Osmosis in Quails’ Egg Essay

Title:Osmosis in quails’ egg Aim: To observe the effect of different concentrations of sodium chloride on a de-shelled quail’s egg To explain the effects in terms of osmosis Research Questions: Does the different concentrations of sodium chloride on a de-shelled quail’s egg effect the final mass of quail’s eggs that is measured by using electronic weighing balance? Introduction: â€Å"If a cell is to perform its functions, it must maintain a steady state in the midst of an ever-changing environment. This constancy is maintained by the regulation of movement of materials into and out of the shell. To achieve this control, cells are bounded by a delicate membrane that differentiates between different substances, slowing down the movement of some while allowing others to pass through. Since not all substances penetrate the membrane equally well, the membrane is said to be differentially permeable. The external and internal environment of cells is an aqueous solution of dissolved inorganic and organic molecules. Movement of these molecules, both in the solution and through the cell membrane, involves a physical process called diffusion – a spontaneous process by which molecules move from a region in which they are highly concentrated to a region in which their concentration is lower. A special kind of diffusion is the phenomenon of osmosis. Simply defined in biological systems, osmosis is the diffusion of water through a differentially permeable membrane from a region in which it is highly concentrated to a region in which its concentration is lower. ;

Nursing and American Nurses Association Essay

Describe the definition of nursing as put forward by the American Nurses Association. How does it address the metaparadigm theories of nursing? According to the American Nurses Association (ANA), the definition of nursing is â€Å"the protection, promotion, and optimization of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations.† Metaparadigm theories of nursing consists of theories that describe the four interrelated concepts, which are persons, environment, health and illness, and nursing. Persons are the recipients of nursing care and include individuals, families, and communities. Environment refers to the surroundings of the client, internal factors affecting the client, and the setting where nursing care is delivered. Health and illness describe the client’s state of well-being. Nursing refers to the actions taken when providing care to a patient. ANA’s definition of nursing has included three of the four concepts that make up the metaparadigm theories of nursing. Its definition strongly emphasizes the concept of nursing. It listed many functions that nurses perform such as: protecting, promoting, optimization of health and physical abilities, preventing illness and injury, alleviating suffering, and advocating for patients (ANA website, n.d.). All these nursing actions are related to the care of health and illness, which is the second concept of the metapardigm theories of nursing. The ANA’s definition of nursing describes in more detail the concept of health and illness in terms of health, abilities, illness, and injury. These physical conditions affect the state of well-being and may lead to one’s own suffering and negative responses (ANA website n.d.). Persons is the third concept. According to the ANA definition of nursing, persons include: individuals, families, communities, and populations that receive nursing care. The fourth concept is environment. It is directly related to the other three concepts mentioned above. The environment is the surroundings or the settings in which nursing care is delivered and includes the in the hospital, home, theater, etc†¦

Common Problems for an Extended War and the Solutions Essay

Neither the North nor the South had prepared for an extended war. Two years into the conflict, both faced common difficulties. Foremost was the lack of money and manpower. The war was expensive and both treasuries were depleted. While neither initially wanted to impose direct taxes to finance the war, they were forced by circumstances to turn to taxation though on a small-scale. The North seemed to have had more success in raising funds. With the North’s population greater than that of the South, the new tax was able to finance 21% of the war expenses while it was only 1% for the South. Both also tried borrowing. The North being more committed to the idea and was able to obtain more than $2 billion worth of bonds in loan. Another solution that was considered and eventually enforced was the printing of paper money. The Confederacy started with $100 million while the Union printed $150 million worth of â€Å"greenbacks† so called because of its color. The flooding of paper money expectedly led to inflation that resulted to food prices increasing to 80%. This led to hardships in the urban areas which were unable to produce their own food. Volunteers in the army for both sides dwindled off as disillusionment set in. The prestige of army life with its military parades and victories were gone as the harsh realities of deadly diseases, camp life boredom, loss of values, impersonal destruction and conditions of being â€Å"half-starved, half-frozen and half-drowned† were experienced. There were also desertions. To entice would-be soldiers, sign-up bonuses of $800 to $1000 were given to outsiders. Soon, they resorted to the draft despite anticipated opposition and anger by the general populace. However, instead of forcing men to serve, they encouraged those who are already in the army to re-enlist and attract volunteers. The South needed more of these draftees since the North had about 180,000 able immigrants to choose from. The allowance for substitution and exemption, however, led to even further resentments as the conditions clearly favored the rich.

The American welfare program encourages abuse and Entitlement Research Paper

The American welfare program encourages abuse and Entitlement - Research Paper Example The welfare program in the U.S. encourages abuse and entitlement by altering the resilient attitude of vulnerable groups. â€Å"Members of vulnerable populations have often displayed remarkable resilience and ingenuity in addressing their own needs† (Jansson 5). In low income communities, informal support systems are usually in place. Neighbors and church members help each other. For some groups, demand for welfare services is even lower. â€Å"Foreigners have lower health expenditures than native-born Americans and contribute more to the economy, both in productivity and taxes, than the public service they may receive† (Viladrich 825). When welfare programs broadly target certain groups without considering particular needs for purposes of determining eligibility, the attitude of resilience can shift to dependence. â€Å"In a welfare state context, multiculturalism may not be beneficial for immigrants at all, because it may lead to dependence on welfare-state arrangeme nts and thereby to social and economic marginalization†. Dependence can lead to abuse. The American welfare program encourages abuse and entitlement in not addressing social barriers to employment. Welfare recipients commonly face â€Å"low or few job skills, low educational attainment, lack of jobs in the community, and problems with transportation as barriers to finding and sustaining employment† ... When social welfare acts as a buffer for low income families without being linked to empowerment, this encourages dependent attitudes that breed abuse.
