Answer:
A. maintenance of axons is not a cellular activity associated with microtubules.
Explanation:
Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
They both have genetic information and they both contain ribosomes ,,both have plasma mebrane ,both have cytoplasm and both not visible by the naked eye
ATP stands for adenosine triphosphate which is the energy currency of the cell while ADP stands for adenosine diphosphate. The difference primarily between the two is the number of phosphate groups in the molecule. ATP has three phosphate groups while ADP has only two phosphate groups
I believe the answer is b.
