Types Of Cells Essay Example for Free

Types Of Cells Essay Select two structures of bacterial cells and briefly describe them; what do they look like, what are they composed of? Then, explain how these two structures allow bacterial cells to survive as unicellular organisms.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Two structures of bacterial cells are the cytoplasmic membrane and the flagella. The cytoplasmic membrane is mainly composed of two phospholipids layers or phospholipids bilayer (University of South Carolina, 2007).   It primarily acts as a selectively permeable barrier for a lot of molecules and also serves as a transport location of these molecules into the cell. In addition, the cytoplasmic membrane of bacteria also conserves energy as it also the location where motive forces are created for use (University of South Carolina, 2007). Basically, like any other cell membrane, a bacterial cytoplasmic membrane mostly contains lipids and proteins and other biological molecules that serve as the bacteria’s energy and life source (University of Wisconsin, 2008). Most bacterial cell membranes also contain hopanoids which function primarily to improve the fluidity of the plasma membrane by modulating its fatty acids. It can also play an important role in adjusting the permeability of the cell membrane and increasing the adaptability to extreme conditions (University of Wisconsin, 2008). Another important bacterial cell structure is the flagella. The flagella are filamentous structures which are attached to the surface of the cell that provide movement for most of the motile bacteria. They are mainly composed of protein and appear as whips or threads that extend from the body of the bacteria. In other words, they allow the bacteria to swim around while inside another organism. The cytoplasmic membrane and the flagella are two structures that are highly essential to the bacteria as it provides them to adapt and survive in most environments. The cytoplasmic membrane transports solutes such as nutrients and other molecules that enable the bacteria to live. It also serves as the location for the generation of energy or ATP which is important to any organism. The flagella, on the other hand, allow movement, which is important for a lot of bacteria, as it enables them to survive by moving around and infecting the host. Choose either a plant or an animal cell. Choose two structures or organelles of the cell (not used in part one above.) Describe these two structures or organelles – what do they look like, what are they composed of? Then explain how these plant or animal cell structures or organelles function. How do these functions support activities of the plant or animal cell and enable survival of the multicellular plant or animal organism?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Two important organelles of plant cells are the chloroplast and the endoplasmic reticulum. Chloroplasts is possibly one of the most vital organelles found in a plant as it conducts photosynthesis, which his the ability of plants to manufacture their own food using light (Molecular Expressions, 2005). It is the chloroplasts that absorb the light and use it together with carbon dioxide and water to produce sugars, which are the material that the plant uses for food. Morphologically, they appear as flat discs (Molecular Expressions, 2005).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The endoplasmic reticulum, on the other hand, appears as a network of tiny sacs such as cisternae, vesicles, and tubules. This network of structures mainly functions to manufacture, produce, transport, and process chemical compounds that will be used outside and inside the cell (Molecular Expressions, 2005). Basically, the chloroplast and the endoplasmic reticulum are very important organelles that ensure the plant’s survival. The chloroplast facilitate the manufacturing of the plant’s food source, which is important for any living organism, and the endoplasmic reticulum transports the energy sources as well as other chemical compounds that enable the plant to live.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   References Molecular Expressions.

The Boston Massacre and Other Contributing Factors of the Revolutionary

The Boston Massacre and Other Contributing Factors of the Revolutionary War The Boston Massacre was not the only cause of the Revolutionary War. There were many events before and after that also contributed to the start of this war. They were the Sugar Act, Stamp Act, Declaratory Act, Townshend Act, Quartering Act, Tea Act, the Boston Tea Party, and Coercive Acts. One of the first taxes put on the colonies by Britain was the Sugar Act. The Sugar Act of 1764 was to raise money to help Parliament run the colonies. This act put a tax on goods such as molasses, coffee, and sugar. It also required shippers to have a detailed outline of their cargoes. Smugglers could also be tried in admiralty courts. If convicted, the offenders lost both the cargo and the ship that carried it. Most colonists believed they should only be taxed by a government they had elected. They did not like this taxation without representation. The Stamp Act was then passed to help raise money to run the colonies. The Stamp Act was passed by Parliament in March 1765. This Act taxed the use of printed materials such as deeds, marriage licenses, advertisements, newspapers, diplomas, customs documents and even playing cards. Many colonial assemblies were against this taxation and wrote petitions demanding the repeal of this act. The first open resistance were riots caused by the Sons of Liberty who believed in action rather than talk. So, Parliament repealed this Act and then passed the Declaratory Act The Declaratory Act was a statement of power. It said the colonists were under the control of Parliament and they could pass any law they wanted. This Act did not settle the issue of taxation without representation.

Performance Development Plan

IntroductionThis development plan will focus on the characteristics of my learning team as well as my personal characteristics as their leader. This plan will allow me to assess the needs of my learning team as well as the ability to hone in on their strengths, areas for improvement, and resources needed to help them reach their career goals. This development plan will also allow me to determine how my leadership style will impact the success of the team and give me the ability to adapt to different behavioral styles by reviewing each individual DISC Platinum Rule – Behavioral Style Assessment. Personal and Individual Team CharacteristicsPersonal CharacteristicsBased on the DISC Platinum Rule – Behavioral Style Assessment that both my learning team and I completed, we fall into three major categories – Interactive, Dominance, and lastly Cautious Styles. In my personal assessment I was categorized primarily as Interactive in style and traits. Based on this knowled ge my primary style includes persuading, motivating, and entertaining others; whereas the assessment states my growth areas include attention to detail, short attention span, and low follow-through. The main focus or priority for me is people and being interactive, busy, and personal in the workplace setting.Individual Team CharacteristicsTwo of the team members, besides me, were also characterized as Interactive – â€Å"The Impresser†. Some additional characteristics in this category include wanting to achieve results with flair, judging people by their ability to make things happen, working harder when bigger risks or rewards are at stake, prefer to share in work and goals with people, wanting to do things the ‘best’ way, and become restless, short-tempered, lashing out when under pressure.Two team members had the Dominance Style traits which include individuals being time-sensitive, organized, and to the point. The Dominance Style is driven by two gover ning needs: the need to control and the need to achieve. The D Styles are goal-oriented go-getters who are most comfortable when they are in charge of people and situations. They want to accomplish many things now, so they focus on no-nonsense approaches to bottom-line results.The Dominance Styles seek expedience and are not afraid to bend the rules. They figure it is easier to beg forgiveness than to ask permission. The D Styles accept challenges, take authority, and plunge headfirst into solving problems. They take charge in a crisis. They are fast-paced, task-oriented, and work quickly and impressively by themselves, which means they become annoyed with delays. They are willing to challenge outdated thinking and ideas.Lastly, one team member had the Cautious Style traits which include analytical, persistent, systematic people who enjoy problem solving. They are detail-oriented, which makes them more concerned with content than style. The C Styles are task-oriented people who enjo y perfecting processes and working toward tangible results. They are almost always in control of their emotions and may become uncomfortable around people who are very out-going, e. g. , the Interactive Styles. Strengths and Growth Opportunities of Behavioral Styles StrengthsInteractive Style leaders’ primary strengths are their enthusiasm, persuasiveness, and sociability. Dominance Style leaders’ primary strengths are accepting challenge, ability to take authority, and go head first into solving problems. They have an ability to get things done and their decision making skills are very high. Cautious Style leaders’ primary strengths are their accuracy, dependability, independence, follow-through and organization.Growth OpportunitiesGrowth Opportunities for the Interactive Style of Behavior are broken into two categories with tasks and with people. Interactive Styles tend to underestimate the time and effort required by themselves or others to accomplish tasks. They also tend to be impatient, primarily when they are stressed or under pressure. Growth opportunities for the Dominance Style of Behavior include being broadening their perspectives.They need to learn to be effective outside of their comfort zone by considering different points of view and other ways to achieve their goals. Growth opportunities for the Cautious Style of Behavior include being more attentive to details and timely follow-through. Curiosity of these leaders may lead to digressions while at work. These leaders are found to be intense by nature and tend to be impatient with themselves and others, especially when things aren't going well.Development Plan for Each Behavioral StyleDevelopment Plans for the Team based on Behavioral StyleInteractive Style Development PlanIn order for Interactive Style leaders to be successful they need to be more selective about tasks that they take on and not be afraid or hesitate to ask others for help. When dealing with others they need to learn how to relax and enjoy regular recreation to ensure that they can handle their reactions in a proper manner to stress. Delegating tasks instead of taking everything on, asking for assistance on projects while coaching staff, will allow them to grow in their organizations, while still feeling like they are in the know.Not only will this allow and them to focus on other opportunities they are developing their staff. In order to be successful in the work environment they need to prioritize, organize, see tasks through completion, and write things down. As their leader, I will show them that I admire their hard work and accomplishments, support their feelings when possible, interact with them, support their ideas and show them my positive side. Being that I am an Interactive Style leader this will come naturally to me in dealing with other leaders of this style in my group.Dominance Style Development PlanIn order for these leaders to be successful they need to consider viewpoi nts of others and look outside the box for other ways to achieve goals. These leaders would benefit from being flexible in their decisions and this would help them solve problems more creatively. This not only allows for the leader to grow, but also develops more trust in the associates they are leading. As their leader I can provide precise data on projects that they are working on, allow them to work independently and do things within their limits, look for opportunities to modify their work-load focus, and allow them to take the lead.Being that both this style and the Interactive style both preferring faster pace we will get along well with pacing the workflows. Cautious Style Development Plan For Cautious Style leaders to be successful they need to learn to pace themselves. Taking time-outs during the workday may help allay their natural intensity. They need to remain positive when dealing with situations and people under pressure. If they are able to control their thoughts and emotions in such cases, then they can use their creativity to discover workable solutions.These leaders will benefit from staying focused on key priorities, sorting out tasks, outline expectations for associates, and allow others to take control of projects. This will not only allow the leader to balance their growth opportunities but will also allow their associates to gain more trust in the leader. As their leader, when I approach them for questions or projects I will ask them in a direct manner, show reasoning, provide explanations in writing, compliment them on their thoroughness, and ask tactfully how I may assist them if needed.ConclusionIn conclusion, after reviewing each individual assessment of my learning group as well as my personal assessment through the DISC Platinum Rule Behavioral Style Assessment, I have been able to review how each Style has their own strengths and weaknesses, and how to create a professional performance plan on helping each team member to be succes sful in their organization. The assessment has allowed me to have a better understanding of different behavioral characteristics as well as my own personal traits, strengths, and weakness. This will give each of us the ability to balance, adapt, and grow in our roles within our organizations.

The Effects Of Mandatory Arrests On Domestic Violence Essay

Introduction With approximately 1.3 million women being victimized by an intimate partner each year and one in every four women experiencing domestic violence at some point in her life-time, domestic violence, also referred to as intimate partner violence Even after decades of increased activism and raised awareness by government agencies, the public and many nonprofit organizations, domestic violence still remains a serious problem within the United States. In order to combat domestic violence, many states passed laws and legislation requiring police to make warrantless arrests in response to all domestic violence calls. Harvard scholar, Radha Iyengar, who has studied domestic violence related homicide and the effects of mandatory arrest policies for domestic violence, suggests that although these policies were created to help victims, the solution of mandatory arrests in domestic violence incidents, led to many negative consequences; putting many women in danger, rather than helping them (Iyengar). Though designed to deter violence by offenders, mandatory arrest laws make women more vulnerable to being arrested themselves, lead abuse in domestic violence disputes to become more severe, and deter women from reporting violence to police (Strout). The mandatory arrest law, falling under the Violence Against Women Act (VAWA), though originally passed in 1994, has been reauthorized in 2000 and 2005. With the VAWA expiring in 2011, reauthorization of this act, including itsShow MoreRelatedMandatory Arrests For Domestic Violence1682 Words   |  7 PagesRunning head: MANDATORY ARRESTS 1 MANDATORY ARRESTS 8 Mandatory Arrests for Domestic Violence Do More Harm than Good Colby Heywood University of Massachusetts - Lowell Mandatory Arrests for Domestic Violence Do More Harm than Good Domestic violence, or intimate partner violence, is a common problem.
