An antigen triggers a response from the immune system and an antibody is produced. All antibodies are immunoglobulins, therefore, the correct answer is immunoglobulin. More specifically, an immunoglobulin is a protein produced by plasma cells to fight and neutralize pathogens. To do so, the immunoglobulin has a specific region which is complementary to a specific region of the antigen. Immunoglobulin's mechanism of action is to bind to the pathogen and either block its action or trigger a response of other cells of the immune system.
Answer:
The way to find a codon is by arranging the sequence of nitrogenous bases of the mRNA in groups of three, the triplets. Once the codon is found, the anticodon corresponds to a complementary triplet to that codon.
Explanation:
Codon corresponds to a triplet of mRNA nitrogen bases encoding an amino acid. Anticodon is responsible for carrying amino acids to the ribosome, according to the information of the mRNA, and the sequence of its triple must be complementary to that of the codon mRNA.
If, for example, a codon of the mRNA is AUG, its anticodon of the tRNA must be UAC, that is, complementary. Then, for the indicated exercises:

Answer:
B. A bias could skew the information and make it
inaccurate.
Explanation:
After looking at the diagram of organism, the sequence that will best represent the food chain within this particular food web is sedges-ants-frogs-kookaburras. So the correct answer choice will be number 2.
