The cells of diplomonads and parabasalids have modified mitochondria.
Diplomondas are small zooflagellates that inhabit the digestive systems of various animals, including termites, rats, and humans. Diplomonads do not posses true mitochondria, and thus they cannot perform respiration and instead must obtain their energy from fermentative processes. Parabasalids on the other hand also lack true mitochondria and instead contain small hydrogenosomes which apparently developed from reduced mitochondria.
The answer is C.
Hershey and Chase did an experiment to determine whether it was the protein or the DNA that was the transformation principle in viruses by infecting bacteria cells with a virus.
They tagged the protein shell and the DNA and introduced them into a culture of bacteria cells. They concluded that it was DNA that entered the bacteria cells and not the protein.
Again the answer is C.
