Alex listed the typical steps of fossil formation. 1) an organism dies. 2) the remains fall to the bottom of the ocean. 3) the soft portions decay, and the hard portions remain. 4) the sediment becomes rock. which statement describes the missing step?

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.

Explain why biological control methods are generally environmentally superior to chemical pest control methods.
