The Benefits of Organic Food—Draft #1 Organic food‚ once only found in health food stores‚ is now a consistent element at local supermarkets. So what is the difference between a conventionally grown apple and an organic one? The answer is in the way the crop is grown and what it is and is not exposed to. In order to be labeled “organic” the farmer who grew it used renewable resources and conservation of soil and water methods. Also‚ organic farmers do not use conventional pesticides or weed killers

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure of the compound. The effect of the solvent polarity and temperature will also be looked at. Name Structure M.W. M.P.

submitted. APA offered rigorous psychological evidence emphasizing the major impact stigma has on well-being‚ the benefits of marriage‚ and the lack of difference between lesbian and gay parents and heterosexual parents. According to the brief: 1. Homosexuality is neither a disorder nor a disease‚ but rather a normal variant of human sexual orientation. The vast majority of social prejudice‚ discrimination and violence against lesbians‚ gay men and bisexuals takes a cumulative toll on the well-being
