Mixtures are heterogeneous forms of matter. Mixtures are composed of variable proportions of molecules and atoms. Compounds are homogeneous forms of matter. Their constituent elements (atoms and/or ions) are always present in fixed proportions (1:1 depicted here).

Answer:

1}   voluntary muscles ; they are in direct control of our nervous system i.e we can control their contraction and relaxation  ( ex striated/ skeletal muscles )

  involuntary muscle : they can not be control by our nervous system (ex smooth and cardiac muscles)

2} a mixture is a material made up of two or more different substances which are not chemically combined . A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.
