How might the collapse of the carboniferous rainforests have affected earths carbon cycle? a. the loss of vegetation would have decreased the total amount of carbon in earths carbon cycle. b. over time, the decaying vegetation would have absorbed a large amount of carbon dioxide from the atmosphere. c. over millions of years, decaying vegetation would have been buried and its carbon turned into fossil fuels. d. the total amount of carbon in the carbon cycle would have increased as the vegetation decayed.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
