Answer:
(B) semiconservative.
Explanation:
According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.

Answer:
Henri Becquerel and the Curies worked with uranium, radium, and polonium, all of which give off radiation.
Explanation:
Henri Becquerel and Marie Skłodowska-Curie discovered the process of radioactivity. They were awarded Nobel prize for their work. Radioactivity is the process in which an unstable element emits energy in the form of radiation. This process also produce a lot of heat. Radiations are very harmful for human health however they have wide applications in modern technology.
