Which of the following statements about minerals is false? a. minerals reflect light in different ways. b. the color of a mineral's powder doesn't change. c. the densities of many minerals are quite similar. d. a mineral can break in only one way.

B. The color of a mineral's powder doesn't change.

C. The densities of many minerals are quite similar.

D. A mineral can break in only one way.

A mineral is a naturally occurring inorganic compound. It is a chemical compound that usually found in crystalline form. The color of the mineral's powder can change because of the oxidation or reduction of particles present in it. The density of many minerals cannot be same because all mineral particles exhibit different composition of atoms or molecules which are responsible for physical and chemical structure of minerals. Hence, minerals vary in density. A mineral can be broken down into many ways like fracture, cleavage and other methods.  

answer; both surfaces of the membrane are nonpermeable

loss of sensation to pressure and touch

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
