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.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.

i think the answer would be a. after sentence 14! i hope i at least a little
