Review evidence
Scientists observe and experiment the natural phenomenon. series of tests and observations allow them to come to solutions on whatever it is they are studying or trying hypothesize on. Carlo
When scientists share the results of their work with other scientists, this contributes to the development of science, and everybody benefits. Science is about increasing the knowlege that the human race has about the universe in which we live, and that can only happen when scientific findings are publsihed. In addition, scientists benefit by having the accuracy of their work checked by other interested scientists, and by having the further implications and possibilities of their work explored by other scientists. No one scientist can do everything by him or herself. Even Isaac newton, who was probably the greatest scientist of all time, made a point of thanking other people whose earlier work made it possible for him to make that advances that he made (or as he poetically put it, if I have seen farther than others, it is because I am standing on the shoulders of giants).
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
Microscopes allow scientists to confirm what is happening on a small scale. For example, we can observe the effects of a new drug on liver cells. It merely makes it easier to empirically check theories.
for a-plus biology answer to that question is: methods
A reliable investigation will allow you to make conclusions that are supported by the data you have collected,and that reflect the findings of other scientists.
Scientists design experiments to test hypotheses and gather data to support or refute their theories. By designing experiments, scientists can control variables, ensure accuracy and reliability of results, and draw meaningful conclusions based on empirical evidence. Experiments allow scientists to investigate relationships between different factors and understand the natural world better.
With a micro array , scientists can examine how active thousands of genes are.
Universities would allow scientists to investigate their theories even if they contradicted Catholic teachings.

Scientists ensure the accuracy of others' work by peer reviewing publications, replicating experiments, and sharing data for verification. They also attend conferences and collaborate with others in the field to discuss and validate findings. Additionally, scientists maintain transparency in their methodologies and results to allow for scrutiny and validation by others.
