Quality control and proof of accuracy, to weed out contaminants or bias.

To make sure that the test results are the same and can conclude the result of the experiment will come up 100% of the time.
Scientists do their test more than once, or get their colleagues and peers to do the same experiment in order to verify the results of their experiment. This is called reproducing an experiment and its results.
Galileo was the scientist that had ideas about falling objects tested on the moon by astronauts more than 400 years after his death.
Describing a scientist as skeptical means they approach claims and hypotheses with questioning and critical evaluation rather than accepting them at face value. This quality is essential because skepticism drives scientists to rigorously test ideas, seek evidence, and avoid confirmation bias, ensuring that conclusions are based on reliable data rather than assumptions. Ultimately, skepticism fosters a more robust scientific method, leading to more accurate and trustworthy results.
Yes
Most of the time.

Repeating or replicating a test or experiment can reduce the chance for errors. For example, if you flip a coin once and get heads, you could conclude that you will always get heads when you flip the coin. If you flip the coin many times, you should realize the outcome is much closer to 50% of the time heads and 50% of the time tails. After one scientist does an experiment, a second scientist may want to run a similar test to determine whether the conclusions made by the first scientist were in fact accurate. Using the same or a similar method, anybody should be able to replicate the results.
yes because if you use the vertical line test it will not cross it more than once.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
Once a hypothesis have been confirmed through numerous experimental tests, it can then become a theory. Theories are much more powerful and expansive in scope than hypotheses. Once a theory has been established, it is the role of scientist to try and disprove a theory rather than to try to reinforce its proof.
To make sure that the test results are the same and can conclude the result of the experiment will come up 100% of the time.
No. Use the vertical line test along the Y axis and if the line is crossed more than once, you know that it isn't a function.
Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
It can occur more than once.
Yes. Unless you smoked more than once a day every day for more than a month. Then it could take up to 90 days.
