1Fermentation is [blank_start]anaerobic[blank_end] [blank_start]respiration[blank_end] in [blank_start]yeast[blank_end].
- Aanaerobic
- Brespiration
- Cyeast
2What happens to the waste water that food - processing factories produce when they wash their equipment?
- AYeast is added to the water, as the water is contaminated with sugar and yeast is very efficient at breaking down sugar. The water can then be released into rivers
- BIt is contained and recycled in the factory to wash equipment
- CIt is transported into the ocean
3Wine is made from [blank_start]grapes[blank_end]
Beer is made from [blank_start]malted[blank_end] [blank_start]barley[blank_end]
Cider is made from [blank_start]apples[blank_end]- Agrapes
- Bmalted
- Cbarley
- Dapples
4Fermentation:
[blank_start]Sugar[blank_end] ------> [blank_start]ethanol[blank_end] ( [blank_start]alcohol[blank_end]) + [blank_start]Carbon[blank_end] [blank_start]Dioxide[blank_end]
C6H1206 ------> 2CH5OH + 2C02- ASugar
- Bethanol
- Calcohol
- DCarbon
- EDioxide
5Sometimes the carbon dioxide produced during fermentation is useful as it makes the drink naturally [blank_start]fizzy[blank_end]. If a [blank_start]fizzy[blank_end] drink is not wanted, the [blank_start]carbon[blank_end] [blank_start]dioxide[blank_end] is allowed to [blank_start]escape[blank_end] from the brewing tank.
- Afizzy
- Bfizzy
- Cescape
- Ddioxide
- Ecarbon
6Brewing Beer:
1.) [blank_start]Barley[blank_end] [blank_start]seeds[blank_end] are mixed with [blank_start]water[blank_end] and allowed to [blank_start]sprout[blank_end]. This turns the [blank_start]starch[blank_end] in the [blank_start]seeds[blank_end] into [blank_start]sugars[blank_end]
2.) '[blank_start]Mashing[blank_end]': [blank_start]Hot[blank_end] water is added to extract the [blank_start]sugar[blank_end].
3.) [blank_start]Hops[blank_end] are added to give [blank_start]flavour[blank_end]
4.) [blank_start]Yeast[blank_end] is added to ferment the [blank_start]sugars[blank_end] into [blank_start]alcohol[blank_end]. The mixture is kept [blank_start]warm[blank_end] to encourage the yeast to [blank_start]reproduce[blank_end] and res[blank_start]pire[blank_end].
5.) The tank is sealed to prevent air getting in to ensure the yeast respires [blank_start]anaerobically[blank_end]. This also stops unwanted [blank_start]microorganisms[blank_end] spoiling the beer.
6.) A [blank_start]chemical[blank_end] is added to make the yeast [blank_start]settle[blank_end], leaving a [blank_start]clear[blank_end] liquid.
7.) The beer is [blank_start]pasteurised[blank_end] to kill harmful [blank_start]microorganisms[blank_end]
8.) It is then bottle or put into sealed casks- ABarley

7The yeast is [blank_start]filtered[blank_end] out ( or killed by [blank_start]heat[blank_end] [blank_start]treatment[blank_end] ) [blank_start]before[blank_end] the beer is sealed in bottles. If the yeast was left in, it would continue to [blank_start]respire[blank_end] and produce [blank_start]carbon[blank_end] [blank_start]dioxide[blank_end], causing the beer bottles to [blank_start]explode[blank_end].
To [blank_start]pasteurise[blank_end] the beer, it is heated to [blank_start]72[blank_end] degrees for [blank_start]15[blank_end] seconds and then [blank_start]cooled[blank_end] quickly. This [blank_start]kills[blank_end] [blank_start]harmful[blank_end] microorganisms but doesn't affect the [blank_start]taste[blank_end] much. This needs to be done to bottled beers to prevent spoilage by [blank_start]microbes[blank_end].- Afiltered

8When yeast is used in fermentation, why must it be grown without oxygen?
- AIf oxygen is available, the yeast will respire aerobically and make only carbon dioxide and water
- BThe oxygen kills the yeast
- CYeast reproduces on a much larger scale in the absence of oxygen
9Distillation can be used to make the alcohol more [blank_start]concentrated[blank_end] and to produce [blank_start]spirits[blank_end]. It involves [blank_start]heating[blank_end] the liquid to [blank_start]evaporate[blank_end] the [blank_start]alcohol[blank_end], and then [blank_start]trapping[blank_end] and [blank_start]cooling[blank_end] the [blank_start]concentrated[blank_end] [blank_start]alcohol[blank_end] back into a liquid. Distillation can only be done on [blank_start]licensed[blank_end] premises. [blank_start]Spirits[blank_end] can be distilled from [blank_start]cane[blank_end] [blank_start]sugar[blank_end] ( rum ) , [blank_start]malted[blank_end] [blank_start]barley[blank_end] ( whisky ) and [blank_start]potatoes[blank_end] ( Vodka )

10The amount of alcohol in [blank_start]brewed[blank_end] drinks ( [blank_start]wine[blank_end] or beer ) is [blank_start]limited[blank_end] because the [blank_start]yeast[blank_end] are [blank_start]poisoned[blank_end] by the [blank_start]alcohol[blank_end] they [blank_start]produce[blank_end]. Some varieties of yeast have a greater [blank_start]tolerance[blank_end] to higher [blank_start]concentrations[blank_end] of [blank_start]alcohol[blank_end] and can be used to brew [blank_start]stronger[blank_end] beers.

11What does biogas contain?
- A60% methane
- B40% carbon dioixde
- C40% methane
- Dtraces of hydrogen, nitrogen and hydrogen sulfide gas
12Decomposer [blank_start]bacteria[blank_end] can be found in [blank_start]marshes[blank_end], [blank_start]septic[blank_end] [blank_start]tanks[blank_end] and inside [blank_start]animal[blank_end] [blank_start]digestive[blank_end] [blank_start]systems[blank_end]. When they feed on dead [blank_start]plant[blank_end] and [blank_start]animal[blank_end] material, they produce a mixture of [blank_start]waste[blank_end] [blank_start]gases[blank_end] called [blank_start]biogas[blank_end].

13The [blank_start]methane[blank_end] released from decomposing organic rubbish in [blank_start]landfill[blank_end] sites can catch [blank_start]fire[blank_end] or [blank_start]explode[blank_end]. Therefore, [blank_start]landfill[blank_end] sited cannot be [blank_start]built[blank_end] on for many [blank_start]years[blank_end].
- Amethane
- Blandfill
- Cfire
- Dexplode
- Elandfill
- Fbuilt
- Gyears
14Which of the following are true regarding biogas?
- ABiogas does not release as much energy as natural gas
- BBiogas that contains more than 50% methane it burns easily and makes a good fuel
- CBiogas that contains less than 10% methane is explosive (especially if mixed with oxygen)
- DBiogas is a cleaner fuel than petrol or diesel
- EBiogas releases more energy than natural gas
- FPetrol or diesel are cleaner fuels than biogas
15Biogas can be made on a [blank_start]large[blank_end] scale using a [blank_start]continuous[blank_end] - flow method in a [blank_start]digester[blank_end]. [blank_start]Organic[blank_end] [blank_start]material[blank_end] is added daily and the [blank_start]biogas[blank_end] is siphoned off and [blank_start]stored[blank_end]. The remaining [blank_start]solid[blank_end] [blank_start]sludge[blank_end] can be used as [blank_start]fertiliser[blank_end] for [blank_start]crops[blank_end]
- Alarge
- Bcontinuous
- Cdigester
- DOrganic
- Ematerial
- Fbiogas
- Gstored
- Hsolid
- Isludge
- Jfertiliser
- Kcrops
16What can be done with the biogas produced by digesters?
- ABurned to generate electricity
- BBurned to produce hot water and steam for central heating systems
- CUsed as a fuel for buses
- DUsed to build furniture
17Biogas digesters are very useful is remote parts of the world without access to mains [blank_start]electricity[blank_end]. They can produce [blank_start]biogas[blank_end] from human [blank_start]sewage[blank_end], which solves the problem of safe sewage [blank_start]disposal[blank_end].
- Aelectricity
- Bbiogas
- Csewage
- Ddisposal
18At [blank_start]low[blank_end] temperatures, the decomposer bacteria [blank_start]reproduce[blank_end] and res[blank_start]pire[blank_end] [blank_start]slowly[blank_end] so very [blank_start]little[blank_end] biogas is released.
Above [blank_start]45[blank_end] degrees the [blank_start]enzymes[blank_end] in the [blank_start]bacteria[blank_end] are [blank_start]denatured[blank_end] and the bacteria are [blank_start]killed[blank_end].- Alow
- Breproduce
- Cpire
- Dslowly
- Elittle

- Genzymes
- Hbacteria
- Idenatured
- Jkilled
19Other methods of transferring [blank_start]energy[blank_end] from biomass include the burning of fast-[blank_start]growing[blank_end] trees, and the use of bacteria and [blank_start]yeast[blank_end] in the [blank_start]fermentation[blank_end] process.

- Cyeast
- Dfermentation
20[blank_start]Alcohol[blank_end] made from [blank_start]yeast[blank_end] can be used as a [blank_start]clean[blank_end] [blank_start]biofuel[blank_end]. Ethanol produces [blank_start]less[blank_end] [blank_start]pollution[blank_end] than [blank_start]petrol[blank_end] or d[blank_start]iesel[blank_end] when it is burned but it doesn't produce as much [blank_start]energy[blank_end] as [blank_start]petrol[blank_end] or [blank_start]natural[blank_end] [blank_start]gas[blank_end]. Therefore is is mixed with [blank_start]petrol[blank_end] to make [blank_start]gasohol[blank_end]. [blank_start]Gasohol[blank_end] is used to run [blank_start]cars[blank_end] in countries that have [blank_start]large[blank_end] sugar can reserves but [blank_start]low[blank_end] [blank_start]crude[blank_end] [blank_start]oil[blank_end] reserves, like [blank_start]Brazil[blank_end].

21Advantages of Biofuels:
1.) The [blank_start]burning[blank_end] of [blank_start]biofuels[blank_end] does not cause a net increase in [blank_start]greenhouse[blank_end] [blank_start]gases[blank_end], provided that they are [blank_start]burned[blank_end] at the same [blank_start]rate[blank_end] as the [blank_start]biomass[blank_end] is being [blank_start]produced[blank_end].
2.) The land cleared for biofuel crops should not already be covered in vegetation.
3.) Biofuels are [blank_start]renewable[blank_end] - plants can be grown [blank_start]quickly[blank_end] and e[blank_start]asily[blank_end], unlike [blank_start]fossil[blank_end] [blank_start]fuels[blank_end]
4.) [blank_start]Biofuels[blank_end] are [blank_start]cleaner[blank_end] than [blank_start]fossil[blank_end] [blank_start]fuels[blank_end] - they produce much [blank_start]less[blank_end] [blank_start]air[blank_end] [blank_start]pollution[blank_end] when [blank_start]burned[blank_end]- Aburning

22What is soil a mixture of?
- AMineral particles
- BHumus (dead, decaying animal and plant material)

- ELiving organsisms
- FPlastics
- GFlowers
23A [blank_start]fertile[blank_end] soil contains a lot of [blank_start]air[blank_end] [blank_start]spaces[blank_end]. Living organisms in the [blank_start]soil[blank_end] need the [blank_start]oxygen[blank_end] so they can [blank_start]respire[blank_end]. The also need [blank_start]water[blank_end] for their [blank_start]life[blank_end] processes

24What are the three types of soil?
- ASandy - with large mineral particles
- BSandy - with small mineral particles
- CClay - with small mineral particles
- DClay - with large mineral particles
- ELoam - a mixture of clay and sand
25Plants need soil to grow and soil provides them with....
- AA source of minerals, e.g. nitrates. phosphates
- BWater for photosynthesis and transpiration
- CAnchorage for roots to hold the plant upright
- DLiving organisms
- EAir spaces
26Humus is important for [blank_start]fertile[blank_end] soil as the material it is made from releases [blank_start]minerals[blank_end] through the process of [blank_start]decomposition[blank_end]. It also increases the [blank_start]air[blank_end] [blank_start]content[blank_end] of the [blank_start]soil[blank_end].

27Air volume in soil experiment:
1.) Place [blank_start]soil[blank_end] sample in large [blank_start]measuring[blank_end] [blank_start]cylinder[blank_end]
2.) Add [blank_start]water[blank_end] to the [blank_start]100[blank_end] cm cubed mark
3.) Place [blank_start]lid[blank_end] on cylinder and [blank_start]shake[blank_end] up and down to release [blank_start]air[blank_end] [blank_start]bubbles[blank_end].
4.) Record [blank_start]new[blank_end] level of water. [blank_start]Initial[blank_end] reading minus [blank_start]new[blank_end] reading is the volume of [blank_start]air[blank_end] in the [blank_start]soil[blank_end]
This method is not entirely accurate as some of the water will have entered the [blank_start]air[blank_end] [blank_start]spaces[blank_end] in the [blank_start]soil[blank_end] before the first reading of the level of water is taken. This problem can be overcome by using [blank_start]known[blank_end] volumes of water and soil.- Ameasuring

28Water content of soil:
1.) [blank_start]Weigh[blank_end] and record [blank_start]soil[blank_end] sample
2.) Heat [blank_start]soil[blank_end] in oven for [blank_start]24[blank_end] hours to [blank_start]evaporate[blank_end] [blank_start]water[blank_end] then re-[blank_start]weigh[blank_end]
3.) Heat soil for further [blank_start]24[blank_end] hours and re[blank_start]-weigh[blank_end]
4.) [blank_start]Repeat[blank_end] this process until there is no further [blank_start]loss[blank_end] of [blank_start]mass[blank_end]
5.) [blank_start]Initial[blank_end] Mass - [blank_start]Final[blank_end] Mass = Mass of Water- AWeigh

2.) [blank_start]Weigh[blank_end] and record sample
3.) Continue steps 1 and 2 after [blank_start]stirring[blank_end] soil sample. [blank_start]repeat[blank_end] process until their is no further [blank_start]loss[blank_end] in [blank_start]mass[blank_end]
4.) [blank_start]1[blank_end]st mass - [blank_start]2[blank_end]nd mass (after [blank_start]burning[blank_end]) = mass of humus- Adry
