- fermentation = ethanol produced isn't concentrated and purified
- polymers
- plastic bags, memory foam, tooth fillings
- plastic bags = polymers + corn starch
- plastic bags, memory foam, tooth fillings
- plant oils
- food and fuel
- fuels because of lots of energy e.g. biodiesel
- loads of energy and nutrition
- food and fuel
- fuels because of lots of energy e.g. biodiesel
- food and fuel
- food and fuel
- emulsions
- food, moisturisers etc
- hydrophilic head out, hydrophobic tail out - heads repel each other and prevent droplets from forming together
- increase shelf life as they stop emulsions separating
- risk of allergy e.e to egg
- plate tectonics
- fossils on separate continents, coastlines of africa and s america match, rocks with matching layers found, tropical plant fossils found in arctic
- wegener thought tidal forces and rotation of the earth were the cause
- thought imposible as the forces would have too be so great that they stopped the earth from turning
- wasn't believed - he wasn't a qualified geologist, he had used flawed data
- earths structure
- earthquake predicted by strain in rocks underground,low reliability
- volcanoes predicted by rising molten rock = bulge, low/medium reliability
- evolution of atmosphere
- -->earths surface is molten, atmosphere boils away -->earth cools slightly so crust is formed --> water vapour condenses to form oceans --> green plants and algae evolve over earth, CO2 dissolves in oceans -->complex organisms flourish and ozone layer formed -->4/5 N 1/5 O
- primordial soup = N2, H2 NH3 + CH4, lighting stuck causing reaction making amino acids, life crawled out of this primordial soup
- miller and urey sealed gases, heated them and applied electrical charge for a week
- amino acids were created but not as many as there are on earth - along the right lines but not quite right
- miller and urey sealed gases, heated them and applied electrical charge for a week
