Answer:
The correct answer is "the induced fit model".
Explanation:
The first model that looked to explain the enzyme and substrate interaction was the "lock and key" model. Although this model helped scientists to understand the specificity nature of the interaction enzyme-substrate, it does not reflect reality since enzyme was portrayed as a lock with a structure that doesn't change during the catalysis. Then half century later "The induced-fit theory" was proposed which fits much better the newer version of the enzyme action model. In this theory the enzyme is partially flexible and its structure changes as a result of its interaction with the substrate.
After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

The writer could assert Taxonomy.
Which is responsible for many scientific classifications and
influences in various field of life sciences or biology. Evidences that Taxonomy uses to group or
categorizes species range from

<span><span>
2.
</span>Comparative anatomy</span>

3.

We also suggest that taxonomy has played various roles
mainly in many aspects in Zoology, Botany, Anatomy and Physiology –aspects that
include animal and human structures and functions. As the biotic community is
so diverse it is classified to Biodiversity and the existence of properly
assorting by set standard.
