Answer:
Option-B
Explanation:
The theory of endosymbiosis provided the evidence which suggested that the eukaryotic organelles like mitochondria and chloroplast evolved from the smaller prokaryotes which were once independent organisms.
These prokaryotes, when engulfed by larger cells, formed symbiotic relationship among themselves and later evolved into the organelle.
In the given question, since the zoochlorellae contains paramecium bursaria within its cytoplasm which could form the symbiotic relationship. This could act as an evidence of the endosymbiotic theory.
Thus, Option-B is the correct answer.
I'm thinking possibly d but I'm only a teen and I'm not sure

Answer:
The correct option is D
Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, <u>it is </u><u>not true</u><u> that it involves just the x allele and thus affects males more often than females</u>.
