Which of the following is NOT a function of microfilaments?
Select one:
- Cellular movement
- Structure
- Hydrolysis
- Cilia movement
- Contraction
Answer :- c) hydrolysis
Reason:- Hydrolysis is not a function of microfilament, as its functions include-Cellular movement, Structure, Cilia movement & Contraction. Other functions are change in cell shape, endocytosis and exocytosis.
Which of the following is NOT a function of microfilaments? Select one: - Cellular movement -...
of the three types of fibers; microfilaments (or and intermediate filaments are fibers with diameters in a Microtubules are the filaments) are the middle range. Microtubules are hollow rods about 25 nm in diameter and 200 nm to 25 um in length. Microtubule fibers are constructed of the globular protein A tubulin dimer consists of two slightly different polypeptides: a-tubulin and B-tubulin. Microtubules shape and support the cell and serve as tracks to guide motor proteins carrving organelles to their...

Please thoroughly explain why each of the answers in correct or incorrect. Which of the following statements about the cytoskeleton is incorrect? A. The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a few simple types of proteins into large aggregates. B. Microfilaments are structurally rigid and resist compression, while microtubules resist tension (stretching). C. Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other...

Which of the following statements regarding cellular division is TRUE? A) the movement of chromosomes along microtubules is an emergencies reaction B) Astral microtubules are capable of anchoring the mitotic spindle by overlapping with microtubules from opposite poles c) during anaphase, deploymerization of the microtubules is intimated at the + end d) Kinetochore microtubules are attached directly to the centromere by the time the cell reaches prometaphase e) there is more than one true statement above
8. In which one of the following cellular processes is DNA involved? (Select all that apply.) DNA replication transcription translation transcription and translation 10. Dogs have lots of fur that they need to keep warm during winter months. However, this makes them prone to overheating during summer months. Luckily, dogs are commonly observed "panting," which is a method used by dogs to exchange hot air for cool air thereby decreasing their temperature. What qualification life would BEST explain this? reproduction...
