Heterogeneous mixture with larger particles that never settle

colloid

Explanation:

A colloid is a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
