What role do hypotheses play in scientific inquiry?

Hypotheses play a critical role in scientific inquiry by providing testable explanations for observed phenomena. They help guide the research process by establishing a framework for investigating a specific question or problem. Through testing and analysis, hypotheses can either be supported or refuted, ultimately contributing to the advancement of scientific knowledge.


Which observation would provide indirect evidence that the bubbles are O2?

If the bubbles produced can relight a glowing splint or support combustion, it would provide indirect evidence that the bubbles are oxygen (O2). This is because oxygen is required to support combustion.


What is one characteristic of a scientific theory?

There are many criteria for a scientific theory, it would kill me to list just one, so I'm goint to let you pick from the list. It should be testable. It should be able to be falsified. It's predictions must conform to the observations It should have been repeatedly tested


Which observation would provide indirect evidence that the bubbles are not oxygen?

If the bubbles do not relight a glowing splint, it would suggest they are not oxygen. Oxygen is a gas that supports combustion, so if the bubbles do not allow the splint to reignite, it indicates they are not oxygen.


What evidence is there to indicate that the Epsom salts and ammonia reacted?

Evidence of the reaction between Epsom salts (magnesium sulfate) and ammonia would include observing the formation of a white precipitate (magnesium hydroxide) and the release of ammonia gas, which has a distinct pungent smell. Additionally, one could measure the change in pH, which would increase as the ammonia reacts with the magnesium sulfate to form magnesium hydroxide.

Who do you think will win Romney or Obama?

We at Answers.com were hesitant to make predictions, but most of the reliable pundits, pollsters, and political scientists did make predictions: based on the available evidence, the majority said that President Obama would win. And that is exactly what happened.

What is the similarity between conclusion and prediction?

A conclusion can only be made with solid evidence. A prediction is a foretelling of the future, a guess of what could happen soon. Predictions are not always the truth, but if there was evidence to back up the prediction, then a conclusion would be made to make it true.


What would you predict might happen to the water table if a large industry using a well were built in an area?

It would be unwise to make predictions in the absence of evidence. On the other hand, it would be prudent to test for the possibility that the water table might fall.


How does back ground radiation provide evidence for the big bang theory?

If an isotropic microwave radiation, with a spectrum identical to that of a 2.7 K blackbody, did not exist, then Big Bang Cosmology would be pretty much refuted. But it DOES exist, and it's nature is pretty much exactly as predicted by BBC. It, like all other observational evidence, supports BBC and refutes its alternatives.


When would you use a graph?

How would you respond to someone who tells you that he or she does not believe in bilogical evolution because it is just a theory?

Calmly explain the definition of a theory i.e. a hypothesis which has been supported by much and varied evidence and has made tested and confirmed predictions. However, those who make this claim often use it to justify personal opinion, so a logical explanation won't do much to change their mind (if they even listen to it at all).


How do you defend against false allegations of terrorist threat?

Defending against false allegations of terrorism is much like defending against any other false allegations. The general idea is, lies are refuted by telling the truth. You would have to examine the basis for the allegations, whatever evidence or reports have been collected, and explain what really happened, and produce whatever confirming evidence you can, to prove your case.

What evidence might change scientist's minds about astrology?

Some information that would help: unambiguous evidence that there are systematic, independently verifiable differences in personality based on date and time of birth, and systematic, independently verifiable evidence that unambiguous and non-frivolous predictions made from astrological readings have later come true.


Can theories be disproven?

Yes, theories can be disproven if evidence is found that directly contradicts their predictions or explanations. This is a fundamental part of the scientific method, where theories are continuously tested and revised based on new evidence.
