It is called an amniotic egg.
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 After the growth of Penicillium it was withdrawn from the broth.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:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.
Answer:
Option). Increasing enzyme, increasing substrate, increasing co-factors
Explanation:
Enzymes are bio-catalysts that increase the rate of a chemical reaction by decreasing its activation energy. As enzymes are catalytic molecules, increasing enzyme concentration would increase rate of reaction.
Substrates are those substrates that react with other molecules to form products. Thus, increasing the concentration of substrates, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Co-factors are non-protein compounds or ions, which are required for proper functioning of many enzymes. Thus, increasing the concentration of co-factors, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Thus, the correct answer is option). 'increasing enzyme, increasing substrate, increasing co-factors.'
