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.

Molodets [167]
Correct Answer:
Option B. The creation is a solution

Since, the powered substance is fully dissolved in the water the resulting mixture will be a solution. As we are dissolving the powered substance in water, water will be our solvent and the powdered substance will be the solute. A suspension is the type of mixture in which solute particles are not completely dissolved in the solvent. Therefore, the correct answer to this question is the creation is a solution.
