Question
Though the plastic PET (“P-E-T”) generally lacks this property, Ideonella sakaiensis (“eye-dee-oh-NELL-uh sah-kai-EN-sis”) can digest it. For 10 points each:
[10e] Name this property possessed by compounds that can be decomposed by microorganisms.
ANSWER: biodegradable [or biodegradability or biodegradation; prompt on bioremediation; prompt on degradability or degradable or degradation]
[10m] This term denotes the process of biodegradation into simple inorganic compounds. This term also refers to the biological process by which inorganic compounds nucleate and grow in an organic matrix, such as hydroxyapatite (“hydroxy-apatite”) crystals forming on collagen.
ANSWER: mineralization [accept remineralization or mineralized tissues; accept bone mineralization or enamel mineralization; accept biomineralization or bioprecipitation; prompt on descriptions of forming minerals]
[10h] Post-mortem bone mineral uptake of rare-earth elements is increased if they have this property, which, for bone, means an element has an ionic radius similar to divalent calcium. More often, this geochemical property refers to elements that preferentially partition into the solid phase during partial melting.
ANSWER: compatibility [or compatible elements]
