The answer is <span>C.silent.
Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.

Answer:
Calcitonin
Explanation:
Calcitonin hormone is released by the para follicular cells of the thyroid gland. This hormone works against the parathyroid hormone.
Calcitonin hormone regulates the level of calcium by decreasing the blood calcium level. This hormone inhibits the osteoclast activity of the cells and decreases the absorption of calcium in pregnant women and child. Hence, calacitonin decreases plasma calcium levels in pregnant women and children.
Thus, the correct answer is option (B).
Answer:
The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.
Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.
Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.
The protein thus formed corresponds to a particular trait ( like eye color, hair color).

Answer: signals fair weather and an approaching cold front
A student notices cirrus clouds characterized by long, thin, wispy strands of clouds in the sky. It generally appears white or light grey in color and signals fair weather and an approaching rain or cold front.
<span>A sample that is large and randomly selected<span> is most likely to yield generalizable results. A large and randomly selected sample shows the real diversity of the population with little relevance of bias within the findings and produces generalizable results. Also, the results from the sample gives accurate representation of the larger population and are easy to use.</span></span>
