There are THREE (3) phyla or categories of fish.
These phyla are:
1) Agnatha - jawless fish ; around 50 species in the world
2) <span>Chrondrichthyes - cartilaginous fish ; around 600 species in the world
3) </span><span>Osteichthyes - bony fish (divided into ray finned group and lobe finned group) ; around 30,000 species in the world.

Answer: They possess different functional groups.
Explanation:
Organic compounds are molecules composed of many carbon atoms bound together and in turn bound to hydrogen atoms. These molecules form the lipids, proteins, carbohydrates and nucleic acids that constitute all living beings. The reason why there is so much variety of organic molecules is because each one can have one or several <u>functional groups in different positions, which gives them unique properties.</u>
So a functional group is a group of atoms linked in a certain way, which present a specific physical-chemical structure and properties that characterise the organic compounds that contain them.
Examples are:
- Lipids: A carboxylic acid
- Proteins: A carboxyl group and an amino group
- Carbohydrates: An aldehyde or ketone group
- Nucleic acids, Nucleotides: A phosphate group
A star's color often times determines the temperature of it. In this case, red would be the coolest color (and would be cooler than orange).
Offspring different from parents would belong in sexual reproduction. Sexual reproduction makes the offspring different from the parent(s), while asexual reproduction makes somewhat of a clone of the parent.
When a scientist say's organisms have the same universal genetic code it mainly means that the
"organisms use the same four nucleotide bases." Now <span>organic molecules that serve as the monomer units for forming the nucleic acid polymers.
Hope this helps!
