Proteins serve as antibodies.
Answer:
The given blank can be filed with stasis.
Explanation:
There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.
Microtubules are macromolecules that build both, cilia and flagella.
<span>Microtubules are cytoskeletal fibres that are formed by polymerization of α,β-tubulin and they are important components of cilia, flagella and some other cellular structures. Cilia and flagella are very similar in their organization, both have a central bundle of microtubules-axoneme. Axoneme is compound of nine outer doublet microtubules which surround a central pair of singlet microtubules. Even thought cilia and flagella are structurally similar, they are differentiated based on their function and/or length. Flagella are longer and the primary role of the flagella is locomotion. On the other hand, shorten cilia often has the function in sensing the extracellular environment.</span>
