The big one is their jaw suspension. its alot to look at but just Google like hyostylic jaw suspension. basicly the jaw is suspended from the cranium by a hyomandibular arch. the "Bones" that make it up are homologous with less primitive fishes as well as our,human, inner ear.
There are several homologous features found on sharks. A few are their fins, their jaw suspension, their skeletal system, and several other things.
Homologous pairs of chromosomes are not normally found in a zygote.
In the diploid cell nucleus there are homologous chromosomes. During meiosis homologous chromosomes pair each other and bring about crossing over to inter change genetic material. This is how new combination of genes are created in the male and female gametes.
Homologous structures are the same body parts found in different species that look different and do different things that are also made of the same thing ex. the human forearm and the wing of a bird are composed of the same bones however have a completely different appearance and function.

It is found on the non homologous part of the X chromosome.
Chromosome pairs that contain matching information are called "homologous".
A homologous structure is a structure found in two very different animals that has a similar form in both animals. For example, the bones of a human hand are homologous to the bones in a bat's wing or a whale's flipper. Structures that appear very similar suggest that two animal may be related, as in humans, bats, and whales, which are all mammals.
Sharks biomes are ocean biomes. A biome is the habitat that something would be found in. In this case talking about sharks, the biome is the ocean since that is the habitat that sharks are found in.
The rumen is a main one, though that is not found outside of the cow, rather inside. The bulkiness, position of the ears and shape of the head are special structures that identify a cow as a cow. See the related question below.
Homologous Chromosomes
at the same place on homologous chromosomes source: Alleles of a gene reside at the same locus on homologous chromosomes.
