Answer:
Option A and C and D
Explanation:
Gylcogen is synthesized through a series of reactions through the assistance of enzymes. When glucose enter into the cell, it is converted into glucose 6-phosphate and then into glucose 1-phosphate and finally into uridine 5ʹ-diphosphate-glucose. In glycogenesis, glycogen is broken down into glucose 1-phosphate with the help of two glycogen phosphorylase. In the next stage the glycogen debranching enzyme untangles the branch points.
Hence, option A and C and D are correct
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.
If the Earth were a disk with its surface perpendicular to the rays of sunlight, each point on it would receive the same amount of radiation. <span> However, the Earth is a sphere and aside from the part closest to the sun, where the rays of sunlight are perpendicular to the ground, its surface tilts with respect to the incoming rays of energy with the regions furthest away. Hope this answers the question.</span>
