The study of a panda Essay Example

The study of a panda Paper The panda is black and white, like a bear in shape, but different. Things to remember in the last hour before the exam: Life processes at the cellular level (This is not a revision sheet youve done that by now Its a list of things you might want to remind yourself about 1. Cell parts. Most structures/organelles common to animal and plant cells. [P] = plants only C] Cytoplasm transparent Jelly ? cells activities occur here CLC Cell/plasma membrane regulates movement of materials in/out of cell. SELECTIVELY permeable. Phosphoric belayed. Phosphate heads (hydrophilic) face inside cell/outside cell. Fatty acid tails of lipids (hydrophobic) to interior. Small molecules e. G. Water diffuse through. Larger ones transported via protein channels. 0 Nucleus cell control centre, controls metabolism via enzymes. Contains genetic info DNA. Chromosomes only visible when cell is dividing. Contains nucleolus makes RNA and ribosome. Cell wall [P] protects cell gives strength and support. Is permeable and made of cellulose. Controls turgidity (can resist high internal pressures without stretching). 0 Chloroplasts [P] site of photosynthesis, contain chlorophyll green light-trapping pigment. Elongated shape maximizes S. A. To volume ratio, Increasing uptake of CO and H2O uptake and output of 02 and glucose (photosynthetic capacity). Chlorophyll molecules embedded In grand (stacks of ethylated membrane) more S. A. More chlorophyll = Max. Amount of light captured = more photosynthesis. Surrounded by stoma enzymes and water. 0 Large (central) vacuole [P] large and permanent structure containing cell sap (salts, sugars, amino acids). Salts in sap produce strong tendency for water to enter cell (by osmosis) keeping cell turgid.

Also short gas diffusion distances. 0 Mitochondria site of aerobic respiration. Enzymes attached to Cristal (membranes folded to Increase the S. A. = greater # of enzymes) produce ATOP (adenosine troposphere). Occur In high numbers In cells with large energy needs e. G. Sperm muscle cells. 0 Googol flat disc shaped sacs modify and package proteins C] ERE: Rough has bound ribosome (site of protein synthesis) makes proteins and transports proteins to Googol. Smooth has free ribosome makes steroids, lipids and hormones 2. Specialized cells perform specialized functions in multicultural organisms. Examples include: 0 Guard cells form stoma (small opening in epidermis) when turgid. Turgid = crescent moon shaped, flaccid = oval shape. Thick inner walls help them open/close stoma. Allow CO and 02 in and out. Also main route of H2O loss via transpiration. Swelling of vacuole controls opening/closing. Contain chloroplasts. 0 Palisade cells long, thin column shaped cells many can fit close together. Contain MANY chloroplasts. Cells arranged vertically so light passes through less cell walls to cells beneath. 0 Spongy mesosphere (beneath palisade layer) has more rounded not so tightly packed cells. Large Intracellular alarm spaces maximizes diffusion rate of gases during photosynthesis. (CO In 02 out). CLC Root hair cells Long and thin extension at one end with thin cell to vastly increase S. A. For absorbing small BIOLOGY Dont forget to throw this away DO NOT take it into the exam by mistake We dont want you disqualified by mistake 3. Movement. Three main mechanisms. Diffusion: Movement of substances from high concentration to low concentration along a concentration gradient which exists until diffused substance is evenly distributed. Passive movement. E. G: CO diffusing in / 02 out of leaf (through tomato). Note: can occur Just in solutions, as well as across membranes. 0 Osmosis: Movement of H2O from high concentration of H2O to a low con. Of H2O water through semi/selectively permeable membrane ( from a more dill. Solution to a more con. Solution). Passive movement. E. G. Absorbing water through plant roots, kidney tubules reabsorbing water. Active transport: Movement from a low con. To a high con. Energy is required. E. G. Absorption of MGM by roots, glucose uptake in intestines. 4. Enzymes. Protein molecules acts as biological catalysts increase rate of reactions. Substrate = molecule the enzyme acts. Increase in substrate concentration = increase in rate up to a maximum. Enzymes are specific have AD shape with unique active site only work on a particular substrate. Function best in particular conditions e. G. An optimum temperature and optimal PH. (function poorly outside these). At very low temperatures, enzyme action slow; as temp. Increases reaction rate increases (more collisions/time) BUT at high temperatures enzyme is denatured (peptide chains unravel active site is lost enzyme is permanently inactive). CIO every ICC rise enzyme activity approve.. Doubles. Co-enzymes complete the active tit essential to enzyme action. Inhibitors (poisons) combine with active site to prevent enzyme function. 5. Photosynthesis. Needs CO via stomata, H2O via roots and xylem, sunlight and chlorophyll. CHIC + AH 0 C6H1206 + 602. Sunlight needed as source of (solar) energy. Rate affected by light: more light = more photosynthesis up to point where plant is at Max. Photosynthesis level any increase in light intensity wont affect the plant further. Rate at midday >early morning [evening. No photosynthesis at night. Rate in summer > winter. Temperature affects rate. 6. (Aerobic) Respiration. C6H1206 602 0 CHIC + AH. Breakdown of glucose occurs in 2 steps glycoside in cytoplasm, then Krebs/citric acid cycle in the matrix of the mitochondria and electron transport system on Cristal of mitochondria. Energy from food (from breakdown of glucose and fatty acids) converts ADAPT + P 0 ATOP. ATOP = the energy carrier / energy in a usable form. ATOP is broken down elsewhere to ADAPT + P releasing useful energy for cellular work. 7. Cell division. 0 A cell cycles between periods of cell division, growth, normal activity (enterprise) and back to division. DNA replication occurs DNA makes exact copy of itself prior to ell division so there is a full set of genetic information available in each cell after division then preparation for mitosis then mitosis. The cycle repeats. DNA contains code for synthesis of proteins in its base sequences. All cells need the code to synthesis essential proteins for the cell to grow and carry out its role. DNA must replicate accurately so all new cells have a complete copy of the code. 0 Key steps. DNA helix unwinds, two strands unzip between bases, new nucleotides Join to the enzymes. Base pairing (A-T and C-G) essential provides mechanism accurately making two identical DNA molecules.

Dopamine and its Role in Parkinsons Disease Research Paper

Dopamine and its Role in Parkinsons Disease - Research Paper Example The researchers in this study stated that there appeared to be a link between depression and anxiety in PD.   According to Lemke, these studies proved that dopaminergic treatment for PD was important and that there was a correlation between PD and depression. 1.1 Dopamine Agonists and Depression According to Lemke, dopamine agonists work on the dopaminergic systems of the body (10). Because they work directly on these areas, they may be responsible for mood behavior. One dopamine agonist, pramipexole, was studied by other researchers and found to react as an antidepressant for bipolar disease and treatment-resistant depression (10). Several studies in this study showed that patients who took pramipexole performed better and were less depressed than those who did not take it (11). 1.2 Anhedonia and Depression Anhedonia is another agonist that has had positive effects on depression with PD patients and it has also affected any motor alterations (11). Several studies were quoted in Le mke’s article that used this agonist. All of the other studies found that patients with PD were helped via the use of agonists by controlling depression. Lemke concluded that PD patients with depression â€Å"might† benefit from a global approach to the disease that included dopamine agonists because they seemed to reduce motor complications and symptoms of depression. By using agonists the regimen of drugs could be lessened and would stop any side effects from the antidepressant medications that the patients may be taking.

Sir Richard Bramson and the Virgin Group of Companies Essay

Sir Richard Bramson and the Virgin Group of Companies - Essay Example The success of his prestigious group of companies is a confirmation of his ability to apply the necessary management skills and strategies required for successful businesses. Sir Richard Branson had no initial intentions of becoming an entrepreneur although this did not prevent him from building his status as one of the most successful entrepreneurs globally. Having launched a student magazine at the age of sixteen and managed a student advisory centre, Branson had a background in business establishment and management i.e. habitual entrepreneur (Branson, 2011; Shavinina, 2008: 9-15). However, the success and expansion of the Virgin Group led to incorporation of other business ventures making him a portfolio entrepreneur. Some of the personal entrepreneurial characteristics that have enabled Branson to emerge as an exemplary entrepreneur include his high level of motivation, high levels of self confidence, abundant energy levels and the ability to sustain the entrepreneurial approache s in long term (Branson, 2011). Additionally, he has exhibited his worth as a risk-taker, the ability to set achievable goals, innovation and a problem solver (Bolton and Thompson, 2000). He variably contributed to the entrepreneurial sector through the establishment of a brand image and identity of the Virgin Company in the global markets. The company’s marketing strategies prioritises on the customers; improving loyalty. His management skills have led to the growth of the company to international standards. The employee commitment that the company exhibits indicates that Sir Richard Branson possesses effective employee management skills that keep employees always motivated. The dedicated and united employee team has utilised the business and marketing strategies associated with the business to constantly enable the business improve performance. Application of these strategies in all marketing segments has enhanced the application of innovation in all marketing segments. Ana lysis of the Virgin Group of companies exemplifies the entrepreneurial characteristics of Branson. Entrepreneurship can be defined as a process whereby individuals or group of individuals apply organised efforts in the pursuance of opportunities (Kuratko and Hodgetts, 2004). An entrepreneur should target to create value and growth through innovation and maintenance of uniqueness. This has been the main factors that have enabled Virgin Group of companies to be successful since its establishment. According to Shavinina (2008), the formation and management of the affiliate companies of the Virgin Group exhibits adherence to the entrepreneurial process. The initial stage of the process involves the exploration of the entrepreneurial context. For instance, the establishment of Virgin Airlines was Branson’s attempt to offer reasonable freight charges for transatlantic flights. The second stage involves identification of the possible opportunities that guarantees competitive advanta ge. The venture is then established once the opportunities are identified paving way to management once all its structures are in place. According to Carmichael (2006), Branson’s skills portrays him as a transformational entrepreneur due to his insistence on maintaining Virgin Group of companies as an organisation characterised by informality and

Technology Addicts :: Technological Communication Essays

Technology Addicts Five empty chairs form a circle in the center of the room. Slowly but surely, people begin to make their way into the room. A young man dressed in a black suit sits down with his Newsweek and briefcase. He adjusts his tie, clears his throat, and pushes his wire-rimmed glasses up onto the bridge of his nose. A teenage girl sits down beside him, tucking blonde strands of hair behind her ears to reveal tiny white headphones attached to her iPod. She crosses her right leg over the left, tapping her foot in mid-air to the beat. The worn wooden door creaks open again, slamming shut behind a twenty-something carrying a thin silver laptop computer. He slouches down into the chair with an exasperated sigh and begins to type furiously at the keyboard. The businessman glares over the top of his glasses at him when the familiar chimes of instant messaging become as frequent as the taps of the keys. The young man continues, oblivious to his surroundings. The clock on the wall ticks closer to seven o'clock as the last two people amble in. A middle-aged woman sits down with her knitting, occasionally stopping to jot notes in the sleek PDA beside her. Finally, a woman with a clipboard comes through the door and takes her seat, completing the circle. She clears her throat and begins. "Good evening, and welcome to group therapy. Let's go over the ground rules: First no technology allowed at meetings. Put away your iPod, laptops, PDAs, etc. RIGHT NOW. And don't bring them back to these meetings or they will be confiscated." The group members scowl as they slowly wind up wires. "My only other rule is that you participate. You won't get anything out of group therapy if you don't put anything into it. Let's begin." * * * What would our lives be like if technology were our life support? We would probably not be able to go an entire day without emails, instant messaging, or the World Wide Web. Cell phones might as well be permanently attached to our ears.

Immanuel Kant †Ethics Essay

Immanuel Kant was born in Konigsberg, East Prussia in 1724. He attended the Collegium Fridiricianum at eight years old where he was taught classicism. Then he went to the University of Konigsberg where he spent his career focusing on philosophy, mathematics, and physics. When his is father past away, Kant left the university and earned his living as a private tutor. In 1755 he returned to the University to receive his doctorate in 1756. Immanuel Kant remained at the University teaching for 15 years. He received his tenure at the University in 1770, where he stayed for the next 27 years. In 1792 he was barred from teaching or writing on religious subjects do to his unorthodox approach in his teaching by King Fredrick William II. He returned to teaching after the king had passed away five years later. In his retirement he published a summary of his views on religion. Immanuel Kant passed away in 1804. Immanuel Kant was widely known for his categorical imperative theory. Categorical imperative is how one determines one’s duty, what principles are proper, and which are not. Doing one’s duty for the sake of duty itself is better than simply acting in agreement with one’s duty. Telling the truth in order to benefit yourself is acting in accordance with duty and not acting for the sake of duty. The categorical imperative states, â€Å"Act only on that maxim whereby thou canst at the same time will it should become universal law(Keele, 2008). † Maxim in this sentence is the moral part of your action. Categorical imperative tells us it is immoral to make an exception of our self. Just like my mother would say treat and act as you would want others to treat and act towards you. In the news I view an article about â€Å"School knife attack poses ethical dilemma for daily. † In this article they talk about the Worcester New identifying a schoolboy as a suspect. The news published the boy’s name and picture on Facebook putting the boy’s life at risk. After the boy was found the news took down the boy’s picture at once. Everyone was perplexed by this situation asking why they put picture up and then took it down. According to the Worcester News, the situation change, where they were trying to find the boy to stop him from hurting himself or others and then to protecting the child. Would the newspapers actions have been ethical according to Immanuel Kant’s Categorical Imperative? First let’s take a look at the reasons why they did it. The newspaper stated they put his picture up to protect him and other, then took down to protect him. I believe they were acting in the best of society myself by putting the information up. According to Immanuel Kant’s theory they were acting in accordance with their duty. They had a duty to let the public know what was going on to protect other students and teachers If they didn’t act with such speed would the boy have been found so soon? I think not! This boy could have went on a killing spree and if the Worcester News didn’t report it they would not have been acting in the best of society and would not have been doing their duty. But then to take down the information I feel is unethical. They don’t take down any information when it comes to any other person involved in a crime. Immanuel Kant stated that it is immoral to make an exception of yourself. The Worcester News should hold to the same standards as any other crime they report. I understand that they are trying to protect the boy, but if you are going to report any other crime and not take it down this should happen in the same way. In conclusion, based on my research I feel that Immanuel Kant’s Categorical Imperative theory is important to our society today. It holds everyone to the same standards! He has help to maintain a set of standards for our society that requires everyone to be treated the same. The study of ethics is important in today’s business and government world because it sets standard for all to abide. From John Locke’s right theory to Kohlberg’s moral development stages. They all 1 / 2 set standards in which business need to stay within. If there were no standards there would be more scandals in the news than there is. References Britannica. (2014). Immanuel Kant.
