Oswald, McLeod, and McCarty determined the nature of the genetic material by using a similar experimental setup to Griffith's and systematically
destroying DNA, RNA, and protein of the virulent cells. Which finding
describes the results of their experiments?
A. When DNA was destroyed, virulent cells did not transform
nonvirulent cells.
B. When protein was destroyed, virulent cells did not transform
nonvirulent cells.
C. When RNA was destroyed, virulent cells did not transform
nonvirulent cells.
D. Virulent cells always transformed nonvirulent cells.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
