Renald completed only one trial of his experiment. what effect will this most likely have?

the results are more likely to have errors.
the results are more likely to be precise.
the experiment will be harder to replicate.
the experiment will be easier to replicate.

The results are more likely to have errors.

Explanation:

An experimental process requires the repetition of a particular step during recording the observations. This process of repetition will allow the development of concordant readings. The similarities in the values of atleast three readings will suggest that the methodology applied is correct and results are accurate and precise. Accepting only one observation to include in the result will lead to inclusion of errors.

Renald completed only one trial of his experiment this will lead to the inclusion of the incorrect observation will likely to include errors in the results.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

i believe the correct answer is d
