Let me try: an example of a scientific question that can be investigated with an experiments is "at what temperature does iron melt"?Questions in physics ans chemistry are easily tested with experiments. an example of a scientific question that cannot be (I think) investigated with an experiments is "how does neuron activaton lead to us having the perception of free will"?Questions connected to human mind on a more general lever are not as easily tested with experiments: they need models rather than this.
<span>On a modern firearm, the feature that functions like the lock on a muzzleloader is the safety. The safety was added to modern guns to prevent them from accidentally firing, although it should be noted that a safety is a man-made mechanical device which makes it subject to failure at times.</span>
<span>The polymer that provides plants with their genetic traits is nucleic
acid. The answer is C. Nucleic acids are what made the DNA (deoxyribonucleic
acid). The DNA are composed of a nitrogenous base, phosphate and a sugar
(deoxyribose). The bases are adenosine, tyrosine, uracil and guanine. And they
are needed to be matched to carry the trait. The nitrogenous base is the traits that
contains the genetic material and are mostly composed of nucleic acids. </span>
