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:
It would<u> reduce the dependence on traditional ways of living.</u>
Explanation:
- Living in a place were water and space are heated directly by sunlight or sun influence would be quiet interesting and challenging as the sun is the nearest star to planet earth and this star will continue to grow in size, and also the resources on surface of earth are finite and thus any overuse of these resources can lead to their depletion.
- Use of this solar light or heat is essential as its an inexhaustible resource that can be stored at specific temperatures and used in terms of lightning, billing waters from heat generated by sun photovoltaic cells.
- The same energy that is needed r warm the surface of the earth falling on rooftops of the house can recharge the energy bill of the entire country for which sun harvesting has to be implemented.
- Like solar terracing and many farmers and people have done gardening on their roofs and many innovative techniques are being developed for a sustainable future.
