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 After the growth of Penicillium it was withdrawn from the broth.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.
Answer:
<h2>Coevolution</h2>
Explanation:
Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.
In coevolution , two or more species reciprocally affect evolution of each other by natural selection.
Coevolution Examples:
There are lots of examples of coevolution, some are here
i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.
ii) coevolution of Herbivores and plants,
iii) coevolution of Acacia ants and Acacias and
iii) coevolution of Flowering Plants and Pollinators and many others.
Answer:
