Scientific Laws and Theories Quiz The theory of evolution describes how organisms change over time. Scientists now use information in the DNA of living organisms to understand how they are related. The theory of evolution was developed before scientists discovered DNA; however, these new data still fit with and support the theory. What does this sequence of events tell us about the theory of evolution? It is a bad theory because it makes scientists biased. It is a good theory because it is able to explain new evidence. It is a good theory because it has changed greatly over time. It is a bad theory because it was formed before the discovery of DNA.

It is a good theory because it is able to explain new evidence.

Explanation:

The theory of evolution is a good theory because it has the ability to explain new evidence that occurs before and after this theory. This theory enable us to understand the changes that occurs in the form and structure of an organisms with the passage of time so we can conclude from this discussion that this theory of evolution is a good theory.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

because of
