Two 7th grade students made models of a population of bacteria before and after they were treated with an antibiotic for several generations. Use the models to answer the question. Which statement below is the best explanation regarding the accuracy of the student’s models?

Asimply means that over time there was some sort of change.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
