The legislation authorized Medicine Chest be carried on every American Flag vessel of more than 150 tons back in the 1700's, so long as it had a crew of ten or more. A loose network of marine hospitals, primarily in port cities, was established by Congress to care for disabled and sick American merchant seamen around 1798. Federal entities, namely, the Marine Hospital Service, the Public Health and Marine Hospital Service, and lastly the Public Health Service continued to give healthcare to merchant seamen until 1981.

Answer:
c. If the double helix were unwound, each nucleotide along the two parent strands would form a hydrogen bond with its complementary nucleotide.
Explanation:
According to the Watson-Crick model, two DNA strands are held together by complementary base pairing wherein each nucleotide of one DNA strand forms hydrogen bonds with its complementary nucleotide present in the other strand. During DNA replication, two DNA strands are separated by the action of helicases enzymes.
The separated DNA strands serve as a template for DNA replication. Here, each nucleotide of the template DNA strand binds to its complementary nucleotide by hydrogen bonds. For example, adenine of the template strand forms two hydrogen bonds with thymine while guanine forms three hydrogen bonds with cytosine.
