Answer:

<u><em>C. DNA from the S bacteria is necessary for bacterial transformation to occur.</em></u>

Explanation:

These series of experiments determined that DNA is the genetic material which gives rise to a particular type of cell. As we can see, the S bacteria with degraded proteins were able to grow when the proteins and RNA were degraded. But they were not able to grow when their DNA was degraded. This experiment proved that proteins or RNA are not the genetic material, rather DNA is the material related to inheritance.

Space can help us prepare the feutre Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.
