Answer 1

nothing because everything has some components in it

Explanation:

blood- RBC,WBC

milk-protiens,fats

etc..

Answer 2

Answer:

starch sollution

Explanation:

which substance dissolved (solute) in solvent has the particle size of less than 10-9 m or 1 nm. Simple solution of sugar in water is an example of true solution. Particles of true solution cannot be filtered through filter paper and are not visible to naked eye.

Colloidal Solution is a heterogeneous mixture in which particle size of substance is intermediate of true solution and suspension i.e. between 1-1000 nm. Smoke from a fire is example of colloidal system in which tiny particles of solid float in air. Just like true solutions, Colloidal particles are small enough and cannot be seen through naked eye.They easily pass through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane.

blood, starch, ink : Colloidal Soln.

sugar sol., salt sol : true soln.
