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:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.
