That is a philospher. Someone who thinks they can be God. Gosh.
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: They are not.
Explanation:
When it comes to molecular bonding, a single additional atom can change the characteristics of the compound. This is why Carbon Dioxide is different from Carbon Monoxide even though they both contain only Carbon and Oxygen atoms albeit in different quantities.
In this scenario the compounds described are Hematite which has two iron atoms to three oxygen atoms and Magnetite which has three iron atoms to four oxygen atoms. The presence of the different number of the same atoms made these compounds different.
The Earth's mantle is very important. It is important for the Earth's crust evolution, as well as being the provider of thermal and mechanical forces for plate tectonics. The mantle is what covers the most part of Earth inside if it is not there, then the heat of the core will burn the Earth's crust. And the mantle does make up 84% of Earth's volume, so that wouldn't be good!
