A cephalopod is a predatory-like mollusk of the large molluscan class of Cephalopodan animals. This includes cuttlefish, octopus, squid, and/or nautilus. They are animals that live in the ocean. Additionally they eat foods like fish and jellyfish on regular and customary occasions. They sometimes possess cannibalism by eating their own species, which is absolutely crazy. Anyways, I hope that this has helped you today.. :)
Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.
Karyotype helps to study the presence and location of genes on chromosome. This also helps to find the mutations such as duplication or deletions.
