Answer:

Frederick Griffith was the first scientist who discovered that cell contains some components that can be transferred to another cell and cause a permanent change(transformation) in the new cell.

To prove this he performed an experiment in which he took two strains of <em>Streptococcus pneumoniae</em> which contain one rough strain and one smooth strain. Rough strain was non-virulent strain and smooth strain was virulent strain.

So he injected smooth and rough strain in mice and saw that mice die when virulent strain is injected and survive when non-virulent strain is injected. Then he injected heat killed virulent strain in which mice survived.

Then he added remain of heat killed bacteria with live smooth strain of bacteria and infected the mice and saw that the mice was killed by non-virulent smooth strain of streptococcus.

After this experiment he concluded that cells contain some component later identified as DNA which can be transferred to new population of cells and transform these new cells.

How did the Mafia gain the interest and scrutiny of the public?
mihalych1998 [28]

Mafia gain the interest and scrutiny of the public through their unique and fearful actions.

Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.

The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.

How did the light and dark variations of the moth changer during the Industrial Revolution?
umka2103 [35]
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
