Fracking is the introduction of substances into a formation in order to increase they pore pressure and to increase natural drive of hydrocarbons.
Fracking has several environmental issues associated with it;
- Fracking leads to air pollution in case of blowout of gas pressure in formations, particles and dusts can become blasted into the environment.

Answer:
Fungi is a unique living organism and it is not considered plant or animal and forms its own kingdom Fungus. On of the most unique features of a Fungi is that its body is composed of thread like structure called Hyphae and produce fruiting bodies, in which spores are formed are help the fungus in reproduction.
Coming towards the question that what is the unique feature of the structure of Hyphae and fruiting body that helps them in their function.
1: Hyphae:
Hyphae are composed of thread like structures called Hypha that are filamentous in nature. Due to its filamentous nature, it helps the fungi to better absorb nutrients from soil and anchor the fungus well in soil.
2: Fruiting body:
The fruiting body is main organ of fungi concerned with reproduction. It has rounded cap like structure in which spores are formed and are disseminated from one place to another and help fungi in reproduction.
Hope it helps!
