The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
Hope this was able to help you! I went through my answer and bolded the more important parts, and parts more useful for answering the question.

Answer:
The answer is c. net barriers.
Non-native species can do a great harm to native species or ecosystem and there are many ways to control them. Net barriers are mechanical control. Pesticides and herbicides are chemical control. There are also natural (biological control) control, such as diseases and pests, and environmental control, by altering the environment.
Answer:
Permeability
Explanation:
Permeability is usually defined as the property of rock in which the water (liquid or fluid) can easily percolate down into the deeper zone, through the interconnected pore spaces.
There are some factors that control the permeability, such as the shape and size of the voids, void ratio and the degree of saturation.
A highly permeable rock will allow more water to percolate through the voids in comparison to a low permeable rock. This percolated water eventually mixes with the groundwater.
For example, Gravels have high permeability, and Granite has low permeability.
