The right option is; D. Samples of ocean water tested off the coast of South America contained the same salt content as oceans near Africa.

Continental drift is the theory that all of the earth's continents were once together and formed a large single landmass known as Pangaea but over geologic time, the continents have moved relative to one another, and across the ocean bed. "Samples of ocean water tested off the coast of South America contained the same salt content as oceans near Africa" is not a geological clue used to support the theory of continental drift because the theory only explains why the same species of organisms (plants and animals), rock components and fossil remains are found on different parts of the earth surface that are separated by large distances of sea.

krek1111 [17]

Answer;

petit arm

Explanation;

All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.

The symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.
