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.
I think the correct answer among the choices listed above is option B. The process that creates specialized cells like blood cells, nerve cells, or bone cells, is called differentiation. It is a process where generic embryonic cells become specialized cells.
Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

If two heterozygous individuals are crossed, the results of the cross are as follows:
- SS - spotted condition
- 2 Ss - Spotted condition
- ss - non-spotted condition
<h3>What is an Heterozygous Cross:</h3>
According to this question, the gene coding for spotted condition. The allele for spotted condition (S) is dominant over the non-spotted condition (s).
If two heterozygous Dalmatian dogs are crossed i.e. Ss × Ss, the allele combination for each gamete is as follows:
The following offsprings will be produced:
- SS - spotted condition
- 2 Ss - Spotted condition
- ss - non-spotted condition

This is baby stuff tbh. But it is A. You need water to live. Food to live. Air obviously and a shelter
