The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.
The statement "When levels of the amino acid are high, it binds to the repressor, allowing synthesis of this amino acid to proceed" (A).
E. coli needs amino acids to survive. It can ingest the amino acid, Tryptophan from the environment. When the levels of Tryptophan are low, it can synthesize Tryptophan by using enzymes that are encoded in five genes. These genes lie next to each other in the tryptophan operon. If tryptophan is available in the environment, E. coli will not synthesize it.
Recycling Causes Increased Environmental Problems
The process of recycling an old product into something reusable uses energy and creates pollution. Critics claim that recycling is simply a zero-sum game, where the pollutants and waste from making new goods shift into the recycling industry.
Behavioral isolation. This is when animals that can otherwise mate do not mate because of differences in courtship behavior. These animals choose to mate with animals of their own species.
