Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.
Answer: '' any of the answers are correct'' . In cells, genes are segments of DNA that code for proteins; not sugars or complex carbohydrates, or lipids, but proteins. The code in the sequence of nucleotides in a gene specifies the sequence of nucleotides in messenger RNA which in turn specifies the sequence of amino acids in a protein. The sequence is variable because of mutations which can change the sequence of amino acids in the protein coded for by that gene. Therefore, in evolution, a change in a single code for a single amino acid may have an effect on individual survival. Proteins carry out many functions in a cell such as any of the answers are correct. ♡ hope this helps ♡.
