C seems like the answer because at the end of South America, there's nothing blocking the two oceans there from connecting. All of the oceans are connected together. They're just different because of where they are and the conditions of that area of earth.
I dont' think water flows under the continents either so D doesn't sound right at all. A is just beyond logical because there's no way that has anything to do with how the oceans are connected to each other. B MAY be the answer but I'm leaning more towards C.
Answer:
The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.

gained by a process of experimentation and investigation --> TRUE
proven to be true by scientists around the world.---> FALSE, BECAUSE EXPERIMENTATION AND THEORIES LEAD TO TEMPORAL TRUES, WHICH MAY BE PROVEN TO BE FALSE, BUT WHAT IS BELIEVED TO BE TRUE TODAY MAY NOT BE TRUE TOMORROW
never changed once it is proven and supported by experimentation.---> FALSE AS EXPLAINED ABOVE

Answer:
The correct answer is - cell must make a copy of every chromosome.
Explanation:
Mitosis is the cell cycle where cells form two identical daughter cells. It is essential to the daughter cells have a copy of every chromosome, and therefore, It copying the chromosomes during mitosis and separating the chromosome copies to provide a new cell with a complete set of chromosomes.
In the Interphase phase, the DNA breaks up evenly so that each new daughter cell has the same amount of DNA that helps in providing a complete set of chromosomes.
