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.

Nonspecific permeases a. allow a variety of molecules to cross the cytoplasmic membrane. b. allow only water to cross the cytopl
andriy [413]

Answer:

a. allow a variety of molecules to cross the cytoplasmic membrane

Explanation:

The cells have different molecules in its membrane. As a membrane the main function of it is to regulate the income and outcome of substances that the cell needs or the cell has like some wastes.

Some of these molecules can be some proteins like the permeases, that is going to  regulate the solutes that can enter the cell, but since they are non specific, that means that can not make the difference among one carbohydrate and another (as an example).

Water's ability to dissolve a wide variety of molecules is important, but more important is the hydrophobic effect, which drives
NeX [460]

Answer and explanation;

The hydrophobic effect is the observed tendency of non-polar substances to aggregate in an aqueous solution and exclude water molecules. Hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the non-polar solute.

Introduction of such a non-hydrogen bonding surface into water causes disruption of the hydrogen bonding network between water molecules.

Water dissolves molecules (proteins and nucleic acids) that display on their solvent-accessible surfaces groups that can h-bond [hydroxyl, carbonyl, ester groups; they're polar uncharged...also charged groups; protonated amines, carboxylates and phosphate ethers.

Molecules with internal h-bonds dissolve in water, some/all internal h-bonds may be in dynamic exchange with h-bonds in water .

Polar nature of water contributes to ability to dissolve non-ionic polar organic molecules, such as phenols, esters, amides; have large dipole moments and interaction with water dipole promotes solubility in water.
