The statements that illustrate the regional specialization of human nervous system are-
a. Sensory information may be processed in the occipital lobe or the temporal lobe.
c. Reading a printed word out loud and then thinking of a related word involves the visual cortex, Broca’s area, and the frontal and temporal lobes.

Cilia and flagella bend because of a motor protein called dynein.
Explanation;
-Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts.
-Cilia and flagella are formed from specialized groupings of microtubules called basal bodies. If the protrusions are short and numerous they are termed cilia. If they are longer and less numerous they are termed flagella.
