Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them
defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.
Which individual's reasoning do you agree with more and why?

the backbone of the dna and rna compound is sugar phosphate.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
