i had this question and it was price
hope this helps
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 After the growth of Penicillium it was withdrawn from the broth.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.
Ok so let me help you with this: Desertification is the process in which an environment becomes drier in climate, typically causing plant and animal life to decrease significantly. Researchers have found that areas around current deserts are becoming desertified, therefore expanding the desert.<span> Areas that may have once had adequate rain may now not receive much rain at all, causing desertification. I know this is going to be useful</span>
