Answer: Option A. "Cytoskeleton"
Explanation:
Cytoskeleton can be defined as the network of protein filaments in the cytoplasm eukaryotic cells interlinking from cell nucleus to cell membrane.
There are three basic types of protein fibers present in cytoskeleton that includes micro filaments (Actin filaments ), microtubules and intermediate filaments.
Microfilaments are consist many linked monomers of a protein known as actin, that combines in a double helix with a diameter of about 7 nano-meter and functions as serving tracks for myosin (motor protein).
Microtubules are arranged in a form of hollow straw like structure made up of consist of tubulin proteins having diameter of about 25 nano-meter and further consist of two subunits, α-tubulin and β-tubulin.
Intermediate filaments are the cytoskeletal element which are made up of multiple strands of fibrous proteins wounded together having an average diameter of 8 to 10 nano-meter.
I believe that is false, hope this helps
Answer:
The correct answer is option C.
Explanation:
Cilia are tiny hair-like projections or appendages on the surface of the outside of the cells, in respiratory tract cells not move on which cilia are present, however, these projections are helpful in moving debris like microorganisms like bacteria, dust, and toxins out of the lungs.
Cilia can sense bitter toxins or substances in the air and remove or expel it, these present on the epithelial cells in the human airway that taste bitter compounds remove it. Cilia moving more rapid in turn of toxin response. The exposure time has no effective role in expelling the toxin by cilia.
Thus, the correct answer is option C.
