GCSE Chemistry

• carbon dioxide
• methane
• nitrogen
• ammonia
• oxygen

ammino acids which are the building blocks of proteins

No because it only shows how some of the molecules needed for life may have been formed

• that billions of years ago , the earths atmopshere was rich in carbon dioxide methane nitrogen ammonia and oxygen
• lightening struch causing a chemical reaction between the gases , resulting in the formation of amino acids
• the amino acids collected in a primordial soup - a body of water out of which life gradually crawled 
• the amino acids gradually combined to produce organic matter which eventually evolved into simple living organisms

they fired an electric spark , representing lightening at a mixture of gases including  carbon dioxide methane nitrogen ammonia and oxygen representing some of the gases present in the earths early atmopshere and water representing the oceans . A mixture of chemicals formed including amino acids . This is sometimes called a primordial soup meaning a rich mixture of chemicals essential for life 

• orange peel and water heated until it boils
• water and oil vapourise
• the distillate cools and condenses
• oil and water seperate due to differeny densities
• oil is decanted  

• seeds are harvested
• seeds are crushed
• water is added to the crushed seeds
• the mixture is pressed
• water and sunflower are obtained
• water and the sunflower oil seperate into two layers
• water and other impurities removed
• sunflower oil is collected
