The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.
According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.
The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.
In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.

Answer:
Sensitization.
Explanation:
Hypersensitive reaction may be defined as the exaggerated or hyper response of the immune system. Hypersensitive reactions can occur due to auto immunity and allergies.
Type I hypersensitive reaction is mainly mediated by IgE antibodies. The sensitization towards particular stimuli like pollen grains may exaggerate the Type I hypersensitive reaction.
Thus, the correct answer is option (1).
