- Question
Select the correct statement about the process of scientific inquiry.
Options- A. The goal of scientific research is to prove the stated hypothesis.
- B. It is possible to test hypotheses, such as those involving historical events, without conducting experiments.
- C. If the results of an experiment do not support the hypothesis that is tested, the experiment is badly designed.
- D. All of the above
- Correct Answer
- It is possible to test hypotheses, such as those involving historical events, without conducting experiments.
ExplanationThe correct statement among the given options about the process of scientific inquiry is "It is possible to test hypotheses, such as those involving historical events, without conducting experiments."
Although it is not possible to carry out experiments to test hypotheses about evolutionary relationships between living groups or about the timing of the origin of major evolutionary innovations, such hypotheses can be evaluated by making predictions about the expected findings that would result from these hypotheses. Data can then be collected to test whether these predictions are correct.

Correct Answer: To decrease heat flow
Correct Answer: osmosis
Explanation:
Water reabsorption by the renal tubules is harmonally controlled and it is a osmosis mechanism.
Correct Answer: Aeolus
Correct Answer: unrelated to any realistic, known source
Explanation:
Free floating anxiety is also known as Generalised Anxiety Disorder in which the individual may be unable to identify specific triggers for the anxiety.
Correct Answer: Hypoxemia
Explanation:
Oxygen deficiency or decreased oxygen levels in the blood is a condition known as Hypoxemia.
Hypercapnia means High carbon dioxide levels in the blood.
Correct Answer: Glucose
Explanation:
Here cellulose, sucrose and glycogen are all the forms of glucose. Hence, glucose includes all the other three given options.
Correct Answer: Iron
Explanation:
Iron reacts with oxygen in the presence of moisture or water to form a red oxide called rust and the reaction involved is called as Redox reaction.
Correct Answer: Stimulus diffusion is a type of expansion diffusion in which the idea is acceptable or adopted but not in its original form and expanded to culturally acceptable For example : 1 Mc Donalds is also in India but not in beef Indians culture will not accept beef and so it is with different forms like veg, non veg but the idea is same 2 Yoga is an idea where in different regions use yoga for different reasons but the idea is same

Correct Answer: reforestation of the cedar forests of the northwest
Explanation:

After a forest fire, the whole forest had destroyed but after that again renewal of that forest is also an example of secondary succession.
