What is the primary purpose of applying environmental adaptation engineering in agriculture?
|
2. To recycle and reuse agricultural waste sustainably |
|
1 - We don't want to focus on fertilizers too much as a way for better crop yield as it can get expensive
3 - Ecosystem play a big part in agriculture but its' effect can be substituted by other methods
4 - we do not want to use chemicals as pest control as it can act as poison to unsuspecting consumers
5 - There are other factors other than soil nutrient that can affect agricultural crops

Which method best exemplifies waste-to-resource conversion in sustainable farming?
|
5. Plastic mulching |
|
Open air burning releases CO2 into the air which can cause global warming
Anaerobic produces less energy than aerobic so it might not be an effective way to produce energy
Excessive Irrigation can waste a lot of water

Which property is most critical for biocompatibility of SMHs?
|
1. Chemical inertness and non-toxicity |
|
It's important for SMHs to be unreactive to chemicals as inside the human body, there are tons of chemical processes going on. Without the inertness, SMHs can interrupt reactions and produce unwanted products that can cause harm to the human body.
