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
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
Scientists can tell whether organisms are closely related by comparing their DNA. This will allow then to look at various traits and features so as to compare the relationship between organisms.
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.
With a micro array , scientists can examine how active thousands of genes are.
It allows scientists to see patterns in matter.
Universities would allow scientists to investigate their theories even if they contradicted Catholic teachings.
