Answer:
The correct answer is B make cells produce a functional CFTR protein.
Explanation:
Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.
If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.
I think B is the correct answer. Answer choices C & D are about dolphins, but they do not have anything related to negative effects surrounding human and dolphin interaction. A, on the other hand, may seem like a good choice, but then again, the answer is too vague.
When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.
Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
