Answer:
The correct answer will be-
Case I- option-B
Case-II-option-B
Explanation:
A scientific method is the best procedural approach to explain the natural phenomenon. The method includes various steps which begin with the making the observation. The observation leads to the asking the scientific questions which could be answered by proposing a hypothesis.
The hypothesis must be tested through experiments which could prove and disprove the hypothesis and can answer the natural phenomenon.
<u>Case-I</u>
In the given situation of the question in which a person notices or observes the fields of grass and grass and native flower. Since the researcher notices the fields, they are performing the first step of the method that is "making an observation" and thus Option-B is the correct answer.
<u>Case-II</u>
In the situation, which discusses the number of birds in the fields shows the "dependent variables". The dependent variable is the parameter which is studied in the experiments. Since in the given conditions the number of birds is being studied, therefore, Option-B is the correct answer.
Answer:
1. 2. chemicals in the injected fluids can get into groundwater that is used for drinking water;
B). Hydraulic fracturing allows geologists to capture natural gas stored in the pore spaces of shale.
Explanation:
- Fracking is a huge amount of the water that must be transported to sight at a significant environmental cost and occurrence of the minor tremors and is environmentally and potentially dangerous chemicals of they escape during the drilling and pollute the groundwater.
- And the hydraulic fracking is drilling methods used to extract the natural oil and gas from deep inside the earth and is used to study the geology of the earth.
