A community should use sustainable practices to produce food because "it protects the environment, farming communities and farmed species".
<u>Answer:</u> Option B
<u>Explanation:</u>
The practice of sustainable food production is a united network that integrates several components with the development of each and every individual covered in the food chain in order to protect the environmental, economic and social well-being of a community.
The advantages of such practice are production of less greenhouse gases, fossil fuel utilization is minimized and more dependent on human labor inspite of chemicals and energy-intensive technology. Sustainable farms conserve scarce water resources, encourage biodiversity and build healthy soil through composting and planting techniques that cover crops.
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.
Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.
This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.
Redi was trying to prove spontaneous generation with his experiment. Although, it failed.
Spontaneous generation: When life forms from non-livings.
Redi disproved spontaneous generation, but proved biogenesis.
Biogenesis: When life comes from other living beings.
He proved biogenesis because the flies had reproduced when the jar was opened.
Answer:
Whether it's practical (like washing machines, tumble dryers, refrigerators, cars, flooring materials, windows, or door handles) or for leisure (like televisions, Blu-ray players, games consoles, reclining chairs, or toys), all these things are examples of technology.
