The asthenosphere occupies a majority of the mantle.

TRUE

False  

Explanation:

The asthenosphere constitutes to about 180 km of the total mantle which is almost 2900 km. As compared to asthenosphere the total area covered is very less.

It cannot be said that it covers a large area of mantle. The asthenosphere is the highly viscous but mechanically weak and ductile region which lies in the upper part of the mantle.

It lies just below the lithosphere in between 80 to 200 km below the surface.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
