Tavis Daluz-Cates Mrs. Cellini Genetics Period E 5/5/2016 Attention Deficit Hyperactive Disorder What is it? Attention Deficit Hyperactive Disorder is a disorder that occurs in the brain that results in a lack of attention and an impulse of hyperactivity. This can interfere with the person’s development and functioning. People who suffer from ADHD show patterns of inattention, impulsivity, and hyperactivity. In children, ADHD is shown to be more common in boys than in girls. Some studies report a high ratio of boys to girls. The inattentive type of ADHD is found more commonly in girls than in boys. People who have ADHD as children usually maintain the full diagnosis into adulthood. Even if they don t the children will have some residual symptoms of ADHD as adults. Families who have children with ADHD experience much higher anxiety and stress levels than families without. Many children will exhibit signs of ADHD by the age of four. However, most children are not diagnosed until they reaches elementary school. Living with ADHD can put children put at risk for a host of other problems and complications such as, alcohol and other drug abuse, completing their education, and an increased risk for delinquency. There has been been a lot of research on ADHD in recent years and many different types of medications and interventions have proven to be quite helpful or at least lessen the severity of the symptoms.

My Transformation Story - 1353 Words

I grew up as a young man in Lagos Nigeria, learning the values of hard work, contentment, focus and integrity from my mum, who singlehandedly raised I and my two sisters, having lost our dad when she was just twenty eight and just as I neared my third birthday. However, as I grew up, it was discovered that I was a very absentminded and forgetful kid, who secretly hated schooling, but was very vocal, inquisitive, loved to read autobiographies write articles and debate with classmates and teachers and quite surprisingly, I did quite well in elementary School and even was best student in the entrance examination into secondary school. I learnt from childhood that to succeed in life I should study hard, graduate, get a good job and work at†¦show more content†¦On the insistence of a close friend and with the support of my mentor, I returned to Yaba College of Technology and obtained a Higher National Diploma from the same department and graduated top of the class. During the p rogramme, the College closed for a full academic year and I took a job again in a start- up Estate Surveying firm, where I was responsible for major assignments. My mentor advised me to formulate plans for my working years and work towards becoming an entrepreneur eventually. I began to dream of running my own firm someday, but didn’t know how it would happen. As I prepared for graduation, I got a job as a Facility Manager and Project Liaison officer with a construction firm and worked there for three years, serving meritoriously, but the job was not demanding and as I was getting patronage from old friends and even my employers, I started my Property Services Company on the side. In June 2010, my employers decided that they wanted to relocate abroad fulltime and stop operations and since it was sudden, I had nothing to do but to commence running my company fulltime and have become quite successful, overcoming my start- up challenges, growing the company, learning from adversity and providing employment for myself and a few others and most importantly, earning respect and admiration of clients.

Includes Suggestion By The Project Manager-Myassignmenthelp.Com

Questions: What Is Going On? What Are The Facts? What Are The Issues? Who Is Affected? What Are The Ethical Issues And The Associated Implications? What Can Be Done About It? What Are The Options That May Be Used? Answers: 1.The scenario that has been selected for the case study includes the suggestion by the Project Manager to the Program Director to go ahead with the early launch of the project without the encryption. It has been suggested by the Project Manager on the recommendation of the CEO in order to gain more revenues and business opportunities (Youtube, 2017). 2.The Project Manager is not sure about the implications that the project may have in case of the absence of encryption from the project. Program Director; however, understands that the delivery of the project without encryption may lead to some serious implications such as security attacks and difficulties to the users (Bergold Thomas, 2012). 3.The CEO and the project client have urged to the Project Manager for early launch of the project. The Program Director has informed the manager regarding the issues such as security implications that may emerge (Heeney, 2016). The Manager has recommended that the fixes may be provided in the first security update. However, the delay in the inclusion of encryption can lead to violation of security and may impact the privacy of information (Glover, 2009). 4.Project Manager and his team will be affected as the early launch will lead to the impressive results in the beginning but occurrence of errors will be the accounting and responsibility of the project team. Project client will be affected as the decision to delay the launch may lead to adverse impact on the reputation (Birkholm, 2016).End users will also be affected as their information and data may be put to risk. Character Ethics 5.There are many ethical theories that have been defined and one of such theories is the theory of Character Ethics. As per the principles of this ethical theory, an activity can be termed as ethically correct only when the virtues that are involved are positive and lead to happiness. In this case, the Project Manager is willing to launch the project earlier due to personal benefits and selfish interests as it will provide him with better business opportunities. The Manager is ignoring the implications that his decision may have on the associated parties (Annas, 2014). Therefore, as per the principles of the theory of Character Ethics, the act included in the case study is not justified and is not correct as per the ethical principles. Theory of Consequentialism It is an ethical theory that says that the consequences of a particular activity determine the ethical justification of an activity. If the consequences that come out from an act are positive and cause benefits to all then the act is ethically correct and vice versa. In this case, if the decision is taken to go ahead with the early launch of the project without the encryption included in it, it may have negative consequences. The early launch will lead to the appreciation by the CEO and the project client to the project team and the project manager. However, in case of security implications, the client will get to know that the delivered project was defected and the same will lead to decreased customer trust and poor reputation in the market (Hoeyer, 2012). Since, the consequences that have been observed are negative in nature; the ethical correctness of the act cannot be justified. The act is ethically incorrect as per the theory of Consequentialism. Deontology Ethics This is the ethical theory that says that the act shall be based upon the rules and regulations that are defined in association with it. If the act does not maintain the adherence to the rules and guidelines, then the act cannot be termed as ethically correct (Mandal, Ponnambath, Parija, 2016). The primary rule of any project is to make sure that the customer and business requirements are met. Also, as per the rules of business and professional ethics, it is necessary to ensure that the professional and ethical codes of conduct are also met. There is a clear violation of all of these rules in this case and therefore, the act is ethically incorrect as per the theory of Deontology ethics. 6.The Project Manager must communicate the CEO and the project client regarding an important functionality that is missing which may lead to some of the severe security implications. A meeting shall be held with the Project Manager, Program Director and other project resources regarding the minimal time that may be taken to include encryption in the project (Ehrbar, 2015). 7.The following options may be used in this case: There shall be a revision of the project strategies and schedule to understand the least amount of time that may be taken to include encryption in the project. The Project Manager may seek for additional resources to speed up the tasks in order to fulfill the clients wish to receive the project earlier than the due date. If the time required to complete the project along with the encryption exceeds the earlier due date in all the scenarios, the Project Manager shall clearly communicate the security implications that the project may result in. Also, the plan to deliver the security update in the earliest fix shall also be informed. Conclusion Business ethics and professional code of conduct are the two parameters and necessities that must be reflected in all of the business processes and activities. In the case study, the Project Manager is looking at the immediate results that he will experience in terms of satisfied customer and increased business opportunities. However, in the long run, the decision may prove to be wrong as the project may experience security violations and other adverse results. The project resources must therefore understand that the use of incorrect and unethical practices will always lead to damage and loss. The business activities must be executed with utmost honest and correctness. References Annas, J. (2014). Applying Virtue to Ethics.

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.
