Explanation:
Step-by-Step
Magma composition determines both eruption type and volcano type.
Composite cones are built of felsic to intermediate lava and shield volcanoes of mafic lava.
Cinder cones are made of small fragments of a variety of compositions usually from a single eruption.

Answer:
an amino acid with a C=O group is replaced by an amino acid with an O-H group
Explanation:
When an amino acid is substituted by another with opposite properties the replacement will modify the structure (and consequently also the function) of the resulting protein. For example, it is expected that the replacement of amino-acid residues with different solubility will alter the protein’s structure and this protein will establish different interactions with water, cell structures, or further segments of the protein. Therefore, in the cases above enumerated, only C-O and O-H groups have similar properties (i.e. they are hydrophilic and have polar bonds), and thereby it is expected that this replacement has no significant incidence on the protein’s structure and function.
