Answer:
They are thick, strong and made up of thousands of tubulin which are spiral in shape.
Explanation:
In eukaryotic cells, they have microtubules which are fibres serving as tracks for cell to cell transport and regulate the shape of a cell.
Microtubules are different from other cytoskeletal filaments because they possesses a cylindrical shape with the tube having a larger diameter of 20-25 nm as compared to microfilament that have a diameter of 3-6 nm.
Microtubules are made of subunits of proteins called tubulin named alpha and beta that is not present in other cytoskeletal filaments.
(D)an atom can join with other kinds of atoms.
Basically he explained what a molecule is.
Answer: 100%
Explanation:
if the mutation presents autosomal dominant inheritance, each affected individual will show 100% alteration in the protein, thus , being dominant, it is considered that the disease pattern will predominate even if it has genes that do not express it since these will be recessive and canceled by the dominant ones.
