What is meant by suggesting that Earth's oceans are connected?
Katen [24]
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.

Viruses can be used to insert genetic material into cells during gene therapy

Explanation:

Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.
