Balanced Diet Essay Example for Free

Balanced Diet Essay Maintaining a healthy balanced diet is important for maintaining optimal health throughout life. For women of childbearing age, good nutrition is important for preparing the body for the demands of pregnancy. During pregnancy, a woman’s macronutrient (energy) and micronutrient (e.g. vitamins, mineral) requirements increase, and it is even more important that she consumes food which will give her both the energy and the specific micronutrients which are essential for maintaining her and her growing baby’s health. For example, women require an additional 240 calories of energy per day in the second trimester and 452 calories per day in the third trimester of pregnancy to account for foetal growth. An additional 975 milligrams of iron is required in the course of the pregnancy to form foetal and additional maternal blood. While nutritional supplements can provide large quantities of particular micronutrients, a healthy balanced diet should form the basis of a woman’s nutritional intake. Good nutrition is most important immediately prior to conception and during the first 12 weeks of pregnancy (including the very early stages, when the woman is unaware she is pregnant). It is therefore important for women to maintain a healthy diet throughout their childbearing years, and particularly if they are planning to become pregnant.In addition to regular exercise, a healthy well balanced diet is essential for good health. Life or rather the quality of life you have is dependent on having good health. A well balanced diet would contain the three main groups of food as well as important vitamins and minerals. The first group of carbohydrates are found in foods such as bread, potatoes and rice. They are essentially energy giving foods which power the muscles and other tissues in our body. The next class of food is the proteins which form the solid part in all living cells. They are commonly found in milk, met and fish, and are necessary for the body to build new cells and repair old damaged ones. For this very reason growing children require a greater intake of the different kinds of proteins as compared to adults. Lastly we have fats which are also energy-living foods but do not give it up as quickly as carbohydrates because their molecular structure is designed to render them ideal as storage foods. As children are much more active than adults they use up more energy for their size and therefore require more energy giving foods such as  carbohydrates. To this end fats are unsuitable. Moreover too much of a fatty food intake at an early age may lead to a problem with obesity in later life. In adults fatty deposits on the walls of the blood vessels in the form of cholesterol may lead to all kinds of heart ailments. In addition to the foods above the body also needs small quantities of protective substances called vitamins and minerals. They are normally present in a sensible diet. For example vitamins A and D are found in some fatty foods. Vitamin D is important along with the mineral calcium, found in milk, for the formation of bones. Vitamin B is found in the husks of wheat or rice ad vitamin C in fresh fruits such as oranges and lemons. Important minerals such as potassium, zinc and iron are present in traces n most foods too.

THE IMMORAL PROPOSAL FOR THE CHANGE OF DRUG LAWS Essay -- Drugs

In the United States the use of illegal drugs is prohibited. If one uses or possesses any type of an illegal substance it is considered a criminal offense. One must know that 15 million Americans use drugs each month (Husak 7). There are various points of view that disagree and agree with this law. An advanced society must realize that the idea of any attempt to allow illegal drugs to be legalized, in any way in society, cannot be morally permissible; a sound minded person cannot allow more addiction in a drug infested country. For our purpose an advanced society is a large number of persons that are morally knowledgeable of human wellbeing. A drug, for our purpose, is described as any substance other than food which by its chemical nature affects the structure or function of the living organism. The idea of changing illegal substance laws started with drug legalization, which stretches back to the early decades of the 20th century, but the contemporary debate emerged in1988. Kurt L. Schmoke called for the debate on drug control and strategies. Schmokes’s argument was that for generations the United States has been pursuing policies of prosecution and repression that resulted in little more than overcrowded courts and prisons, increased profits for drug traffickers, and higher rates of addiction. There are two main view points on the changing of drug laws. One is the Prohibition view point which is against drug legalization. Prohibitionist believe that laws that are set in place are enough and that the legalization of drugs would further disrupt family structure and imply drug use to American youth that would lower perceptions of harms and risks, as well as failing to eliminate drug addiction.( Inciardi 20). The parallel v... ...n illegal substance must consider after addiction free choice is no longer free. The first few times an individual uses an addictive substance, but that choice disappears as addiction becomes an experienced reality (Inciardi 39). Work cited Heath, Samuel .

Electrochemistry experimen Essay

Introduction: Redox reactions are reactions where the oxidation states of the atoms change. The atoms are either oxidized or reduced, depending if they lose or gain electrons. Electrochemical cells are devices that cause a current from redox reactions. It is set up so that electrons lost from one of the reagents can travel to another reagent. This creates a voltage, which is also known as the electric potential difference. This voltage can be read if a high-resistance voltmeter or multimeter is connected to the circuit. Salt bridge is used to allow migration of ions between two electric cells to maintain neutrality of solutions. It is usually made up of a filter paper moistened with an inert solution or an inert solution/gelatine salt bridge to prevent oxidation of certain ions. This experiment is divided into 2 parts: part A and part B. Part A Objective: To investigate the effect of change in lead(II) ion concentration on the potential of the Pb2+(aq) |Pb(s) electrode Introduction: This experiment investigates the e. m. f. of the cell: Cu(s) |Cu2+(aq) |Pb2+(aq)|Pb(s). Keeping the ion concentration in the copper electrode system constant(1M) and varying the ion concentration in the lead electrode system, the effect of change in lead(II) ion concentration on the potential of electrode as well as the Kc of the above reaction can be found. Chemicals: Copper foil x1, lead foil x1, 1M Cu2+ solution, 0. 1M Pb2+ solution, saturated potassium nitrate solution Apparatus: 250 cm3 beakers, 50cm3 beakers multimeter, distilled water bottle, filter papers, electrical wires with electrode holders, forceps, 100ml volumetric flask,10ml pipette x2, dropper Procedure: 1. The 0. 1M, 0. 01M, 0. 001M, 0. 0001M Pb2+ solutions were prepared from 0. 1M Pb2+ solution by dilution(1 portion solution plus 10 portions water). 2. The copper and lead electrodes were cleaned with a sand paper. 3. The circuit was connected as the diagram below. 4. The e. m. f. was recorded when the data shown was stable. 5. The above steps(2-4) were repeated with 0. 01M, 0. 001M and 0. 0001M Pb2+ solutions. Safety precaution: Potassium nitrate solution: Contact with combustible material may lead to fire 1M Copper(II) sulphate solution: harmful and irritating to eyes and skin. –>Safety goggles should be worn. Experimental set-up Results: [Pb2+]/M log[Pb2+] E/V 0. 1 -1 0. 482 0. 01 -2 0. 502 0. 001 -3 0. 521 0. 0001 -4 0. 545 Graph of E against log [Pb2+]: Trend shown: Given the ion concentration in the copper electrode system constant, it is found that the potential of the cell drops as the lead(II) ion concentration increase. The electrode potential is inversely proportional to the ten folds of ion concentrations. Calculation: When the reaction Cu2+(aq) + Pb(s) –> Pb2+(aq) + Cu(s) achieves equilibrium, the net e. m. f. of the cell=0 volt. The equilibrium expression of this reaction is: Kc= [ Pb2+(aq)][ Cu(s)] /[Cu2+(aq)][ Pb(s)] The effective concentration of Pb(s)/ Cu(s) are independent of its amount present and can be considered as constant. This reduces the expression to Kc= [ Pb2+(aq)] /[Cu2+(aq)] = 1Ãâ€"1021 Conclusion The potential of the cell decreases ad the ion concentration of Pb2+ increases. Further Analysis: Using the Nernst equation: E=E? -0. 059/n log[ox]/[red], Take [Pb2+]=0. 1 M as an example, E=0. 47-0. 059/2 log(0. 1/1)=0. 4405(V) [Pb2+]/M log[Pb2+] E/V(calculated) E/V(measured) %difference 0. 1 -1 0. 4405 0. 482 9. 42% 0. 01 -2 0. 529 0. 502 5. 10%.0. 001 -3 0. 5585 0. 521 6. 71% 0. 0001 -4 0. 588 0. 545 7. 31% It is shown that difference is present between the calculated value and measured value. This may be because of different conditions, resistance of the multimeter or errors in preparation of various concentrations of solutions. Part B Objective: To find out the equilibrium constant by e. m. f. measurement Introduction: The equilibrium constant for the below reaction is found out: Ag+(aq) + Fe2+(aq) Fe3+ (aq) + Ag(s) By e. m. f. measurement on the cell Pt |Fe2+(aq), Fe3+(aq)|Ag+(aq)|Ag(s) Chemicals: 0. 1 M Fe3+ solution, 0. 2 M iron(II)sulphate, 0. 2M barium nitrate, 0. 4M silver nitrate, platinum electrode, silver electrode Apparatus: gelatine salt bridge, 250 cm3 beakers, 50cm3 beakers ,multimeter, distilled water bottle, electrical wires with electrode holders, forceps, 10ml pipette x2 Procedure: 1. Equal volumes of 0. 2M FeSO4 and 0. 2M Ba(NO3)2 were mixed and the precipitate was allowed to settle without disturbance. 2. Equal volumes of 0. 1M iron(II) nitrate solution obtained and the iron(III)nitrate solution were mixed. This was the Fe2+(aq)/Fe2+(aq) half-cell. 3. The 0. 4M, 0. 2M, 0. 1M, 0. 05M, 0.025M silver nitrate solutions were prepared from 0. 4M silver nitrate solution by dilution. 4. The silver electrode was cleaned with a sand paper. 5. The circuit was connected as the diagram below. 6. The e. m. f. was recorded when the data shown was stable. 7. The above steps (4-6) were repeated with 0. 2M, 0. 1M, 0. 05M, 0. 025M silver nitrate solutions. Safety Precaution: Silver nitrate: harmful and oxidizing; 1) Poisonous if swallowed or inhaled 2) Skin contact with silver nitrate solid or solutions is likely to leave silver stains on the skin. Barium nitrate is poisonous and very harmful if swallowed. It is also a strong oxidizer, so may be hazardous if mixed with flammable materials. Experimental Set-upResults: [Ag+]/M log[Ag+] E/V 0. 4 -0. 398 0. 023 0. 2 -0. 699 0. 005 0. 1 -1 -0. 030 0. 05 -1. 301 -0. 050 0. 025 -0. 025 -0. 053 Graph of E against log[Ag+(aq)]: Calculation: When the reaction reaches equilibrium, both forward and backward reactions proceed to the same extent. This means that both the half cell reactions would have the same potential to proceed, so that the net e. m. f of the cell =0 volt at equilibrium. From the graph, the x-intercept is log[Ag+(aq)]=-0.72, hence,[Ag+(aq)]eqm=0. 1905 Ag+(aq) + Fe2+(aq) Fe3+ (aq) + Ag(s) KC= [Fe3+ (aq)]/ [Ag+(aq)][ Fe2+(aq)] =0. 1/ (0. 1905X0. 1) =5. 2493(mol2dm-6) ~5. 25(mol2dm-6) Conclusion: The equilibrium constant for the reaction between Fe2+/Fe3+ and Ag+ is 5. 25 mol2dm-6. Discussion(for both parts): 1. Possible Errors: -The electrodes (Cu(s),Pb(s),Ag(s)) were not cleaned very well with a sand paper so that they are not conducting electricity in all parts. The e. m. f. measured may hence be underestimated. -The same ammonium nitrate/gelatine salt bridge was used several times in part II of experiment. Ions of previous measurement may remain in the salt bridge and change the concentration of ions in the next measurement. -The apparatus including pipettes, beakers and volumetric flask may not be washed to be very clean. The error in concentration may be enormous when handling very dilute solutions (e. g. 0. 001M, 0. 0001M, 0. 025M) -The electrode touched the salt bridge once so that the accuracy of measurement of e. m. f. was affected. The solution is not exactly passed. -Air gap may be present in the ammonium nitrate/ gelatine salt bridge, increasing the resistance of ion migration. 2. Difference in effect of ion concentration on electrical potential of cell: -In part A, the cell e. m. f. increases as [Pb2+(aq)] decreases. However, in part B, the e. m. f. drops as [Ag+(aq)]. This suggests that when the species is a stronger oxidizing agent in the reaction and undergoes reduction, the presence of its ions tends to increase the e. m. f. whereas the one which undergoes oxidation tends to reduce the e. m. f. The species with more positive standard reduction potential has a positive effect but the one with less positive potential has a negative effect.

Children Living in Poverty Andrea Guzmà ¡n California State University, Fullerton I. NEEDS STATEMENT Children who live in extreme poverty or who live below the poverty line for multiple years appear, all other things being equal, to suffer the worst outcomes Income poverty is the condition of not having enough income to meet basic needs for food, clothing, and shelter. Because children are dependent on others, they enter or avoid poverty by virtue of their family s economic circumstances. Children cannot alter family conditions by themselves, at least until they approach adulthood (Brooks-Gunn Duncan, 1997). A child living in poverty is a societal issue that affects society as a whole. A. Nature and extent of the problem Data broken down by demographics, such as gender, ethnicity, region, age, specific distinctions within the population, prevalence, number of people National The statistics of children living in poverty are at elevated quantities.
