The photic zone is the zone where light can be received, it's usually from 0 to 200 m deep, but this depth can be modified by the turbidity of the water. The aphotic zone is the zone where no light is received, it goes from 200 to the bottom of the sea.

A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.

2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA

D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals

C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
