Should fracking be used to release natural gas and oil ?
oksian1 [2.3K]

Explanation:

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.
  • Proppants in fluids channeled into formations can lead to ground water contamination.
  • In areas where fracking is done, there might be an exposure to harmful chemicals.
  • Destruction of the natural habitats of animals.

const2013 [10]

Answer:

The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.

Explanation:

Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.
