Answer:
The correct option is A. Coal use in steam engines led to easier access to goods.
Explanation:
Coal is used in steam engines as a fuel. Coal is one of the cheapest source of energy and hence it has been serving mankind with various benefits since a long period of time.
The coal-based steam engines played a very important role in the developments made during the Industrial Revolution. Many industries started using coal as a power material and made progress.
The steam engines made it possible to transfer goods from one place to another very easily. As coal was a cheap source, hence trading of goods by steam engines was not very costly.
The enzyme known as DNA polymerase is responsible for creating DNA from nucleotide monomers. The enzyme's functions are indicated by its name, DNA polymerase. The term "DNA" refers to the fact that it generates DNA utilising nucleotides. "Polymer" signifies that the enzyme is converting monomeric nucleotides into a polymer molecule. Lastly, "ase" refers to an enzyme.
<h3>What role does DNA polymerase play ?</h3>
The primary role of DNA polymerases is to preserve the genome and guarantee that the genetic code is reliably transmitted from one generation to the next.
- The essential enzyme for replication in eukaryotes is DNA polymerase. Additional DNA polymerases are used for primer removal, repair, and proofreading.

Answer:
Parathyroid hormone increases the level of calcium while calcitonin hormone decreases the level of calcium in the blood.
Explanation:
Parathyroid hormone is a type of harmone which is responsible for balancing calcium in our body. When the calcium level lowers in our body, parathyroid hormone is secreted and calcium is absorbed from the bones and fullfilled the requirement of the body. If the tumor secreted calcitonin hormone instead of parathyroid hormone, the calcium level in the blood is lowered because it acts to the opposite of parathyroid hormone.
