False, Xylem transports water.
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
American prairie, bison and badgers don't live in any of the other options naturally.
Answer:
The correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
Explanation:
The way one could engineer bacterial cells to produce a human protein is by allowing bacteria to taking up the recombinant DNA. This recombinant DNA are inserted in the form of the vectors.
Recombinant DNA technology or RDT allows individual fragments of DNA from any donor human genome to be inserted into vector DNA molecules with the help of the specific restriction enzyme for both vector DNA and donor DNA.
Thus, the correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
