IN: Is it true that is a denatured protein still able to function?

Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure and secondary structure which is present in their native state, by application of some external stress or compound such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), radiation or heat. If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Protein denaturation is also a consequence of cell death. Denatured proteins can exhibit a wide range of characteristics, from conformational change and loss of solubility to aggregation due to the exposure of hydrophobic groups. Denatured proteins lose their 3D structure and therefore cannot function.

OUT: no

IN: Is it true that is it possible to have a wolf as a pet?

Wild wolves are sometimes kept as exotic pets, and in some rarer occasions, as working animals. Although closely related to domesticated dogs, wolves do not show the same tractability as dogs in living alongside humans, and generally, much more work is required in order to obtain the same amount of reliability. Wolves also need much more space than dogs, about 25 to 40 square kilometres (10 to 15 sq mi) so they can exercise.

OUT: yes

IN: Is it true that a cappella indicates a choral work performed with accompaniment?

A cappella (a kkapplla) (Italian for ''in the manner of the chapel'') music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is usually accompanied singing. The term ''a cappella'' was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.
