A cytoskeleton is:. a. a structure that aids in the process of cell division.
b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.

e

Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.

1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.

2. The cytoskeleton provides support and shape to cell.

3. It help in transporting substances through cell.

4. It help in phagocytosis.

5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.

6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.

the answer is a) a shiprock was formed by igneous process
