coordinates and directs the activities of an organisation to ensure it achieves its set objectives. Management ensures healthcare resources (human such as doctors, nur ses and clerical staff and non-human resources like medical devices and consumables) are utilised in an efficient way whilst delivering effective healthcare service(Gopee and Galloway 2009). However, leadership is known to be complementary to management (Kotter 1999; Zaleznik 2004).
