It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.
eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.

The perirhinal cortex is particularly important in visual recognition and receives more input from the occipital lobe than from other cortical areas. In addition, the perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36. It obtains highly administered sensory information from all sensory regions and is usually accepted to be a significant region for memory.

I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.
Answer and Explanation:
Protein folding : It is the physical procedure by which a protein chain gains its local 3-dimensional structure, an adaptation that is normally naturally useful, in a quick and reproducible way. It is the physical procedure by which a polypeptide folds into its trademark and useful three-dimensional structure from curl. Every protein exists as an unfurled polypeptide or arbitrary curl when interpreted from a grouping of mRNA to a direct chain of amino acids. This polypeptide does not have any steady (dependable) three-dimensional structure (the left hand side of the primary figure). Amino acids cooperate with one another to create a well-characterized three-dimensional structure, the collapsed protein (the correct hand side of the figure), known as the local state. The subsequent three-dimensional structure is dictated by the amino corrosive grouping.
\The right three-dimensional structure is fundamental to work, albeit a few pieces of practical proteins may remain unfurled, so protein elements is significant. Inability to crease into local structure commonly creates inert proteins, however in certain occurrences misfolded proteins have changed or lethal usefulness. A few neuro degenerative and different ailments are accepted to result from the collection of amyloid fibrils shaped by misfolded proteins. Numerous sensitivities are brought about by off base collapsing of certain proteins, on the grounds that the invulnerable framework doesn't deliver antibodies for certain protein structures.
