Answer:
comparative anatomy:
compares the genomes of different organisms
compares the limbs of different organisms
molecular biology:
compares fossilized structures to living organisms
compares cells of organisms
EXPLANATION:
Comparative anatomy is the study of similarities and differences in the anatomy of different species.
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

which interact with actin when calcium is present.
The crayfish have its nerve cord on the ventral side rather than on the dorsal side. The ventral side is under the Crayfishes' exoskeleton, as opposed to the dorsal side where the exoskeleton is . If it is attacked it will be from the dorsal side and the nerve cord would be snapped easier. The function of the nerve cord is that if it gets attacked by a predator they will go for the top and it will still be able to move.
