During the winter months, water on the surface of a pond will typically freeze and this ice acts as an insulator for the water beneath it. as a result, aquatic life is able to survive during the cold winter. the reason that this water expands upon freezing is due to

Which animal is a producer in this ecosystem

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.

The process of replication is the same for all living things because
