“Silty loam” contains a higher proportion of silt than the common 40% sand, 40% silt, and 20% clay. Is this imbalance always a bad thing? Always; high silt soils drain poorly.
No; higher silt levels are usually preferred to the common balance.
Sometimes; however, some crops thrive in soils with high silt levels.
Yes; high silt levels make the soil infertile.

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.
