The two main categories of bacterial food poisoning
What are infective, and toxin-type?
100
Being without reliable access to sufficient, affordable, quantities of food.
What is Food Insecurity?
100
All aspects of the processing, preparation, storage, cooking and serving of food to make sure that it is safe to eat/does not make people ill.
What is food hygine
100
chronic food insecurity; food insufficient to meet basic energy requirements/provision of essential nutrients on continuing basis.
What is undernourishment
200
Sufficient food is available, supplies are relatively stable, those in need of food can obtain it
What is Food Security?
200
A substance in which there are double bonds present between the carbons of the fatty acid chains.
What are Roundup Ready Crops?
200
List two waysin which manufacturers can minimize the damage caused to the environment during the life of an electronic product
What is minimize use of toxic materials;
design products which last longer;
design for disassembly;
design so product can be upgraded;
design using recycled material;
design using reuseable parts;
design for recycling;
design for minimal energy usage;
200
Why should a balance diet contain some fat?
What is Fact acts as vehicle to help the absorption of fat soluble vitamins; these prevent fat soluble vitamin deficiencies.
Fat provides energy; low fat diets may not provide enough energy.
Some fatty acids are essential; they cannot be produced y the body and must be provided by the diet for health.
200
List two implications of climate change that may lead to increased undernourishment in the developing world.
What is floods, drought, temperature change, erratic weather patterns, gales/high winds.
300
Increase in microwave cooking, bulk buy food offers, more people eating away from home.
What are lifestyle factors that lead to increased chances of food poisoning?
300
A substance in which there are double bonds present between the carbons of the fatty acid chains
What is a Saturated Fatty Acid?
300
to show information about contents, keeping contents fresh clean and safe, promotion of other products.
What are functions of packaging?
300
Implication of excess fat intake for health
High dietary fat intakes, especially of saturated fat, can lead to increased level of cholesterol; this can lead to coronary heart disease/obesity; resulting in poor health.
300
Outline one strategy to deal with the implications of climate change to increased undernourishment.
What is irrigation/flood prevention schemes; ensure optimum water reaches food crops; desalination schemes;
remove salt from sea water and make it fit for agricultural use; develop different cultivars that are able to cope with the different conditions;
e.g. drought resistant/salt resistant;
400
Increased demand for lower cost food, ready-made meals increase in prevalence.
What are market pull’s effects on food development?
400
Freezers/blast chillers, microwaves, different packaging materials, enhanced food properties.
What are the effects of technology pushes?
400
Pertains to Coca- Cola: the design is easily recognized, color/ lettering is consistent, has become trusted brand.
How has the packaging helped the development of the Coca-Cola brand?
400
one consideration relating to the control of food hygiene for food which is available for purchase in the street
What is dust and other debris/people accidentally or deliberately coughing/spitting into the food/bird defecating; contamination of the food which is not properly heated would cause food poisoning; weather; hot temperature/climates will impact on food storage time; pollutin; from car exhaust/factories; use of utensils/tongs; to pick up food rather than use hands; keeping the food covered to prevent contamination.
400
Discuss one ethical issue underpinning public concerns about the safety of genetically modified foods
What is perceived safety issues,
ecological concerns,
economic concerns.
500
Outline one way in which converging technologies could be applied to national defence
What is technologies designed to keep humans remote from the combat zone;
secure communication of real-time information to front line combatants;
information gathering and processing technologies;
interfacing combatants with weapon systems;
500
Outline one way in which convergent technologies could enhance human communication.
What is removal of barriers to communication;
e.g. physical disabilities, language differences, geographic distance;
500
Outline one difference between a digital and an analogue signal
What is an analogue signal is continuously varying and can take any value;a digital signal takes discrete steps/can be represented as binary number/is on or off/0 or 1;
500
How sun drying of tomatoes preserves them
Lowers water activity/reduces water content; this prevents bacterial growth.
