Answer:
Fossils of mollusks would be found in lower strata than that of arthropods
Explanation:
Fossils are found in different layers of sedimentary rocks. The fossils of organisms that evolved earlier are found in the lower strata while those evolved later are preserved as fossils in the upper strata. If mollusks evolved before arthropods, fossils of arthropods would be present in upper layers while those of mollusks would be found in deeper layers.

Kinesin -1 is the major anterograde motor which helps in the transportation along micro tubules. This is important for the proper transport of the mitochondria, Golgi derived vesicles, endoplasmic reticulum tubulin, mRNA and intermediate filament sub units.
It moves along the micro tubules and for this task it gets energy from the adenosine triphosphate.
The heavy chain of KInesin 1 is made of globular head via short flexible neck and has a light chain as well which ends in the carboxy terminal.
