Aquired traits arent passed onto offspring and natural selection takes place over a long period of time over many generations so only genetic traits can change over a period of time whereas aquired traits, eg a lost limb, are random and one off
The best answer would probably be observation because a hypothesis and theory is not always reliable. an observation describes what IS happening during the experiment.
Based on a ruler in centimeters, with ten divisions between each centimer mark, you will have marks at every 0.1 cm.

Thus, the hydrogen bonds between cytosine and guanine is the stronger.
