The Causes Of Development Of Cancer - 945 Words

My main focus for this essay was to learn the main causes of development of cancer and just a better overall understanding of cancer as a whole because it is related to a few of the units we have covered. Cancer is a word that no one wants to hear or read about, but many are faced with this word every day. It can affect people of all ages and genders. According to the Canadian Cancer Society, cancer is a disease that starts in our cells. Genes inside each cell instruct the cell to grow, work, reproduce or die. When cells follow all instruction normally, everything works just fine. However, when cells get instructions wrong, cells can form tumors or lumps. They can also spread throughout the bloodstream and lymphatic system,†¦show more content†¦Commonly, a mass of malignant cells is called a cancer. Oncogenes, tumour suppressor genes and DNA repair genes are three types of cancer genes. People may inherit a mutated version of one of these genes which will make them more likely to develop a certain type of cancer. Oncogenes cause cells to grow out of control and promote cancer cell growth. They are a damaged version of the normal proto-oncogenes in our bodies. Tumour suppressor genes are genes that would, in a healthy person, protect us from cancer. They help us stop cell growth and control cell death. When these cells are missing or damaged they cause cell growth, division and death to be uncontrolled. According to the Canadian Cancer Society, â€Å"nearly 50% of all cancers are thought to involve a damaged or missing tumour suppressor gene.† DNA repair genes are responsible for repairing damaged genes. During copying of DNA, if mutations occur, they are there to fix the mistakes. These three genes are the main causes of cancer related mutations. Cancer development is a long process involving many steps. Usually it takes many years because several genetic mutations are required. Typically, many years pass between exposure to a cancer causing event or agent and the cancer actually developing. Typically, we see cancer in older ages because mutations have built up and they may have had more

Sigmund Freud s Theory Of Dreams - 1259 Words

Sigmund Freud was instrumental in developing many theories. Of the many ideas and contributions he made to research, his analysis of dreams was one of the greatest. Today, his theories are both recognized and disputed, bot nonetheless, significant. Freud incorporated the conscious, unconscious, and developments of thinking into his theories in his book, â€Å"The Interpretation of Dreams.† In The Journal of the American Psychoanalytic Association’s, â€Å"Another look at Dreaming: Disentangling Freud’s Primary and Secondary Process Theories† Michael Robbins, 20014, adds to Freud’s theories with his own, and analyses previous theories as well as explains how we interpret dreams. According to Freud, one must first understand the levels of consciousness to understand his theory of dreaming. The conscious level is what we are aware of. They are the normal day to day activities/thoughts we recognize exist. (Cervone Pervin, 2013) The preconscious are t he mental contents which we could become aware of, if brought to our attention. (Cervone Pervin, 2013) For example, you may not be currently thinking of what you had for breakfast this morning, but if someone asked you, you should be able to recall this information. The unconscious are thoughts a person is unaware of and cannot be brought to the conscious. (Cervone Pervin, 2013) For example, a traumatic experience provoking anxiety, may cause someone to force the incident or thoughts about the incident into the unconscious to protectShow MoreRelatedSigmund Freud s Theory Of Sexuality, And The Interoperation Of Dreams1289 Words   |  6 Pages Sigmund Freud An Overview of Two Theories Jace Moselund Palm Beach State college 12/02/2015 â€Æ' Sigmund Freud was born in Freiberg, Moravia on May 6TH 1856 in a Jewish family.

The article states how some people may experience anxiety about job stability and growth become overarching. In addition, they may fear that they will not be fortunate enough to retain their jobs, whereas others are simply unwilling or unprepared to learn and develop new skills. Communication breakdowns within an organization may contribute to resistance in changing organizations. Managers must be prepared to talk candidly about the needs for change, otherwise fear and uncertainty will remain a prevailing element that can damage morale and prevent successful implementation of the desired changes at all levels of the organization.

The Issue Of Morality, Virtue And Ethics - 2018 Words

The issue of morality, virtue and ethics are all elements that must be considered as Maxine, her husband and the Rackley’s move forward with a decision. Consequently, Maxine must understand and come to terms with the ideal that the right to life constitutes more than just the breathe of life, but rather the opportunity to live a whole and fulfilling life, at the same time that this right to life does not occur at the expense of the lives of others (Thomson 1971). In considering the impact of this decision on the unborn child, on herself, her three year old son, her husband and the awaiting couple, it is advised that Maxine acknowledge that it is the effect of her action which will render it morally sound, not the action in itself (Encyclopedia of Philosophy, . She must, therefore, act in a manner which would bring about the highest possible level of utility. Maxine must opt to terminate the pregnancy in order to spear the unborn baby an impending life of grief, illness and pain. She must spare the awaiting parents the agony of watching a child live a tortured life, and she must afford her son the opportunity to be raised by two healthy and able-bodied parents.

Like other forms of consequentialism, its core idea is that whether actions are morally right or wrong depends on their effects.

Why Do I Want to Become a Teacher Free Essays

All of my experience for the past 10 years since I have been in USA led me to realizing that I am passionate about teaching and working with children. I migrated to this country from Slovak Republic right after graduating from Comenius University with the major in Biochemistry. Being only 22 years old I wanted to experience some adventure before getting the regular 9-5 job at some Research Laboratory. We will write a custom essay sample on Why Do I Want to Become a Teacher or any similar topic only for you Order Now I signed up for a Summer Program with YMCA and came to Poland, Maine as a summer camp counselor. The environment was just beautiful. These little wooden cabins located on a beautiful Lake Sebago. That’s where my passion for working with children began. I was spending that summer with kids who were coming from broken and low income families from outside of Boston. I was responsible for a group of young girls, 7-10 years old. I and the girls bonded really quickly. Every day was different. Different fun, different drama, different atmosphere. And I loved every minute of it. I loved being creative with all kinds of activities, I loved being a leader who the girls looked up to and we had tremendous fun. I felt like I was making a difference in those children’s lives. At least for those few summer months those girls felt safe, nurtured and cared for. And I felt fulfilled and useful. After few years working in customer service I returned back to working with children. This time I took on a nanny job. I again experienced creating a strong bond with the boys I was taking care of. Their parents were divorced and the boys were switching between the two households each week. I felt that I brought a sense of calm and peacefulness to their lives. I lead them through their homework, different projects, we did all kinds of activities but most importantly we were having good and memorable time. Once they got older and got busier with their school and afterschool activities I had more time on my hands so I took it a step further and started tutoring chemistry and science. That`s where I felt the strongest fulfillment. To see my students succeed was the biggest satisfaction and I immediately knew that I wanted to become a teacher. I think teaching is adventurous, challenging, exciting job and personally very rewarding career. Working with students, every day is different; there is no room for routine or boredom. I am passionate about science and I want to share my knowledge with students. I have to say that I came a long way. It took me little longer than it takes other people to figure out â€Å"what do I want to be† but I feel positive and happy about my decision and cannot wait to step into a real classroom as a new teacher one day.

Bacterial Growth Requirements free essay sample

Growth Requirements Evelyn Lyle ITT Technical Institute Angela Ask, MPS January 15, 2012 Every organism must find in its environment all of the substances required for energy generation and cellular biosynthesis. The chemicals and elements of this environment that are utilized for bacterial growth are referred to as nutrients. Many bacteria can be identified in the environment by inspection or using genetic techniques. The nutritional requirements of a bacterium such as E Coli are revealed by the cell’s elemental composition. These elements are found in the form of water, inorganic ions, small molecules and macromolecules which serve either a structural or functional role in the cells. Bacteria thrive by four things oxygen, food (nutrients), warmth and time but two others can be moisture and acidity. Nutrients are needed for energy, nitrogen (for DNA and proteins), phosphorus (for energy), and others. Warmth is needed so the bacteria can stay warm. Oxygen is needed so the bacteria can make energy and time is needed for the bacteria to complete binary fission over and over again. We will write a custom essay sample on Bacterial Growth Requirements or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Acidity is needed so the bacteria can survive in its environment. Highly base or acidic environments may harm the bacteria and hinder its lifespan. In order to survive and grow, microorganisms require a source of energy and nourishment. Bacteria are the most primitive forms of microorganisms but are composed of a great variety of simple and complex molecules and are able to carry out a wide range of chemical transformations. Depending on their requirements and the source of energy used they are classified into different nutritional groups. Most microorganisms grow well at the normal temperatures favored by man, higher plants and animals. Certain bacteria grow at temperatures (extreme heat or cold) at which few higher organisms can survive. Most bacteria grow best in an environment with a narrow pH range near neutrality between pH 6. 5 and 7. 5. Microbes contain approximately 80-90% water and I f placed in a solution with a higher solute concentration will lose water which causes shrinkage of the cell. Some bacteria have adapted so well to high salt concentrations that they actually require them for growth. Nitrogen and phosphorus are particularly critical because they often control the rates of photosynthesis. Carbon is significantly more abundant than either of them and oxygen and sulfur are more abundant that phosphorous. Nitrogen and phosphorous are less available to plants relative to their growth requirements than are other elements. Phosphorus is often in short supply and limits plant and algae growth. Nitrogen is a major constituent of all proteins and of all living organisms. A lack of nitrogen can limit growth of plants, since nearly three quarters of its atmosphere consists of natural gas, N2.
