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.
D. Ice is less 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.

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
