Q: A madrigal is a secular vocal music composition of the Renaissance and early Baroque eras. Traditionally, polyphonic madrigals are unaccompanied; the number of voices varies from two to eight, and most frequently from three to six.

Can we conclude that a madrigal is a renaissance secular composition for four or five voices?

The act of performing surgery may be called a ''surgical procedure'', ''operation'', or simply ''surgery''. In this context, the verb ''operate'' means to perform surgery. The adjective ''surgical'' means pertaining to surgery; e.g. surgical instruments or surgical nurse. The patient or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of surgeon, surgeon's assistant, anesthesia provider, circulating nurse and surgical technologist. Surgery usually spans minutes to hours, but it is typically not an ongoing or periodic type of treatment. The term ''surgery'' can also refer to the place where surgery is performed, or, in British English, simply the office of a physician, dentist, or veterinarian.

IN: Is it true that could two molecules contain the same sets of atoms but have different properties?

An isomer (/asmr/; from Greek , isomeres; isos = ''equal'', meros = ''part'') of a molecule has the same number of atoms of each element, but has a different arrangement of the atoms. It has the same molecular formula as the other molecule, but with a different chemical structure. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are two main forms of isomerism (/asmrzm, as-/): structural isomerism (or constitutional isomerism) and stereoisomerism (or spatial isomerism).
