Proteins Made From Ribosomes Attached To The Rough Endoplasmic Reticul

Proteins made from ribosomes attached to the rough endoplasmic reticulum enter the lumen of the ER and move to the smooth endoplasmic reticulum. A small vacuole (vesicle) pinches off the smooth ER and carries the protein to the Golgi apparatus, where it is further processed. ------------------------------------------------------------- Mitochondria are bounded by a double membrane. The inner membrane is folded to form little shelves, called cristae, which project into the matrix, an inner space filled with a gel-like fluid. -------------------------------------------------------------- A vacuole is a large membrane-enclosed sac that usually functions as a storage area. Plant vacuoles contain not only water, sugars, and salts but also pigments and toxic substances. The pigments are responsible for many of the red, blue, or purple colors of flowers and some leaves. ------------------------------------------------------------ The green pigment chlorophyll, found within the grana, makes chloroplasts and leaves green. Chlorophyll absorbs solar energy, and chloroplasts convert this energy into ATP molecules. ----------------------------------------------------------- Chloroplasts carry on the process of photosynthesis, in which light energy is used to produce food molecules, such as glucose. Chloroplasts take in carbon dioxide, water, and solar energy in order to produce glucose and oxygen. ------------------------------------------------------------ The energy-related organelles, chloroplasts and mitochondria, convert one form of energy into another. While chloroplasts are unique to plant cells, mitochondria are found in both plant and animal cells. ------------------------------------------------------------- Chloroplasts carry on photosynthesis, during which light energy (photo) is used to produce food molecules, like glucose (synthesis). Chloroplasts take in carbon dioxide, water, and solar energy in order to produce glucose and give off oxygen. ----------------- ------------------------------------------- Mitochondria are often called the powerhouses of the cell: just as a powerhouse burns fuel to produce electricity, the mitochondria convert the chemical energy of glucose products into the chemical energy of ATP molecules. -------------------------------------------------------------- Chromatin, a threadlike material, contains DNA and is found within the nucleus. At the time of cell division, chromatin condenses into rodlike structures called chromosomes. ---------------------------------------------------------- The middle lamellae, a region between cell walls, contains a sticky substance, usually pectin. Lignin is a substance found in secondary cell walls that makes them even stronger than primary cell walls. ------------------------------------------------------------ Autodigestion is important during development. For example, when a tadpole becomes a frog, the enzymes within lysosomes digest the cells of the tail, and the fingers of a human embryo are at first webbed, but they are freed from one another by lysosomal action. ------------------------------------------------------------- Lysosomes, vesicles formed by the Golgi apparatus, contain hydrolytic enzymes that can digest macromolecules. Macromolecules are sometimes brought into a cell in vesicles formed at the cell membrane. A lysosome can fuse with such a vesicle and digest its contents into simpler molecules, which then enter the cytoplasm. ------------------------------------------------------------- Special vacuoles (membrane-enclosed sacs) called peroxisomes are often attached to smooth ER, and these contain enzymes capable of detoxifying drugs. ------------------------------------------------------- A chloroplast is bounded by a double membrane. Inside the structure, there is even more membrane organized into flattened sacs called thylakoids. The thylakoids are piled up like stacks of coins, and each stack is called a granum. There are membranous conn ections between the grana called lamellae. The fluid-filled space about the grana is called the stroma. ------------------------------------------------------------- Inside the chloroplast, there is membrane organized into flattened sacs called thylakoids. The thylakoids are piled up like stacks of coins, and each stack is called a granum. The fluid-filled space about the grana is called the stroma. ------------------------------------------------------------- The nucleus is a large organelle that has a nuclear envelope, chromatin and nucleoli. The nuclear envelope is a double membrane that keeps the contents of the nucleus separate from the cell's cytoplasm. Pores in the nuclear envelope allow large molecules to pass into and out of the nucleoplasm, the fluid interior of the nucleus. ------------------------------------------------------------- Ribosomes are the site of protein synthesis in the cytoplasm. They can be attached to the endoplasmic reticulum or lie free within the cyto plasm. When several ribosomes are making the same protein, they are arranged in a functional group called a polysome. ------------------------------------------------------------ Both plant and animal cells have cell membranes, nuclear membranes, mitochondria, and vacuoles. Chloroplasts are found in plant cells but not in animal cells. ---------------------------------------------------------- All plants have a cell wall, located outside the cell membrane.

The Randle Report essays The Randle Report, by Kevin D. Randle explores UFO research in the1990's. In reading his book I have gained much knowledge of how to determine whether information submitted as proof of extraterrestrial existence is valid or bogus, and the truth (from a scientificstandpoint) about several famous unidentified phenomenoms. Much information is submitted to substantiate extraterrestrial existence. This information comes in many forms but the most common are: video, photography, and sworn testimony. Once this information is introduced UFO researchers have to test the authenticity of the information. In 1995 aman named Ray Santilli claimed to have authentic footage of the allegedRoswell alien autopsy. Although it was very interesting, it was most definitly a hoax. This conclusion came after the data from many tests (performed by unbiased scientists and experts in their respected fields) showed that many things in the film and the actual film did not correlateas they should have. In the film there were instruments that hadnt been invented yet and the film was unlike any from that time period. We as humans have always had a facination with visual displays. In 1987 Ed Walters produced several polaroid photographs, several of which were published in several national newspapers and magazines. Once again these photographs were very appealing to the American public but were proved to be not generic either.

Argument Against the Person - Argumentum ad hominem

Argument Against the Person - Argumentum ad hominem The ad hominem fallacy is a class of fallacies which is not only common but also commonly misunderstood. Many people assume that any personal attack is an ad hominem argument, but that isnt true. Some attacks arent ad hominem fallacies, and some ad hominem fallacies arent clear insults. What the concept argument​ ad hominem means is argument to the man, although it is also translated as argument against the man. Instead of criticizing what a person says and the arguments they are offering, what we have instead is a criticism of where the arguments are coming from (the person). This is not necessarily relevant to the validity of what is said - thus, it is a Fallacy of Relevance. The general form this argument takes is: 1. There is something objectionable about person X. Therefore, person Xs claim is false. Types of Ad Hominem Fallacy This fallacy can be separated into five different types: Abusive ad hominem: The most common and well-known type of ad hominem fallacy is just a simple insult and is called the abusive ad hominem. It occurs when a person has given up attempting to persuade a person or an audience about the reasonableness of a position and is now resorting to mere personal attacks.Tu quoque (two wrongs dont make a right): An ad hominem fallacy which does not attack a person for random, unrelated things, but instead attacks them for some perceived fault in how they have presented their case is often called tu quoque, which means you too. It often occurs when a person is attacked for doing what they are arguing against.Circumstantial ad hominem: Dismissing an argument by attacking an entire class of people who presumably accept that argument is called the circumstantial ad hominem. The name is derived from the fact that it addresses the circumstances of those who hold the position in question.Genetic fallacy: Attacking the origins for the position someone is proposing instead of the person or the argument is called the genetic fallacy because it is based on the idea that the original source of an idea is a sound basis for evaluating its truth or reasonableness. Poisoning the well: A preemptive attack on a person which questions their character is called poisoning the well and is an attempt to make the target appear bad before they even have a chance to say anything. All of these different types of ad hominem argument are fairly similar and in some cases can appear almost identical. Because this category involves fallacies of relevance, the ad hominem argument is a fallacy when the comments are directed against some aspect about a person which is irrelevant to the topic at hand. Valid Ad Hominem Arguments It is important, however, to remember that an argumentum ad hominem is not always a fallacy! Not everything about a person is irrelevant to every possible topic or any possible argument that they might make. Sometimes it is entirely legitimate to bring up a persons expertise in some subject as a reason to be skeptical, and perhaps even dismissive, of their opinions about it. For example: 2. George is not a biologist and has no training in biology. Therefore, his opinions about what is or is not possible with regards to evolutionary biology do not have a lot of credibility. The above argument rests upon the assumption that, if a person is going to make credible assertions about what is or is not possible for evolutionary biology, then they really should have some training in biology - preferably a degree and perhaps some practical experience. Now, to be fair pointing out the lack of training or knowledge does not qualify as an automatic reason for declaring their opinion to be false. If nothing else, its at least possible that they have made a guess by random chance. When contrasted with the conclusions offered by a person who does have relevant training and knowledge, however, we have a sound basis for not accepting the first persons statements. This type of valid ad hominem argument is therefore in some ways the reverse of a valid appeal to authority argument.

Interpretative Phenomenological Approach Essay Example | Topics and Well Written Essays - 1750 words

Interpretative Phenomenological Approach - Essay Example They found that interactive environmental activities in an outdoor programme had a significant impact on attitudes and that passive instruction had little impact on retention of knowledge. A scale of this type consists of a series of bipolar adjective pairs (e.g. good-bad, beneficial-harmful) listed on opposite sides of a page, with seven spaces in between. The attitude object is identified at the top of the scale and may be a word, statement or picture. The respondent is instructed to evaluate the attitude object by placing a mark in one of the seven spaces between each adjective pair. Development of semantic differential scales stems from the use of theory of reasoned action to investigate science-related attitudes. This is particularly important in the field of Psychology education where behaviour is a clear objective. In their theory, suggest that attitude measures should focus on a person's attitude toward behaviour rather than on the person's attitude toward particular objects. That is, instead of asking about students' attitudes towards the r researchers should assess their attitudes toward learning about the experience. This method is called the Interpretative Phenomenological Method, which is the approach used in this study in analysing the experience of Zoe, a teenager who has been adopted by a family. Interpretative Phenomenological Approach is a method which is considered as consonant with the picture presented above is introduced. Interpretative phenomenological analysis is a method which attempts to tap into a natural propensity for self-reflection on the part of participants (Abraham and Sheeran, 2001). Obviously the degree to which individuals are used to expressing such reflections, orally or in writing, can vary and some people need more encouraging and facilitating than others. But a central premise of the method is allowing participants to tell their own story, in their own words, about the topic under investigation. However, research is not a simple, singular process and the original account from the participant in the form of an interview transcript or diary entry, for example, then needs to be analysed closely by the investigator. Interpretative phenomenological analysis is about attempting to discover meanings, not eliciting facts, but trying to find out what a person's health condition means to them requires considerable interpretative work on the part of the researcher (Abramson et al., 2003). The resultant analytic account can therefore be said to be the joint product of the reflection by both participant and researcher. This study will provide a brief theoretical contextualisation for interpretative phenomenological analysis and then argues for the particular relevance it has for health psychology. It is worth pointing out that this approach aims to have a dialogue with, and to help enlarge, the discipline of psychology not to attack or stand outside it. As will become apparent, interpretative phenomenological analysis can make a valuable contribution in enriching the way mainstream psychology conceives of the individual's experience of adoption. Method The interpretative phenomenological analysis applied to the social psychology as an application to the study on the experience of the subject Zoe as an adopted in a family. The first example is from a study examining how Zoe feels of him being adopted. The project involves analysis of long semi-structured interviews with Zoe. Because the study is

The Missing Link in Conflict resolution Essay Example | Topics and Well Written Essays - 2250 words

The Missing Link in Conflict resolution - Essay Example IGD also aims to identify differences across the groups brought together and to improve the capabilities of both individuals and groups to achieve social justice (Nagada and Gurin 2007, 35). This paper compares and contrast the conflict processes operative for Northern Ireland, South Africa and the Israeli/Palestinian conflicts. The object is to identify what if any of the IGD theories are reflecting in these three conflict resolution process. The South African Truth and Reconciliation Commission (TRC) is characterized as among the country’s â€Å"most effective† conflict resolution processes to date (Gibson 2006, 409). The TRC has contributed significantly to South Africa’s democratic reforms by influencing a â€Å"more reconciled society† (Gibson 2006, 409). The conflict resolution process in Northern Ireland takes a similar holistic approach in that the conflict resolution process is centered around policies and initiatives designed to foster equality and to â€Å"improve community relations† (Cairsn and Darby 1998, 754). The School of Peace approach to the Israeli/Palestinian conflict resolution is slightly different in that the process aims to heighten individual awareness of the conflict, their part in it and the facilitation of identities via intergroup interactions (Halabi and Sonnenschein 2004, 49). IGDs are built around bringing together between 12 and 16 students once a week for between ten and fourteen weeks. These students convene under the leadership of a â€Å"trained peer† who instructs from a plan that merges several learning initiatives which include â€Å"intellectual and effective engagement†; â€Å"individual reflection and group dialogue†; â€Å"individual intergroup and institutional analyses†; â€Å"affinity-based and heterogeneous groupings;† and â€Å"individual and collective action† (Nagada and Durin 2007, 35). IGD takes the position that the social justice education typically fails to implement tools of intergroup interactions
