Exocytosis in Paramecium

In Paramecium caudate, trichinosis are IOWA secretors vesicles that are released from the cytoplasm. We first observed how the presence of Alicia blue dye triggers normal secretion of trichinosis, and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracurricular and intracellular environment affects the secretion of trichinosis.Our first our hypothesis tested whether extracurricular calcium is required for the secretion of trichinosis by reading cells with EST., an agent that blocks calcium ions; our second tested whether increased calcium will counter the inhibitory effects of EST.; our third tested whether adding different ion, like Magic, can also counter the inhibitory effects of EST.; and our fourth hypothesis tested whether the release of intracellular calcium by adding caffeine or oenophile affects exoticism.Our results demonstrate that exoticism of tricycles is dependent on the presence of calcium ions in both the intracel lular and extracurricular environments. Introduction: Exoticism in eukaryotic cells is the process in which macromolecular material is released from the cell into the extracurricular environment; one example of exoticism is the secretion of trichinosis in paramecium. Trichinosis are secreted from the cell as a defense mechanism when certain stimuli are introduced into the extracurricular environment.The secretion of trichinosis is controlled by the presence of Ca*+ ions within the plasma membrane and in the extracurricular environment. The purpose of our experiment was to observe the extent to which exoticism is pendant on the presence of extracurricular and intracellular calcium ions, and to determine if other extracurricular ions can have the same effect as calcium. The cells were first treated with 0. 03% Alicia blue dye, which triggers normal exoticism. Cells were then treated with EST., an agent that inhibits calcium, in order to observe how triptychs secretion is affected when calcium ions are sequestered.Additional calcium ions were added to the extracurricular environment to determine if the effects f EST. could be countered by increasing calcium. The cells were then exposed to a different ion, Magic, to observe if a different ion could have the same promoting effect in the extracurricular environment as calcium. Finally, the effect of intracellular calcium was tested by treating cells with a calcium oenophile (A23187) and caffeine, which both stimulate the processing of calcium into the cytoplasm of a cell. Results: Table 1: Observations of triptychs secretion in Paramecium caudate.Data show owe a small sample of cells on a microscope slide responded to the addition of 0. 03% Alcott blue dye, 7. 5 run EST., 0. 14 run A23187 in 1% DMS, 50 run caffeine, and 25 mm magnesium chloride (Magic). The data were obtained by viewing cells under a microscope; the cells were counted prior to treatment and the number of cells secreting trichinosis was counted after treatment.

Paleolithic

Our class will be going outside to try to help us understand Paleolithic times. We will experience the world as Paleolithic people did – bringing only what we can carry, having no permanent shelters, creating our own art from the materials around us and having to figure out the best place to stay. For this activity, we will assume that you are traveling in a small family group that Is part of a larger group of 31. You can be with either two other people or work with a partner, representing the core family group. It was typical of Paleolithic times that related core family groups would join together o form a larger group.This â€Å"family† would work together to gather food and protect each other. The group was usually between 15 and 30 people, though smaller and larger groups existed. As they traveled, different family groups would meet to exchange goods that they had made and they likely shared Information about the local environment. Young people likely moved between groups in order to share expertise (a group with several artists might exchange an artist for a skilled hunter) or to meet the needs of both groups (a group with extra males may send some to another group in exchange for goods or services).Over time, the larger group size allowed for some specialized roles to develop. The majority of people in the group would supply food for everyone, giving some people free time. For instance, a religious leader, artist or expert craftsman might supply the group's spiritual or technological needs rather than hunting or parenting. Women could take on a leadership role in the group. Women who gathered plants and hunted for small animals in many cases supplied most of the food for the group. In their role as mothers, they were protected from the most dangerous tasks, such as hunting or participating In battles with enemies.Instead, these types of tasks would be left to the â€Å"extra† males (the young and unattached men who were not yet In re ligious, artistic or craftsmen roles). Your task is to imagine yourself as part of Paleolithic times and to complete the following tasks. Your teacher will check that you are done at least Number 1 and Number 2 before the end of the period: 1. Use the map you have been given to decide where you will camp and have at least one person in your core family group record your reasons in the space provided. Consider the wants and needs of your group in addition to the geography of the area n your decision. . Using the tarp, sucks, butter knife and string, create a stable shelter. It will be 3. Using the modeling clay (which we are pretending is natural clay or soft stone), carve a Paleolithic figure and place it at the door of your shelter. 4. As a group or pair, explain what you think the daily life of Paleolithic people might have been like by creating a daily timeline to explain what your family would do at your campsite between the time you woke up and the time you went to sleep. Try t o include the challenges you faced today, such as weather, teamwork, etc. In your experience.

An Evaluation of the Myers Briggs Type Indicator

An Evaluation of the Myers Briggs Type Indicator The Myers-Briggs Type Indicator (MBTI) is a psychological test that was originally designed in the early 1940s by a mother-daughter team of Isabel Myers and Katherine Briggs. Myers and Briggs developed their test in response to the calamity of World War II, because they believed the war was caused by the countries involved failing to understand each other’s differences (Coe, 1992). The MBTI is designed to measure personality, and the basis for this test comes from the work of personality types as described by Carl Jung’s theory. All the information provided in this evaluation comes from form M of the MBTI. Purpose, Design and Format of the MBTI The purpose of the MBTI is to classify individuals on each of the four levels as identified in Jung’s theory, and then provide them with a description of their personality as a result of their test (Fleenor, 2001). On each of the four levels to identify a person there are two options on each level making a total of eight different possibilities that can be used to describe someone’s personality. Those levels are: Extraversion v. Introversion, Sensing v. Intuition, Thinking v. Feeling, and Judging v. Perceiving. As defined for the MBTI Extraverts enjoy communication with others and thrive off that contact; while Introverts tend to not find any pleasure in their relationships and prefer to be alone. Sensors use their five senses to gather information about a scenario and see the present for what it is; in contrast people scoring high in Intuition like to look toward the future and the possibilities that could exist. Finally, Judgers use the information available and come to a decision quickly; whereas Perceivers tend to be procrastinators and are always waiting for more facts before deciding (Coe, 1992). It is important to note that while the MBTI places test takers in a category of having one trait or the other that people do display characteristics of all eight, but tend to display one aspect on each level more prominently. The degree to which a person varies on a particular attributed is explained upon completion of the test. The questions on the MBTI are also designed in such a way that it is impossible to fall in the exact middle of a particular trait, everyone will vary slightly one direction or another (Fleenor, 2001). This test is designed for the general population ages 14 and older, and there is not a specific group who is not eligible to take the MBTI. This is considered a weakness by many and will be covered later. There are 93 multiple choice items on the MBTI, and the questions are written at a seventh grade reading level to ensure comprehension of the questions (Fleenor, 2001). Each question is designed so that one question is measuring just one type of personality level for simple and accurate scoring. In defining the norms for this test a group of 3009 people were administered the MBTI all were adults from the United States and were 18 years and older. Th e specific demographics of the normative sample are not given, but the sample was lopsided towards females and Caucasians (Fleenor, 2001).

The essential factors in the achievement of organizational goals Essay

The essential factors in the achievement of organizational goals - Essay Example It's My Bike recounted the experience of Debbie Martin as the new Supplier Quality Manager for the commercial product division of Cold Air Corporation. In this new position, Debbie encountered problems in the organization where a $250 bike is primarily involved. The bike was purchased by her predecessor and was currently utilized by her subordinate, Ronnie in order to inspect the incoming inputs in the plant's production line. As the company changed the supplier for one of its components, Ronnie's inspection became more frequent which consequently led to more frequent use of the bike. However, Cold Air Corporation is also currently undergoing a product transition handled by the Airhandler Quality managed by Steve Gregg. Because the distance from the Airhandler's office and the components for the new production line necessitated the use of the bike, Gregg borrowed the bike for his team's activities. This became the highlight of the case as Ronnie was quite hesitant in lending the bike to the other department while Airhandler Quality team argued that they are currently handling the most important project in the plant so they should take possession of the bike and Debbie should buy a new one. This paper will take a look at three problems encountered in... What seems to be one of the major causes of the recent misunderstanding was the real purpose of the bike. It should be noted that the conflict have arisen because there seems to be a vague designation of the bike. It was stated in the case that the bike was purchased by Debbie's predecessor in order to "aid in transporting testing materials and small samples from one end of the plant to another." However, there seems to be an inefficient communication within the organization as to where the bike should be used for. This can be indicated by the following situations: 1. the bike has been taken and repainted by the metal works department without the knowledge of Debbie or anyone in her department; 2. the bike was borrowed by the Airhandler Quality team for their own purposes and refused to return it without Debbie's formal request; and 3. Steve Gregg wants the bike to be utilized for his department as he is handling the most important project in the plant which will necessitate Debbie to buy a new bike for Ronnie's inspection. At the start of the case, it was stated that Debbie's boss is "not an easy person to work for" since he expects his employees to have a "take charge attitude and avoid bothering him with trivial issues." Taking this into account, Debbie should try to resolve the problem at hand first before resorting to his immediate superior. It is seemingly wrong that Debbie should bother his supervisor due to a $250 bike if he had given them responsibility and accountability in solving "trivial" problems within their department. In order to solve the conflict within the organization, Debbie should set the primary purpose which the bike will serve. As it was purchased by her

Australian organisations must adopt sustainability reporting in the 21 Essay

Australian organisations must adopt sustainability reporting in the 21 century - Essay Example However, the companies do not need to follow any standard reporting frameworks. Each industry faces varied external issues which are considered as significant to its operations (Hubbard, 2011). It can be stated that the companies are pressurised to disclose the non-financial information because of several market mechanism. These market drivers are found in numerous ethical, social as well as environmental investment funds that have given rise to sustainability reporting (Vormedal & Ruud, 2009). There are many reasons behind the companies’ disclosing sustainability reporting. They intend to persuade the non-stakeholders regarding the impacts of the performance of the company and strategies applied by it to stimulate the performance. The objective of sustainability reporting is to inform the shareholders regarding the fact that how well the company is handling with non-financial as well as financial risks. It also permits the company to recognize the areas of potential risks and evaluate its performance. Most of the companies prefer mandatory reporting since it sets up methods and structures for comprehending influences and risks which were not stated previously by the other organisations. It also offers institutional investors with the capability to avail the information on non-financial risks which further permits them to have better knowledge regarding the overall firm. Transparency and accountability to the stakeholders is promoted when companies tend to disclose sustainability reporting (Kolk, 2004). According to the views of Kolk, the main reasons behind sustainability reporting are to increase a company’s capability to keep track of the developments against particular targets. It tends to help in the proper implementation of the environmental strategy. It is proper sustainability reporting that creates awareness regarding the environmental issues in the organisation. Most of the companies try to focus more upon the sustainability reporting since it

Hinduism Essay Example | Topics and Well Written Essays - 750 words - 1

Hinduism - Essay Example e answer to this question can be found in the book â€Å"God is Dead: Secularization in the West†, 2002, wherein Steve Bruce defines religion as â€Å"beliefs, actions and institutions predicated on the existence of entities with power of agency (that is gods) or impersonal powers or processes possessed of moral purpose (the Hindu notion of Karma), which can set the conditions of, or intervene in human affairs†. Thus Karma is an essential component of Steve Bruce’s definition of religion and moral purpose that unites all Hindus. For Hindus the central belief is the never ending cycle of birth and death that an individual has to go through in his earthly existence, till salvation through unification with the Almighty is attained. In these different phases of an existence an individual is likely to commit both good and bad deeds. Karma is the total effect of these good and bad actions, which is the determining factor of the destiny of the individual (Chaudhuri, C. N., 1979). Hinduism is an open religious philosophy that gives its followers to tolerate any other religious beliefs. There are many who believe that Hinduism is more a way of life than a religion. In short this implies that it is the cultural and societal influences of Hinduism that are more important than the rigid religious beliefs. This aspect of Hinduism becomes extremely valid for the sub-continent of India, where Hinduism originated. The region is one of the most densely populated regions of the world. This population is made up of diverse religions in varying proportions with Hindus being the dominant religious grouping by far. Hinduism has provided to beneficial factors for the region. In the first place it as extremely tolerant religion on the basis of its nature, and thus religious minorities by far have not been subjected to domination by the Hindus. On the contrary in India the minority religious groups are recipients of special benefits from the administration just because they a re a

Reflection Statement about Nursing School Essay Example | Topics and Well Written Essays - 500 words

Reflection Statement about Nursing School - Essay Example Accordingly, as I was perusing my nursing program, I was able to finish the prerequisites for CSUDH and graduated with honors from CSUF with a bachelor’s degree in Health Science. I understand that an FNP program is very demanding and requires lots of skills and concentration which is as a result of the Family Nurse Practitioner’s role of providing a wide range of preventive and acute health care services to individuals in a wide age group. However, based on my greatest personal strengths, I am confident that I can efficiently achieve my goal of being a Family Nurse Practitioner without any prior nursing experience. This is because, according to my knowledge and understanding of the medical occupation, I believe that the most important aspect of being a Registered Nurse is not the clinical experience they have but rather knowing how to work with patients and having the general knowledge of what it takes to be a patient. In fact, the only reason that could deter me from succeeding in this program is the probability of not finding a clinical preceptor soon enough for the next clinical rotation. However, I have taken certain steps that will guarantee my success in the program which includes finding my first rotation in a Family clinic that works as an urgent after hours with the MD as a preceptor. In addition, the clinic has more than 20 years of experience and in order to complete the required clinical hours, I plan on working as just part-time. I am a very hardworking person, which is evident from my GPA hence I strongly believe that I will manage to balance my academic and clinical demands of the FNP program with my employment and personal commitments. The reason why I chose to pursue my career as a Family Nurse Practitioner is so as to be able to provide individuals with seamless health care. In addition, it would also allow me to take on greater responsibilities and gain significant ground in the fight for patient autonomy thus  satisfying my ultimate goal of making a difference for patients.  Ã‚

The group recognises the fact that resources are scarce and therefore employs every possible measure to use the resources in the best possible

Global Warming Essay Example | Topics and Well Written Essays - 500 words - 147

Global Warming - Essay Example As the paper outlines global warming is related to the greenhouse effect, which is the course by which absorption and discharge of emissions of gases in the atmosphere warms the lower atmosphere and the surface of the globe. Global warming is as a result of reasons, which may be either natural or manmade. Natural causes are those that are created by nature, and are often related to the emission of methane gas. This is the case in the arctic tundra and wetlands. Methane, being a greenhouse gas, holds heat in the mesosphere. Another natural cause is the cycle of climate change that usually takes about 40,000 years. Human activities have been credited for the changes in climate as early as during the industrial revolution. Their activities lead to increased levels of greenhouse gases in the atmosphere. Pollution is the biggest problem and results from a number of activities, the main being burning of fossil fuels. These are fuels, resulting from organic matter such as oil and coal. The burning of fossil fuels emits carbon dioxide. The mining of oil and coal also allows methane gas to escape into the atmosphere. This is because methane gas exists naturally in the ground. An increase in the population has also been credited for global warming. As people settle in new areas they clear the vegetation that previously existed and cause deforestation. Plants are known to take in carbon dioxide and emit oxygen. Their clearance increases the amounts of carbon dioxide in the atmosphere. There are a number of effects resulting from global warming. Weather patterns are most affected by the climatic change.
