A scientist made a radioactively labeled probe using viral DNA. If the probe
hybridizes with a small piece of DNA isolated from human tissue, the
scientist could conclude any of the following except:
A. the virus contaminated the reaction that made the probe.
B. the Geiger counter that detected radiation was broken.
O C. the human genome might contain at least one viral gene.
D. the virus uses a different genetic code than humans.

Atree root breaking a rock into smaller fragments is an example of both and mechanical weathering. when rocks are exposed to heat, they which can contribute to thermal stress. when harmful gases, such as sulfur dioxide and nitrogen oxide, react with water in the atmosphere, they can produce the agent of erosion involved in stream erosion is when the ground is so saturated that it can't absorb rainfall or when rain falls so quickly that the ground can't absorb the water, forms. a/an is a huge, heavy, moving body of ice that picks up rocks and sand and erodes the ground beneath it as these materials scrape across it. hot arid climates are prone to erosion by rows of trees and shrubs planted to protect fields from wind erosion are known as
