Answer:
1.
Explanation:
That is not true! Fossils are found in from germany to australia (all around the world)!
The paramecium would not be able to get rid of excess water so the cell would burst.
FUNCTION OF THE CONTRACTILE VACUOLE:
- The contractile vacuole is an organelle present in protist organisms like paramecium, amoeba etc.
- The contractile vacuole functions to regulate water balance in the cells of organisms that they are found. Contractile vacuole performs this function by storing excess water and expelling the out of the cell.
- Hence, if a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, the paramecium would not be able to get rid of excess water so the cell would burst.

Answer:
The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).
Explanation:
The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.
Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.
