A mold was developing in some of the culture dishes used by Sir Alexander Fleming and was eliminating some of the bacterial population. The hypothesis is that the mold was generating a chemical, which was toxic to the bacteria in the dishes and killed them.
The hypothesis was examined by separating the Penicillium and administering it into the solution of nutrient broth. After the growth of Penicillium it was withdrawn from the broth. The broth was then eventually supplemented to the bacteria and the bacteria died. Thus, it can be concluded that the hypothesis is supported.
Bleaching I believe is the correct answer.
Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
People have manipulated the genome of horses and ponies in the lab to produce the breeds we know today
Chargaff found out that t<span>he ratios of thymine and adenine were equal and the ratios of guanine and cytosine were equal. He then created the Chargaff's rule states that double stranded DNA has a 1:1 ratio between pyrimidine and purine bases. With this, </span><span>amount of guanine bases is equal to cytosine bases while the amount of adenine bases is equal to thymine bases.</span>
