C) His work proving that unseen bacteria can cause disease.
Answer:
Due to the presence of three hydrogen bonds.
Explanation:
DNA or deoxyriboucleic acid is made up of polymers of nucleotide. The single nucleotide consists of a nitrogenous base, a pentose deoxyribose sugar and a phosphate group.
The nitrogenous bases are adenine, guanine, thymine and cytosine. Adenine is bonded with thymine with two hydrogen bonds whereas cytosine is bonded with guanine with three hydrogen bonds. Three hydrogen bonds are difficult to break as compared with two hydrogen bonds. Hence, DNA with more GC content is difficult to denature.
Answer:
causes them to be different types. When sediment is compacted and cemented together, it forms sedimentary rock. When magma cools, it hardens to form igneous rock. ... They model the formation of sedimentary rocks using hard candy, and view a video showing igneous rock formation as magma cools.
