Question

biotechnology
food production:
bread, yogurt, cheese,
wine, beer, pickled
products are examples

1. which of the following is a household example of biotechnology?

flowering of household plants
safe defrosting methods
shower scrubbing
bread making

1. part of the cleanup efforts for the deepwater horizon oil spill in 2010 involved

recombinant dna technology
bioremediation
polymerase chain reaction
biofuel production

Explanation:

1. Biotechnology in household context often involves using living organisms (like yeast in bread - making). Bread making uses yeast (a living organism) to ferment and rise the dough. Flowering of plants is a natural biological process not typically considered household biotechnology. Safe defrosting and shower scrubbing are physical or cleaning processes without using biological agents in a biotechnological sense.
2. Bioremediation is the use of living organisms (usually microbes) to clean up pollutants. In the case of the Deepwater Horizon oil spill, microbes were used to break down the oil. Recombinant DNA technology is about manipulating DNA (not directly related to oil - spill cleanup here). Polymerase chain reaction is a technique to amplify DNA. Biofuel production is about creating fuels from biological sources, not spill cleanup.

Answer:

1. Bread making
2. bioremediation
