What property of water allows fish to survive in a lake that is frozen over? A. Ice is more dense than water which means water condenses when it freezes allowing the ice in a lake to float on top of the water preventing the water below from freezing.

B. Ice is more dense than water which means water expands when it freezes allowing the ice in a lake to float on top of the water preventing the water below from freezing.

C. Ice is less dense than water which means water condenses when it freezes allowing the ice in a lake to float on top of the water preventing the water below from freezing.

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.
