Answer:
The mouse CFTR gene and human CFTR gene encode proteins that can serve a similar function.
Explanation:
CFTR (Cystic fibrosis transmembrane conductance regulator) is the important membrane protein that plays an important role in the transfer of the chloride channels in the body.
The mutation in CFTR is responsible for cystic fibrosis. As the information given in the question, it might be possible that the gene CFTR plays the quite similar role in both human and mice. These gene might not necessary to have same DNA sequence but perform the similar function.
Thus, the correct answer is option (C).
Answer:
I think the answer you are looking for is energy.
Explanation:
Energy flows through an ecosystem from the plants to the primary, secondary and tertiary consumers. The energy also decreases as it is passed on.
