A researcher inserted the human gene for the protein hemoglobin into a plasmid. The plasmid was taken up by a bacterial cell through the process of transformation. The bacterial cell utilized the gene to produce a protein. However, the protein did not have the same amino acid sequence as hemoglobin has in a human cell. In fact, the protein in the bacterial cell was much longer than in the human cell. How can you explain this?

one would be wind another would be water density

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
