Which is the more viable energy source for Australia’s energy and needs‚ Wind or Solar? This is a common debatable topic within the Federal Government of Australia. Debating which specific form of energy should be invested heavily in‚ in hope that carbon emissions and the use of coal will be reduced in the future (Clean Line‚ 2013). It is believed that the dominance of coal will be challenged by renewable energy e.g. Wind and Solar. Renewable energy is fast‚ clean‚ affordable‚ efficient‚ reliable

who need permanent families while Webber argues children of non heterosexual couples are more likely to be teased and sensitive to being harassed. Creating a family is not always simple. Today infertility is becoming more common. For some it may only take a few weeks to conceive‚ yet others it takes years and for some it may not ever be possible. Mallon extends on this thought a little‚ “For many lesbians and gay men‚ foster care or adoption is not a second choice‚ as it may be for heterosexual

Proteins provide our bodies with the amino acids that cannot be produced within the body. Through the process of digestion‚ food is broken down into essential amino acids that can be used for protein synthesis. In essence‚ proteins build up‚ maintain‚ and replace tissues in your body. For instance‚ proteins help make hemoglobin which carries oxygen to all the parts of your body. Proteins are broken down into amino acids during digestion. The amino acids can then be reused when the body needs protein

Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes
