Three major groups of filament systems comprising the cytoskeleton are all composed of polymers of assembled subunits, which vary in thickness when assembled. Which is the CORRECT order, from smallest to largest, of the filament systems

A. microtubules, microfilaments, intermediate filaments
B. intermediate filaments, microtubules, microfilaments,
C. microfilaments, microtubules, intermediate filaments
D. none of the above

Option D

Explanation:

The three types of cytoskeleton vary in their size and their compositions. The smallest of the cytoskeleton is the microfilament made up of monomers actin filaments and measuring about 8nm external diameter.

The next is the intermediate filament measuring about 10nm external diameter. Microtubules are the thickest and are mostly made up of polymers of alpha and beta tubulin.

Option D.

Explanation:

Filament system refers to the structure or long chain of protein present in the cell. The cell shape is formed by three polymer system that make up the cytoskeleton. These three types are microfilament or actin filament, intermediate filaments and microtubules.

The microfilament is the thinnest of the cytoskeleton and it is found in the cytoplasm of eukaryotic cells. It provide support for the cell.

Intermediate filaments provide mechanical support for the cell plasma.

Microtubules are hollow that form the cytoskeleton, they give shape and support to the cell.

It should be microfilament ( thinnest), intermediate filaments ( thick) and microtubules ( thickest).

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
