In evolutionary theory, homologous traits are those with a similar structure and function derived from a common ancestor. Analog
ous traits represent adaptations to a similar environment, but from distantly related organisms. Consider the structure and function of the flagella found on eukaryotic and prokaryotic cells. Are the flagella an example of a homologous or analogous trait? Defend your answer.
Prokaryotic flagella are analogous to eukaryotic flagella-like structures
Explanation:
Beyond that they have the same function, flagella from prokaryotes have very little in common with flagella from eukaryotic organisms. Eukaryotic flagella are composed of microtubules. On the other hand, bacterial flagella are composed of polymers of flagellin, which is another unrelated protein. Homologous structures indicate the existence of a common origin (common ancestry), and it is not the case.
<span>It is important because if the shape of the enzyme changes it may not function or it may function differently and if they don't hold them they will fall out of plant & plant will die.</span>
Anaphase 1!! Metaphase is when the chromosomes move near the equator (middle) think about it was “M” for metaphase and “M” for middle! This happens in both metaphases!
For the answer to the question above, I believe the answer is <span>A. vaccine helps the body develop memory cells that make immunity last, whereas injection of antibodies only produces a temporary immunity.
I hope my answer helped you. Have a nice day! </span>
