Answer:

Fracturing fluids such as return fluids represent a potential risk to groundwater and surface water, due to the existing connection with

aquifera recharge zones.

During drilling in the fracking it is possible that there is water contamination due to accidental spillages of contaminants, for example in the process of cementing the casing or integrity problems of the casing may result

in the migration of thermogenic methane gas into the water.

Another source of contamination arises from the possibility that a hydraulic fracture is connected to the surface, since a fracture hydraulic can intercept a natural fracture for example a geological fault

When fracturing substance migration can be promoted toxic substances present in the subsoil, such as mercury, radio, lead and arsenic, which may increase the occurrence of chemical reactions and the creation of new polluting substances.

Answer:

from what i read!! use own words

Explanation:

Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. ... The other possibility of pollution is when the water, which is mixed with chemicals and sand for the fracking process, comes back to the surface

Does fracking contaminate water?

No. They gave examples where fracking could contaminate water. For instance they state that "Injection of hydraulic fracturing fluids directly into groundwater resources" can cause contamination. ... The EPA also notes that disposing of fracking wastewater directly into surface water could contaminate drinking water.

<h2>The correct answer is: Mutualism.</h2>

Explanation:

Mutualism can be defined as a type of symbiotic relationship.
Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
In the given question, some micro-organisms survive in the digestive tract of the cattle.
These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
